Hello,
I have set up a vpn server at home, trying to connect to my share drives.
Server is ubuntu server 10.04.1, using pptpd. I have verified settings and i cannot connect w/ my nexus one running cm6r3. Anyone have any luck w/ the built in vpn tool .
I keep getting GRE: Bad checksum
Usually indicated username/password failure, but i know it is correct
Also does it use CHAP or what type of authentication?
Thank you.

Hello all:
(first of all, I apologize for the double post, I erred and replied to a thread in the diamond forum)
I'm having problems getting my remote desktop to work. Been trying to connect since I picked up my Fuze on the 11th.
I have three different computers that I can successfully administer via my desktop. I've tried using 3G to connect, no success. I've tried using Wi-fi to connect, no success. I've used local computer names, IP addresses, properly forwarded ports --
It has to be a setting I'm missing on the phone. Any ideas? TIA
What version of Windows are you trying to connect to? Do you have a Firewall? And have you done the port forwarding on the router?
But the only options you need is Computer: IP Address and the user name and password. Use a Domain if you are connecting to PCs on a domain. Also when I logged in not using 16bit color under options the PC was almost unusable.
My attempts
The things I have tried since my post:
1) attempting to connect to Windows Server 2003 machine, non-local. Used IP address with port, same IPort that works from my desktop. Left username/password blank -- filled them both in -- left the domain name blank -- filled it in. All failed. Get the error message with three possible causes listed. Connected to my home network via wifi, data connection disabled (sometimes causes problems with my internet browsing if they're both enabled)
2) attempted to connect to a local machine, running XP Pro. Again, tried all possible combinations of username/password completeness, no success. Using Wifi
My local router does have a firewall, and the remote router does as well. I can successfully navigate those using my desktop (or laptop, for that matter)
GTO: I appreciate the quick reply...thank you.

Okay its been awhile since I used 2k3 sever. Using 2k8 lately but are you trying to use Terminal Server? and if your using 2k3 and you have ISA enabled I know it can be a pain to do port forwarding with it. But let me get this stright. You have no issues using XPs Remote Desktop to log into the server machines Terminal Server/Remote Desktop? Here is an idea. Whatever port your running Terminal Server/Remote Desktop type the IP Address with a : and port. IE 192.168.0.1:3000
Also if you would like you can PM the IP address of one of the Machines and I will try from my phone that I know is working with my machine. I am pretty sure you don't need to end a user name or password and it will bring me up to the login screen or you can make a temp account. On also on the Win2k3 machine I am pretty sure you have to add the option to login with Terminal Server even if its the Administrator account.
I am able to connect to my local XP machine over wifi using the ip addy/no port. Hostname (DNS) connection attempt failed, though. My 2k3 server's power supply died or I would test that for you.
No special router config (port fwd) for my device had been done.
The fact that you can't get to your local box on your local network is where I'd start.
Local Network Issues
Thanks again to you both...
I think that might be the problem -- the local network setup. I can connect via wifi, and browse the web. However, I can't install a network printer using the WinMo app that's included, and I can't seem get to the local PC even when I use the local IP instead of the DNS name. I did check, I'm being issued an IP address by the router (obviously), but still no dice on anything relating to network based traffic.
Is there a way to ping using WinMo? I'd like to be able to use that start.
Cont..
Also, I've noticed that I don't get the same error each time. Depending on which machine I'm trying to connect to, it'll give me an error with either two or three options as to why it's not working. Trying to figure out what that's telling me.
As far as Terminal Services are concerned, when I connect from the desktop, I believe I'm using Remote Desktop there (honestly, I haven't been paying attention -- I just use whatever pops up when I type 'mstsc' from the Run dialog, lol), and I can connect to the 2003 server. However, I can't play with this anymore today, because apparently the server is down, and I won't be able to get to it till Monday.
I think I'm going to go play with the ATT proxy and see if that changes anything. I think mine is still enabled because I read that it might help with the GPS problems...
I have found some freeware app... pocketping 1.6 and microsoft has a network tool offering which I am not sure will work on WM6. I have no exp. with either tool on WM.
Can you get to your http/https router mgmt interface from the device? Check your router's client table? Does your router have any logging capabilities?
Sorry, more questions than answers.
Router
I am able to "dial" into the router from my phone -- it shows the HTCP4600 in the clients table with an IP of 192.168.2.108 ... all good.
My logging on the router was disabled, but now it is enabled. What should I be looking for?
I think i'll try the pocketping...
Now make sure inside of the router then you have all the correct ports forwarded.
It should be port 3999 to 3999 On UDP and TCP and then your PC ip behind the firewall.
Pocketping, JETCET Print 5, and success
Here's the update:
Discovered that by disabling the AT&T proxy on the Fuze, I was finally able to connect to my network printer -- the Fuze doesn't have the drivers for my printer, but that's another thread.
So I was able to make my first IN-Network contact. Installed pocketping 1.6, and it's a very useful tool. I'm able to successfully ping the computers on my network now that the proxy is disabled -- an voila...I can also connect to my laptop on my own network! The main trick was to use the network IP address and not the DNS name.
Thanks to both of you who helped out.
Has anyone ever attempted to set up a WinMo VPN to a Sonicwall firewall? I've been spinning my wheels for a few days now trying to get it to work on my TP2 with no luck.
I've not connected to Sonicwall, but I too wasted a lot of time trying to connect to our corporate VPN server (uses PPTP). The phone couldn't connect--wouldn't even attempt to connect.
I then installed another modem connection in my work connections. I used the #777, [email protected], and password = vzw. It works now.
Maybe that will also work with the Sonicwall. I'm curious why I had to go through all those steps. My other Windows Mobile phones automatically used the Verizon connection when a VPN session need to be established.
Thanks, but I can't use PPTP. I need to use IPSec or L2TP. My issues are more about properly configuring one of these protocols. Anyone? Anyone?

how about netextender?
So my school just got net books for everyone and also WiFi, but the problem is that my android phone can connect but it cant use it. at first i thought they somehow banned everything but the net books but when i brought my laptop it connected just fine:. so what do you think they did. do you think it could be the mac?
p.s. i can only use internet explorer on my laptop and not firefox.
Just found out that i am in the wrong sub forum can an awesome mod move for me? thanks
It depends of a lot of settings.
What is the encryption mode used on this network? (open, WEP, WPA, WPA2-TKIP, WPA2-AES)
Is the laptop owned or managed by the establishment? (ie: is it registered on an Active Directory domain?)
Is it using an enterprise authentication method (ie: 802.1x)?
If so, which authentication type is it using (ie: TTLS, PEAP) and the inner authentication protocol (ie: MS-CHAPv2, GTC)?
You might have to put your network credentials in order to connect to the wireless if they are using 802.1x.
For your Firefox issue, maybe you could try setting it to use your Internet Explorer's proxy settings and see if that fix the problem.
Something similar happens to me at work, but in this case they are using an automatic configuration scrip to connect to the web.
How can I use the configuration script in my android device

You cannot. Find out the proxy address and port and download something like TransProxy.
I have a New Asus Transformer Pad with 4.0.3 on it.
I've added a new VPN IPSEC XAuth PSK to it and it connects fine but when I start the VPN then try to browse the net its reboots and if I try to access email it can't see anything.
I need to know if this is a bug or if something is configured wrong.
I've tried looking everywhere to find this out but can't find anyone that's had this problem so far.
I set up VPN on mine using IPSEC XAuth PSK, it says it connects, but I can't do anything (like remote into a PC). It doesn't crash though.
When I asked my Administrator to look, he could see the connection but there was no data coming through at all.
I've rooted mine and used VPN Widget which I used on my DHD and it works fine.
Update
Asus has since released and update but i'm not sure what it corrected. The version number hasn't changed so it must just be some backend fixes.
When i connect the VPN now it doesn't crash but as you said it doesn't look like its pushing the data over the VPN connection. The stats never change.
I've tried putting in the DNS search name, DNS server. That didn't help.
The forwarding route might help but i'm unsure what route i should be putting in there any ideas?
I'm a system/network administrator, if possible I'll see if I can try and set it up for myself and see if I can replicate the bug (if I can't it's probable that it's a misconfiguration on your end).
Might take a while though
Settings
I'm using a IPSEC XAuth PSK for the VPN connection.
Hopefully this will be able to give you the same results.
Same Issue w Asus, but not Acer
I have been waiting for a while to have this resolved as I want to be able to use my Transformer Prime to vpn to my work. My IPSEC XAUTH PSK connects as well, but will not allow me to remote desktop into my work PC.
I bought an Acer A500 for my daughter and this morning I was able to update it to ICS. Tried the exact same VPN settings, connected and remoted into my work PC flawlessly.
Looking forward to the next firmware update for ICS / Transformer Prime so it hopefully resolves the issues.
Found a VPN that works
So that people know I found a VPN that works with PSK X/Auth.
Its pretty new made by Matthias Meier called VpnCilla.
There is a trial to test with but you then have to buy it for $5.46.
Try it out it works.
As an alternative, you can set up a pptp vpn using the vpn setup wizard in windows 7 for free (assuming you have windows 7). I can confirm that this works with the 300. It uses microsoft point to point 128bit encryption, and can be configured to require password encryption. Its not exactly high end encryption, but its better than no encryption or novpn connection at all. It will protect you from some kiddie running a packet sniffer program.
I want to connect my android device (nexus 7 2013) to an openvpn server which is not administrated by me, meaning I have no access on the configuration.
On my windows7-pc, I do this with the windows version of openvpn, the provided settings file for the openvpn server and the also provided pem-certificate.
Since the server uses the tap device of openvpn, alternative clients like openvpn for android by arne schwabe[1] don't work (this app doesn't support tap).
Since I don't have a private key file (*.key), I cannot generate a p12-file[2] which could be imported by the official openvpn app[3].
The pem-fileformat is compatible to *.cer and *.crt, meaning, I can simply change the file extension to "convert" them. The crt-file can be imported by the android systems (security -> import), but this doesn't help openvpn as it seems to only use it's own certificates.
Any suggestions on how to achieve a successful connection?

wifi
i think if you have ICS_P740AV1.0.0B07 + you can't find open hot spot and if you can see you can't connect.
Try to make one hostop secured with wpa2 and try it.

Whoa, i only understand half of it
I have android 4.3 JSS15Q rooted with flo (?). I have superSU and Busybox installed. I followed the default instructions of the nexus root toolkit. My wifi is connected for sure, but it has blocked ports (which is the reason for all this). However, since I'm failing at an earlier stage, and, since it works from my pc from the same network with the same openvpn on the same ports I suppose the error is not in the network settings...
The wifi i'm connected to has wpa2+pkip etc. but I'm not sure how this is relevant...
rom
you have installed a custom rom?
you have try to enable and disable airplane mode?
you have data conenction?

I have stock android rooted. I only have wifi and the connection works perfectly, I tried rebooting the device, I consider this counts as "dis/enable airplane mode". I have good wifi signal strength.
I have no issues accessing websites over port 80/443, only the blocked ports don't work. The openvpn server is reachable on port 443 (it works from my pc).
Hello,
did you ever manage to solve this? I'm looking to configure my nexus 7 2013 to connect to an OpenVPN server using TAP and it doesn't seem to be working. I'm using OpenVPN settings with certificate-based authentification. I'm able to connect to my server, however I don't get a local IP address assigned and when I browse the internet, my IP is still showing up as from the original connection instead of the VPN endpoint. Computers with windows 7 can connect to the server no-problem and all their traffic is directed to the tunnel. Any ideas for guides and walkthroughs?
Thanks. Any help is very much appreciated.
