I haven't seen any success stories on these forums, however it IS possible to do.
The sequence of steps goes something like this:
1) Turn off wifi network managers (NetworkManager et al)
2) Remove your wifi module, modprobe it (it doesn't work for me otherwise, YMMV)
3) iwconfig <DEVICE> mode ad-hoc essid "G1 "
4) ifconfig <DEVICE> up
5) iwconfig <DEVICE> mode ad-hoc essid "G1 "
6) dhclient <DEVICE>
Where <DEVICE> is of course your wireless device, whether it's wlan0, eth0, eth1, etc.
I realise these commands look odd, but it's the only way I've been able to *reproducibly* connect. It may be my horrible broadcom wireless chipset drivers, but I couldn't say for certain.
If dhclient fails to get an address, it didn't work.
I'd be interested in other peoples' success; perhaps there is an easier way.
Here's an example start|stop script:
Code:
#!/bin/bash
case "$1" in
start)
/etc/rc.d/autowifi stop 2>/dev/null
rmmod wl 2>/dev/null
modprobe wl
iwconfig eth0 mode ad-hoc essid "G1 "
sleep 3
ifconfig eth0 up
sleep 3
iwconfig eth0 mode ad-hoc essid "G1 " 2>/dev/null
sleep 3
dhclient eth0
;;
stop)
kill `pidof dhclient` 2>/dev/null
ifconfig eth0 down
ifconfig eth0 up
/etc/rc.d/autowifi start || exit 1
;;
*)
echo "USAGE: wifitether start|stop"
;;
esac
exit 0
Note for script usage: I use autowifi to manage wifi networks normally. If you want to use this script, please replace /etc/rc.d/autowifi with your network manager of choice, wl with your wireless module, and eth0 with the wireless device.
Trying to do this but not having much luck :/ Using PuppyLinux On both computers.
On the laptop, I think it's a driver issues. I can't get past the first iwconfig line, with or without the wlan0 module loaded.
On the pc without the module i get the same as the laptop. With the module still loaded, I get to 'dhclient wlan0' then error... Bash (or sh): dhclient: command not found
*do I need to use the script part too? or is that just for future automatic setting up..Do i need to go back through the network setup and input the ip,mask,dhcp etc?
I see dhclient in /sbin but idk. I'm new to *nix and trying to use the tetherwifi.apk with my G1/PuppyLinux project. Unfortunately I can't get past the wlan(wireless 3g internet) & boot from USB G1(sd memory) parts:/
If you have anyideas that'd be great! I'll post back here if I get everything working..
theres a great app in the dream app forum that lets you do wifi tethering, ive got it workng on both linux and windows7.
are you referring to TetherWiFi ?
If so, I have that one working cool in windows (one of my favorite apps!). I just have no exp with linux About the farthest I get is the browser hanging longer than usual before timing out. I've removed/installed the wlan drivers. set the ip,mask etc to match what shows up in xp. Just can't get a connection :/
Silly question, but are you sudo/root when you try to dhclient? If yes, try /sbin/dhclient wlan0
The script is just an example for future automation, yes.
If you can't get past the first iwconfig line (which puts the NIC into ad-hoc mode), the card or the driver may not support ad-hoc currently.
Something is wrong here. You put the PC in Ad-Hoc mode and then run dhclient on it? Why?
Also does your phone really see the Ad-Hoc network? I have tried with linux, windows 7 and windows XP and the phone sees neither of them. And many other people have reported the same. The phone doesn't list Ad-Hoc networks. It is possible, though to put the phone in ad-hoc mode and connect to it from a PC.

1) The tether application sets up a dhcp server
2) It's easier than setting the ip/gateway/broadcast yourself
Hmm with ubuntu 8.1 the ad hoc tethering just works. Nothing special to do other than know the ssid is g1.
Is this method for connect PC using G1 internet or connect G1 to PC internet?
>>> <<<< >>>> <<< >>> <<<>>>>
yes if you use the network manager from ubuntu builds, it will automatically configure the ad hoc, works out of the box
Any way to connect the G1 to the PC Internet connection with ad hoc connection? without the use of the Access Point or router, just with a wifi card on pc (ad hoc connection).
Any Idea?
Before i start i want to let people know YES I DO HAVE A WIRELESS ROUTER!! So please do not respond telling me to just go buy a router.
REQUEST - Reverse wired tethering. I.E. Sharing PC's iNet connection with your phone via USB.
REASON - My university's wireless is locked down and does not allow mobile phones, pda's to connect up to our wireless without submitting MAC for approval. Looking to sync certain apps without using my data connection.
I dont know if anyone has played around with trying to get this working or not. I know its a small market of people who may be interested in this, but for certain places (CANADA) where data charges are WAY to expensive this could be handy for students at UNI where wireless is not an option.
get a second wifi adapter on your laptop, and share your uni wireless network connection with the second wifi adapter. Use a hidden SSID, then no one will know what is going on
This was asked a couple of times before here and I remember people saying you couldn't reverse the tethering.You could try though.

Thats a good idea xD
Hey guys,
I have been trying to find a way to do this for a long time.
The best solution i have found (actually the only solution) is Connectify. The only downside is you must have Win7.
What it does is turns your wifi adapter into a HotSpot, even if you are using wifi to get the net in the first place. Its a great tool and should be what your after.

thank you so much for this
Your best solution is the WiFi adapter. You could most likely get away with a SOCKS proxy over USB, possibly using adb, but it would be complicated, unstable, and messy.
I still don't know you just don't use your wireless router. I assume they have wired. Clone your PC's mac address and hook it up. Universities are retarded with that crap. They have the worst networks and security.
If no wired, then what podunk place is it? haha
Even if they had only wireless , you could set up a wlan client and repeat it. DDWRT, etc, ftw.
Just get backtrack for your laptop and spoof your mac to all 0 then grab connect to the network at your school the spoofed mac will allow you to browse so long as no other encyption is on the network such as WEP or WPA.
then you can try to flood all the ports on the network so no one else can connect then spoof your phones mac by conneecting to your laptop through wireless as an adhoc connection and while staying connected through adhoc load a second server through the same wireless network card and you can connect to the achools network again. and walla...

so simple, i dunno why i didnt think of that. thanks! lol
Well its quit simple once you learn your way around linux...
If you have any experience with *nix, you may want to look at Cyanogen's original usb tether shell script:
http://github.com/cyanogen/android_vendor_cyanogen/blob/master/bin/usb-tether
Basically you could use the internet connection sharing function that comes with all popular OSes and access your uni's network on your phone. You must have Cyanogen mod or another mod using his kernel. Not yet working on OSX for some reason. Tested under Windows 7.
First you'll need to figure out what IP address range your computer's DHCP server is using. This is normally fixed for each OS. For Windows 7, it's always 192.168.137.0/24.
For OSX or Linux, you can setup connection sharing (for some other connection because we don't have the USB interface yet) and ifconfig.
Second is to enable the USB connection on the phone's side. Type the following command in any console program, like Connectbot. (You must use a console program as opposed to adb because you will lose USB debugging once the USB network interface is enabled.)
Code:
su
cd /sys/devices/virtual/net/usb0
ifconfig usb0 192.168.137.200 mask 255.255.255.0
echo 1 > enable
The first line makes you the superuser. (Skip if the command prompt is #)
The second line land you in usb0's directory under sys. We'll need to type the disable command later, so it's easier if we're here.
The third line brings up the virtual usb network interface and sets its IP address.
The IP address should be in the same network (i.e. IP address range) you obtained in step 1. Say if the original is 192.168.137.1 in a /24, you can use 192.168.137.2 through 192.168.137.254
This actually enables the usb interface.
You will now see a new network adapter is recognized by your computer. Set up connection sharing to share your internet TO that adapter.
Make sure you have connection by pinging your computer from your phone.
For example:
ping 192.168.137.1
Now you'll have to change the routes so traffic go through the USB cable instead of the mobile network.(# is the command prompt, do not enter)
# busybox route
check the line starting with "default". Write down the ip address after it; call it IP1.
# getprop net.dns1
Call the IP returned IP2.
Code:
busybox route del default gw IP1
busybox route add -host IP2 rmnet0
busybox route add default gw 192.168.137.1
The first line deletes the old default route via the mobile network.
The second line adds an "exception" for your carrier's DNS server.
The third line adds the new route via USB. You should replace the address at the end with the IP address from the first step.
Your network should be working now. Test by visiting some website that is only available on campus or by traceroute.
You must make sure the mobile network is always connected though. This is because domain names are still resolved by your mobile carrier. If you ever lose your mobile connection, the routing table will be changed as well.
To disconnect:
Make sure you're still in /sys/devices/virtual/net/usb0.(Use pwd if unsure.)
Code:
netcfg usb0 down
echo 0 > enable
The usb interface will disappear on your computer.
Now switch the phone to airplane mode and back to re-enable mobile network.
The disconnect step should always restore your phone's state.

It's really sad that Android can't reverse tether. If you want to use your laptop's AdHoc connection you have to do serious hacking to the tiwlan.ini and the wpa_supplicant.conf. There is no way to connect via bluetooth ar USB.
I'm seriously considering WP7 now for my next OS of choice... A nd for everyone saying "go buy a router" - go buy a router and stick it up your .... nose.
Hi,
I have the same problem. No WiFi in my work and no WiFi in my current home (a Resident Hall). There's no possibility to buy a WiFi router, of course. I tried to hack the system to connect ad-hoc networks but it didn't work.
I have found some interesting resources:

I have a HTC Magic with the ADP-DRC83 hacked ROM with Usb tethering integrated. But usb0 interface in the mobile is configured to provide Internet connection (as gateway) to the PC, not the reverse functionality: connecting the mobile to Internet through the PC. So, all I need is to change the gateway in Android and then configure a NAT-DNS in my linux PC (easy with iptables and dnsmasq). But, I don't know how automatize the process exactly.

Silly ragin' cajun.
Ok, now it works. Here it's my procedure for a HTC Magic (Sapphire) without any APN previously configured from Telecom provider and ROM CSDIv4.
In the mobile by using Better Terminal:
Code:
su
cd /sys/devices/virtual/net/usb0
echo 1 > enable
ifconfig usb0 192.168.2.2 mask 255.255.255.0
busybox route add default gw 192.168.2.1
setprop net.dns1 8.8.8.8
In the linux computer:
Code:
sudo sysctl -w net.ipv4.ip_forward=1
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo iptables -A FORWARD -i usb0 -j ACCEPT
sudo ifconfig usb0 192.168.2.1 netmask 255.255.255.0
Android Market downloads and location service don't work but I think is possible if you switch on the WiFi.
Update: Syncronization, Android Market downloads and location service don't work even the WiFi antenna is switched on. I have added the iptables commands also.
Well gosh, reverse wireless tethering is so much simpler
There are another similar thread: http://forum.xda-developers.com/showthread.php?t=522498
How can I join an Android device to a Bluetooth PAN (Personal Area Network) as a client? In some areas, the only internet connection available would be to tether it through another cell phone via bluetooth PAN (other phone has no wifi).
Solutions that require rooting or config file editing are OK.
I've searched alot, but all results are about going the other way - tethering other devices through the Android.

It's Linux, man, all you need is setting network config I was using reverse tethering for some time, this is my script (run on PC):
Code:
sudo pand --listen --role NAP
adb shell pand --connect XX:XX:XX:XX:XX:XX
sudo ifconfig bnep0 192.168.101.1
adb shell ifconfig bnep0 down 192.168.101.2 up
adb shell route add default gw 192.168.101.1 dev bnep0
adb shell setprop net.dns1 192.168.101.1
Of course you should omit 1st and 3rd lines.
Are you sure second phone supports PAN connections, not DUN? PAN is quite complicated for phone, because it requires full NAT.
And you will have problems with Android Market and some other apps. Internet is configured at linux level, Android OS don't know about it, so if application asks: "Do we have internet connection?", Android replies: "No". Android Market will wait for connection even if there is one.

But most of the apps don't check internet status and just use it - they will work. AFAIR I couldn't use Market, GTalk and syncing feature, but Browser, Gmail and many, many more was working.
If you have any WiFi device then you could connect Android to it. Even if it doesn't share internet connection, Android OS will think, that it does (but will use BT connection configured at linux level ) - then any app should work.
At work I got a laptop with windows XP, There's a wireless network but it's EAP secured and I can't connect to it with the phone (Motorola Milestone - Android 2.1).
Did you manage to make internet work through Bluetooth PAN? I just need to use the borwser, so It's not important if market or other apps don't work.
I have android sdk with adb on my laptop and terminal emulator with busybox on my phone. I'm kind of a newbie in this so some hints would be nice. I think many people like me would be gratefull

And my first post was about what, you think? I don't use it now, but I was reverse-tethering through BT for several months, until I bought some data plan.
Above commands should work for you, but... they will let you connect your phone to PC, but I don't know, how to share internet connection on Windows XP. AFAIR I tried to do it, but failed.
There's a bluetooth network icon. I know it's possible to share the internet connection from my ethernet to the other network cards. So this should work also with the bluetooth network.
I will try the commands and see how it goes.

Unfortunately not ;-) It is a cost of easy-clicking-configuration that Windows has - it's very limited, don't work for BT connections. I guess there is some professional software for internet sharing on Windows, but I don't know one.

I did this with my symbian phone. I managed to share internet to the bluetooth network, but the phone had a bluetooth PAN profile that connected to my laptop.
No! Already I have a bluetooth network set up on my Ubuntu Laptop - pand is running and there is a dhcp server monitoring the interface. What I need is not the below advice, which are commands to run on the PC, but an application / utility / instructions for enabling BLUETOOTH PAN CLIENT on Android. That is what the original question was too! Anybody?

4 of 6 lines of my instructions were for setting Android client: connecting, setting IP, routing and DNS. And yes, they are run on Android, not on PC - I thought you will notice "adb shell" prefixes... You can also use dhcpcd instead of last 3 lines, but if you don't understand, what are you doing, you will have problems anyway.
Maybe anyone with Froyo can confirm that there's still no official option for joining a Bluetooth PAN from Android there?
@Brut.all So I guess there's currently no way to kind of telling Android there's a configured connection on Linux level?
By the way, every Mac allows the creation of a Bluetooth PAN with one click so this would be my usage scenario ;-)
This seems like it should work, and indeed I can use a similar technique from an ubuntu laptop to connect to another device, but my HTC Hero doesn't seem to have hcitool or pand installed on it. I downloaded some prebuilt binaries for them but they don't seem to be able to access the bluetooth device:
# /data/tmp/pand --role PANU --connect 00:17:83:0F:0F:C7 -n
pand[5083]: Bluetooth PAN daemon version 3.36

pand[5083]: Connect to 00:17:83:0F:0F:C7 failed. No route to host(113)
Do all versions of Android come with pand and hcitool? I'm on 1.5 although I'll be reflashing to 2.1 soon.

No, it was added by rom cookers and I don't know how they did this. I think there are missing some kernel modules or something like that.

Thanks, I've got the FroydVillain ROM installed now and can confirm that it comes with pand and hcitool compiled and working.
Reverse tether does seem to work, the method that's worked for me has been to use:
Code:
pand --connect <remote BT device hex address>
ifconfig bnep0 down
dhcpcd bnep0
setprop net.dns1 8.8.8.8
This allows the device to access the internet, and you can ping www . google . com and get a response etc.
However, a lot of android apps (including the built-in google apps for gmail etc) use the ConnectivityService (see source code here) to access the net, and since this method of reverse tethering doesn't change the connectivity state within this service, those apps still believe that there is no internet connection on the device.
I can't see an easy way of "tricking" the ConnectivityService as it appears to have been hard coded to only cater for WIFI and 3G connectivity. So perhaps the only way is to rewrite it.
I've found a few cases of others going through the same issues online, although I think the getMobileDataEnabled return value is a red herring:
(I'm not allowed to post links, so you will need to add http : // www to these
superuser.com/questions/188636/close-connect-android-to-internet-using-usb-tether-through-laptops-newtwork
forceclose.com/questions/2669/connect-android-to-internet-using-usb-tether-through-laptops-newtwork
Looking at the code in ConnectivityService.java it seems that apps must subscribe to this service via getInstance() and then wait for a sendConnectedBroadcast() to occur, triggering them into action (e.g. the gmail app will attempt to sync to the gmail server etc).
Anyone got any ideas for an easier route than rewriting ConnectivityService.java to add an additional connectivity type?
Edit to add:
Found another related discussion at the following site. Seems to suggest modifying the ConnectivityService is the way to go:

Based on the posts I've seen in this thread, I'm guessing I can't use BlueTooth PAN tethering from my rooted Dinc to provide internet access to a Samsung Galaxy Tab???
So has anyone tried to Bluetooth tether a Galaxy tab with a phone?
Thanks for this thread! I just successfully Tethered both internet+gps over bluetooth from my G1 to my AdventVega tablet.
For now I am using GScript lite with the following script commands:
Code:
pand --connect {my phones BT hex address}
ifconfig bnep0 down
dhcpcd bnep0
setprop net.dns1 8.8.8.8
dhcpcd bnep0
(for some reason the first dhcpcd command always says permission denied, but the last one always works)
So...
1) Get in to car with Android phone and Vega Tablet.
2) On phone: Enable GPS/Bluetooth, click GPS2Bluetooth widget button, click WiFi Tether (configure for BT), press to start tethering.
3) On tablet: Enable Bluetooth, click Bluetooth GPS Provider, click Start, click Back or Home, click GScript Lite, click "Connect to BT-PAN" (above script)
4) Run GoogleMaps/Navigation on tablet and enjoy using your tablet as the ultimate GPS navigation system (while streaming Pandora in the background)!
I am very happy. I just wish I could make step 2 & 3 be a single click instead of so many.
NOTE: Must have "Allow mock locations" enabled in Settings->Applications->Development
NOTE2: You must pair your phone and tablet in BT settings (it will never say "connected" though, which is fine)
I tried this, but still no connection between my android phone and the other phone. Is there some other method?
After trying several methods (tiwlan.ini, wpa_supplicant.conf, wpa_supplicant patch) to get my Motorola Milestone to connect to my Laptop's Adhoc wifi network with no success, i finally come up with a solution. Now I am sharing it here hoping it will help those with the same problem.
The idea is to use Barnacle (on Market) to first setup a connection with the laptop, then re-config it to make the sharing work in the reverse direction.
Steps are as followed:
1. Start Barnacle (you may check "Local Mode" in Settings to go ahead without a data connection in phone), then connect your laptop to the wireless network it creates (named milestones or so). After this step, your phone's IP will be something like :192.168.5.1, and your Laptop's IP will be something like: 192.168.5.100
2. Start sharing your data connection from Laptop, in doing that, your Laptop's IP will be forcibly set to 192.168.0.1 (yours may be different, just note that this IP will be used as default gateway we use in the next step)
3. Now the configuration part:
//Start adb shell by entering at Cmd prompt
adb shell
$
su
#
//mannualy set IP for your phone, can be anything in form of 192.168.0.xxx
# ifconfig tiwlan0 192.168.0.2 netmask 255.255.255.0
//manually set the default gateway of the phone to the Laptop's IP at this time
# route add default gw 192.168.0.1 dev tiwlan0
After these steps, the phone can access the internet via the Laptop's connection. We will complete the remaining by manually specifying a DNS for the phone
# setprop net.dns1 #.#.#.# (here you should replace the #.#.#.# to a known IP address of your ISP's DNS, in worst case you may use Google's DNS)
//Now test with ping to see if we receive any response:
# ping -c 4 192.168.0.1 => the Laptop should answer
# ping -c 4 191.168.0.2 => phone are pinging itself, the phone should answer
# ping -c 4 209.85.175.106 => some server in the Internet should answer
# ping -c 4 www dot google dot com => Google should answer
If the tests above are all OK, you are done, enjoy the internet from your phone !
have tried :
+ Mail OK

not working. i follow your guide exactly, but it didn't work. how can you do that? where am i wrong?
Didn't work for me either. After quite a hard experience I've managed to compile a wpa_supplicant with adhoc support for Milestone 2.1-update1 after applying szym's patch, and so far it works fine. The only thing you need to do is substituting the original system/bin/wpa_supplicant for the patched one, and restart wifi. I cant post the link yet because I'm new in the forums, but I'll post it as soon as i can.
I was previously using a stock rooted Nexus 4 (with 4.3) with "OpenVPN Connect" (net.openvpn.openvpn) and android built-in wifi tethering to tunnel tethered clients through the OpenVPN connection. This required some iptables modifications but worked fine.
With a stock rooted Nexus 5 (with 4.4.0) and OpenVPN Connect 1.1.12, this stopped working and that was really annoying.
Part of the issue was the one described here
But it was more complicated. It seems that there are routing table issues that I had to research a bunch.
Here are the iptables commands that I already had to run even on the Nexus 4 (with 4.3), which I got from here
Code:
iptables -t filter -F FORWARD
iptables -t nat -F POSTROUTING
iptables -t filter -I FORWARD -j ACCEPT
iptables -t nat -I POSTROUTING -j MASQUERADE
These (above) are somewhat liberal firewall rules that you may what to refine for more security.
But below are additional routing entries that I needed to add specifically for the Nexus 5 (with 4.4.0). They force tethered clients to route through the VPN, unless their traffic is a broadcast or designated for the wifi LAN. Those exceptions are required for DHCP to work on the tethered client. They assume the tethered LAN is 192.168.43.XYZ and the OpenVPN interface is tun0.
Code:
ip rule add from 192.168.43.0/24 lookup 61
ip route add default dev tun0 scope link table 61
ip route add 192.168.43.0/24 dev wlan0 scope link table 61
ip route add broadcast 255.255.255.255 dev wlan0 scope link table 61
This seems to all work best if I start OpenVPN after activating tethering, not before.
I'm not entirely clear whether this is a result of some change/bug in KitKat, or an incompatibility in "OpenVPN Connect", or both. I wonder if it would work ok with other OpenVPN clients like "OpenVPN for Android" (de.blinkt.openvpn)
Other Notes:
* Server is OpenVPN 2.3.2
* Server has this line set in its config:
Code:
push "redirect-gateway autolocal def1"
Running android 4.4.2 google stock image with SuperSU on LG Nexus 4. These routing commands worked great and allowed me to tunnel all WiFi tethered traffic through my VPN. Thanks for figuring this out it was bugging me!
Im stock 4.4.2 no root or anything just pure stock i download install openvpn from google play and imported my config files click connect then open PDAnet connect and the Ip is changed.
OK, so I'm having a bit of trouble understanding and implementing the fix for my nexus 5. I've already got WiFi tethering working through the sqlite db fix but now I can't get my connection to work when my VPN (PIA official app) is broadcasting. These commands you're sending, are they done on the phone terminal or computer and is that EXACTLY how theyre being entered. For rules in red where would I find the IP I would use. Thanks guys Id really appreciate any help given.
Worked!

Thanks scootley! These worked me on 4.3. I activated my hotspot before OpenVPN, but I used
Code:
iptables --flush
first before entering your commands. Seems to help. My OpenVPN server config also has the following in addition to push redirect:
Code:
push "dhcp-option DNS 8.8.8.8"
push "dhcp-option DNS 8.8.4.4"
push "redirect-gateway autolocal def1"

These commands are entered on the phone. You can download Terminal Emulator or something similar through the app store.
First make sure you're connect to your hotspot from your computer. Next, let's find your local IP address. Here are the instructions for Windows:
Click on the Start menu and type cmd. When you see the cmd applications in Start menu panel, click it or just press enter.
A command line window will open. Type ipconfig and press enter.
You'll see a bunch of information, but the line you want to look for is "IPv4 Address." The number across from that text is your local IP address.
Here's how to do the same thing on a Mac:
Open System Preferences (via the Apple menu at the top lefthand corner of your screen).
When System Preferences opens, click on the icon labeled Network.
You should see a few options on the left with labels like Wi-Fi, Ethernet, Bluetooth, etc. The ones with green dots have IP addresses assigned to them. Click the one on top (if it isn't already selected) and look to the right. There should be a sentence that reads something like "Wi-Fi is connected to Chocolate and has the IP address 192.168.1.102." The number at the end of that sentence is your local IP address.
Thanks for this thread, I've nearly got tethering working through Private Internet Access/Open VPN.
When running the commands
Code:
ip rule add from 192.168.43.0/24 lookup 61
ip route add default dev tun0 scope link table 61
ip route add 192.168.43.0/24 dev wlan0 scope link table 61
ip route add broadcast 255.255.255.255 dev wlan0 scope link table 61
i get an error "RTNETLINK answers: File exists"
I tethered up while connected to the VPN and could ping out to external IP addresses but no DNS resolution. So in my windows settings I manually specified DNS settings and can now browse the web through the VPN on my Galaxy s4!
But how do I fix the DNS issue? I want the clients that connect to pick up the DNS settings that actually work, without having to manually specify.
Thanks for any help

1) RTNETLINK answers: File exists
This just means you already ran the command before during this reboot session and it's saved into the route table. If you restart your phone, and run the commands again, it will go through first time, but repeated commands will yield same error. Should be normal. Table clears on reboot.
2) Please see the thread at http://forum.xda-developers.com/galaxy-s2/help/solved-wifi-hotspot-issue-samsung-t1689242
It seems like in order for OpenVPN DNS push to work, you have to change your APN settings on your phone to have it automatically register and push out to your other devices. I had the same problem and came across this during a search.
Massive thanks to the OP for posting this here and to everyone helping out in this thread.
The above rules route wifi tethered traffic via the vpn but I was wondering if there are similar rules to route usb tether too?
Cheers
It seems to work once, but when Data connection is lost or openvpn reconnects, wifi tathering stops working, need to do everything again (switch all off, connect to 3G, vpn, create wifi hotspot and apply fix script). And somehow DNS doesn't work. Tryed on Galaxy S5, LG L70, both on 4.4.2
But in general, this workaround is working, just needs a little bit of tweaking
This is fantastic.
For those of you using VPN on your phone as well, does it seem to stay connected? My VPN (OpenVPN) was flawless on 4.3 ... I mean smooth as ice with no disconnects.
When I upgraded to Kitkat, I wanted to immediately hide in a hole from embarrassment. Only after trying to connect and stay connected did I start to read around to check what the heck was going on. Biggest mistake ever. But then again, who would have thought right? I mean come on...who would have thought it would make using VPN a nightmare after an update that's suppose to be improved? Whatever...
Anyhow, lesson learned. Now I'm waiting desperately for someone to figure out how to downgrade from 4.4 back to 4.3 and/or to find a patch/fix for this issue so we don't have to run a script on every boot or reset.
At the end of the day, at least there is a solution thanks to folks like you. Kudos to the OP and everyone else who has contributed to the work around...for the time being lets hope...
:good:
For anyone interested, I played with the commands to have it work over a USB tether instead of Wifi. Why? Because my battery life stinks and this way my phone is charging also. What the heck. works great.
The only change was in the two spots where it has "wlan0" change them to "usb0". Another change was that the subnet of the USB connection is 192.168.42.0/24 (versus 192.168.43.0/24 on wifi). I get it working in this order:
1) reboot phone (to make sure to other lingering route tables are wiped out
2) turn off wifi
3) establish VPN connection
4) start USB tethering (and have your phone usb connected to your computer
5) After eveything is hooked up, open a terminal window, make sure you have superuser access (su) and execute the commands below. I just have them saved in a text file on my phone's sd card, copy them and just paste them all at once into the terminal window. Haven't figured out how to get this to run automatically using init.d (yet - assuming you can because upon phone reboot, I have to assuming that it will spit out errors because the tun0 and usb0 devices will not exist!)
iptables -t filter -F FORWARD
iptables -t nat -F POSTROUTING
iptables -t filter -I FORWARD -j ACCEPT
iptables -t nat -I POSTROUTING -j MASQUERADE
