Problem description: The incorrect interface is being used as the source interface for communication.
Problem details:
I am using Google Nexus 5 Android version: 4.4.2
My phone uses 3G connection for the internet with an ip address of 10.18.xx.xx.
I am then connecting to the Junos Pulse - ver 5.0.1.41777P.
Once successfully authenticated, I get the ip in the subnet of 172.16.xx.xx.
However, the traffic instead of sourcing from 172.16.xx.xx gets sourced from 10.18.xx.xx which is resulting in one way communication.
This is creating problem with through the firewalls and application issues.
Anyone experiencing similar issues and work-around.

My employer just purchased my group a set of WiFi Xooms, but our WiFi uses Juniper Odyssey to authenticate. Is there an Odyssey client available for Android? (I haven't been able to find one) Or is there a way to replicate the authentication process? I know it asks us for an RSA SecurID when we sign in on our laptops, but I can't get the Xoom to replicate this behavior.
Unfortunately, the only information regarding Android that I could find on Juniper's Knowledge Base is in regards to their Pulse VPN.
If all you're trying to do is connect to the internet, you could try setting up a computer that is connected to the network with internet connection sharing through a secondary ethernet adapter. Then you could use a wireless bridge to share the ICS-enabled connection to multiple XOOMs.
Having an issue using the built-in VPN. I can set up a PPTP VPN and connect, however, once connected I have no internet (no data). As soon as I disconnect, I have data. Did some searching around the web and noticed it was a know issue on Android, but wondering if others on the TF have the same issue?
When using a VPN it uses the gateway on the remote network. If that network requires a proxy server you won't have an internet connection. There are apps out there that let you set proxy settings, but thankfully Google is finally included the options natively in the 3.1 update. What I would really like them to do though is allow you to use your local gateway instead.
I have no problems using AceVPN www.acevpn.com with my TF using the builtin vpn client. My HTC Inspire also works great on there.
What is the built in VPN client you are speaking of?
I am looking for a VPN client i can use to log into my work network - I assume it doesn't have to be the same client as on my laptop?
I am going on holidays and only taking the TF - I want to be able to VPN into my work network if needed. ON the face of it I don't see how it would work since even if I VPN in the network is MS based so not sure how an Android client works on a MS based network - since I am not remoting into a machine with Windows - just VPNing into the network......so once I am in then what?
Hey Guys,
I need a little guidance from you.
I am developing an app that connects to a medical device(an RTOS) using a certain port over Androids Wi-Fi hotspot feature.
This is how the app works:
1) it has to find all connected network devices to the Phone.
2) ping and/or examine remote device/port to identify remote device.
3) if everything is fine get stuffs done using this connection.
I am facing problem with step 1, later steps are working fine.
My question is:
a) how do I find all Wi-Fi network devices connected to a phone?
I have read that we can connect up to 5 devices to a Wi-Fi hotspot. I can just ping 5 of them but knowing which IP address range is assigned to remote devices is important.
Since Wi-Fi works in a different layer, I cannot always rely on IP address. However given the fact that dnsmasq(andys own DHCP server) is always running, I came up with a possible solution.
Lookup arp cache in /proc. But its true that arp entries will timeout, which makes my solution unreliable at any given moment.
Here comes the other question,
b) can I ping Wi-Fi hotspot broadcast IP and wait for the remote devices to reply? I have read somewhere that network devices connected to Android hotspot won't reply back as expected, is it true?
I need to support general public who cannot root their device, so using /data is out of my option. Since I cannot re-design the remote RTOS device, sending beacon packets to Android is not an option too.
c) Is there any APIs that I can use directly?
Any help would be greatly appreciated.
how to find wi-fi hot spot connected devices??

Wifi Problem Solve
Hi buddy you can use wiifimanger class that call by Services class.
1)
WifiManager mWifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo mWifiInfo = mWifiManager.getConnectionInfo();
ConnectivityManager myConnManager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo myNetworkInfo = myConnManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
getDeviceIpAddress();
this can give you wifi connected device IpAddresses.
Hello,
I have a galaxy nexus running stock android 4.2.1 with a very peculiar problem. From time to time i have trouble accessing a certain website if i try from wifi or from mobile connection it doesn't matter. If i restart the device the website works without a problem. It was a very odd problem and kept bugging me so i tried to focus on finding the real cause. After a lot of try and error i managed to arrive at this situation:
I have at my disposal 3 different wifi networks (lets call the wifi-1,wifi-2,wifi-3) and mobile broadband connections.
after a reboot of the phone (just to have a clear state) if i connect to wifi-1,2 or mobile conn the website works OK. if i connecto to wifi-3 the site also works OK but then after i disconnect from wifi-3 and connect to any of the other wifi-1,wifi-2 or mobile conn it doesn't work anymore. If i connect to wifi-3 again it works fine on that network.
I've connected to the phone using connectbot and checked the ip address and different params. and i simply can't get a ping to that website. a similar website located in the same subnet but on a different IP still works.
So what could happen on the network layer on the phone to stop working the connection to a certain IP?
Where could i find some info about how to debug IP networking issues on android 4.2.x
PS: I control both the phone and the servers that i'm trying to reach and can't see any traffic coming from the phone on the server.
PS1: I couldn't reproduce the issue with android 4.2.2 only with 4.2.1 (i've also tested android 4.4.4 and couldn't reproduce) i've tested 2 different phones with 4.2.1 and the problem reproduces.
This seems like an issue of handshake and IP Negotiation on the phone. Please see what options you have in terms of DHCP and IPV6 Settings. Please also take a close look at the DHCP Lease time of WiFi-3.
Also Please post in Galaxy Nexus Q&A, Help & Troubleshooting so that the right experts for your device may be of help.
Thank you

IPv6 is disabled
DHCP is similarly configured on all networks. different IP classes. IP addresses change correctly every time. As i'm able to connect to everything i try except that certain website i don't think it's something related with dhcp.
