PPTP VPN connection issue over 3G - AT&T Samsung Galaxy S II SGH-I777

I am having problem connecting VPN over AT&T's 3G network. It will log-in and get IP address from VPN server. VPN server shows it is logged in. Connection stays connected.
However, I cannot access any resources over VPN connection. Cannot even get into router. (I'm running VPN server in my router running DD-WRT).
Tried pinging router from terminal, no response.
It works perfectly when I'm connected using Wi-Fi.
Any idea what is the problem and how to fix?

No one using VPN??

hd2 wifi router dns problem

Hi,
I have a strange problem with WiFi Router on my HD2. When the device is connected to internet via 3G or HSDPA and is forwarding the connection to WiFi everything is fine, but when the connection changes to EDGE or GPRS I'm not able to use DNS from the laptop connected via WiFi - I can ping some host using it's IP, but there is no way to resolve the domain name.
The HD2 on its own works fine via EDGE.
(I'm using Orange in Poland)
Anybody had similar problems? Any solutions?

[Q] OSX lion l2tp VPN server connection

Posted here, since I believe this is a general and not device specific issue.
So, I have set up a VPN server on OSX Lion Server edition.
It is using l2tp with preshared key and username/password for login.
i(beep) works fine and connects. Laptop works fine and can connect.
But...
1. When Iam on local network (same IP segment) I can connect using Android native l2tp VPN connection setup with PSK and user/pass.
2. When I try to connect from external (3G or other WiFi net) I am unable to connect.
3. When I enabe native tether on Android device, and connect i(beep) to the Android AP, I still am able to connect from i(beep).
These three steps tells me it is not a carrier issue, and possibly an Android issue.
Did anyone experience this (and even better.....did you find a solution)?
Kinda like the l2tp connection for security, and also Lion natively does not supply pptp connection.

I am trying to do the same thing, I havent got the VPN to function yet though but I think its a router issue among other things. I bought a domain name and I am using that with dyndns to help simplify the ip change issues... I am getting a new router to test here next week so hopefully I'll have a better idea.
However now I am worried I'll run into the same issue as you!! lol... Its been a while since you posted, have you found a solution yet?
No. Didn't find a solution, but you might be correct in assuming its a router issue. Have a Netgear myself, and those have had quite a few issues.

I ended up getting a new Airport and it has pretty cool setup integration with the Server / Airport Utility, however I still cannot connect with the VPN connection.
My initial reason to set this up was to use PLEX... AND this actually works very well if I setup my connection through the PLEX connection settings.. but I still can't get it to work with the Android VPN setup.... (tested 3G and WiFi)
..also I cannot get the VPN to work with a Windows PC... tested a Mac (hackintosh) and it worked instantly...
so I think its a Mac thing maybe... Since PLEX is working... I am happy but would still like to get the VPN connection working properly. I suspect I'll need to call Apple about it though
I am also have a similar issue.
OSX Server running 10.6.8
L2TP VPN and PPTP services running
My iPhone and laptop can connect just fine. My HTC One X and HP Touchpad (CM9) can not. Both say the address can not be resolved. The server is sitting in the DMZ and if I enable the web server both devices can resolve to the default welcome page just fine.
1. It isn't a DNS issues since they can connect via the web
2. It isn't a port issue since other clients can connect
Is there some dumb setting i am missing in the VPN setup?
Thanks

OSX Lion Server L2TP VPN and ICS not working
Hey guys.. I got PPTP to work to OSX Lion Server by making sure PPTP, L2TP, and IPSec forwarding were enabled through my router.
Also, make sure to check the VPN logs in /var/log/ppp/vpnd.log to see why it's not connecting..

Openvpn connected but not tunneling over VPN

Hi,
I followed several guides on connecting my Galaxy Ace with an Openvpn Server.
I finally managed to connect to a Openvpn server using Certificates with the latest Cyanogen Mod for the Galaxy Ace.
For the Connection I used OpenVPN Settings App from the Market.
The thing is that the connection is established and I see in the config, that VPN is connected. It displays the message:" Connected to 134.x.x.x as 192.168.200.100"
But unfortunately nothing is tunneled over this VPN connection. If I for example check my external IP on the Galaxy device, it still shows me my G3 Provider IP. But I expect to see the IP of my Home Internet Provider. Furthermore no connections to devices on the local Network of the VPN Server can be made.
That means, that despite the VPN Dialog showing me that I am connected to the Open VPN server, no connection is tunneled over that device.
The Guides I used to setup the VPN Connection are from here:
freetz.org/wiki/packages/openvpn
and
riseup.net/en/openvpn-android
If I connect with the same settings from an windows PC to the Server, The connection is established and tunneling just fine.
Anyone knows what I am doing wrong?

[Q] SSH Tunnel - works on WiFi, not on 3G?

I've searched high and low for this, but I can't find an answer.
I am using the SSH Tunnel app on a rooted HTC One S which is otherwise stock. It works perfectly on my home wifi network (if I access an ip web page it shows my SSH server's ip).
If I then turn off the tunnel, disconnect from wifi, reconnect over 3g it connects fine, but when I access the same site it shows my phone's IP, not my servers.
Are there any known issues that prevent SSH Tunnel from working on 3G?
Any suggestions?

[Q] Wi-Fi issue connecting to WPA network

My Rezound has issues connecting to my WI-Fi network at work. It's an 802.11g network using WPA/WPA2 encryption. My Rezound seems to be the only device that I can't get to work on it. When I enter the password to the network, it does connect and obtain an IP. However, it then has no internet connectivity. It works fine on my WI-Fi at home though. Any ideas?
Also, I updated the firmware on my router also, and didn't help.
