[Q] VPN - Epic 4G Q&A, Help & Troubleshooting

I have a PPTP VPN into my home network but have had trouble connecting with my Epic. Does the epic currently support encrypted pptp vpns? If not, is that something that can be added to the EB13 kernel easily or would it be a complex addition?

I have EB13 with Froyo 2.2.1 and I AM able to connect a phone based PPTP VPN to our Watchguard Firewall at work, however I am unable to use PPTP passthrough with Wifi Tether 3.0 and have been unable to get my laptop to create a bluetooth modem that works properly so I'm unable to actually use the Epic as desired at this point. I hope they allow PPTP passthrough through wireless tether in the future.

Does anyone have VPN Connection running on 2.2

Title says it all.
All of the 2.2 roms and kernels I have tried will connect to the VPN but must screw up the routes as they shut off my data.
Does anyone have this running?
the only issue i have with "VPN Connections" is that is doesn't pass DNS traffic correctly. hence, i must connect via IP Addy not DNS name. other than that it works fine for me. i'm able to establish a vpn connection then use the WYSE rdc/vnc app to connect to my windows or linux servers ... connnectbot for shell access.
I've also been unable to connect to either a PPTP or IPSec VPN over my 3G connection since upgrading to the official release of 2.2 on my EVO 4G. The connection appears to be established just fine, and the VPN server shows that my VPN client is connected, but I cannot ping to or from the device, nor access any internal resources from it. This is a serious bummer considering that things worked fine under 2.1. Will test over WiFi when I get home. Can't test it at work since we're behind a proxy (which is another gripe I have with Android right now... seriously Google, no proxy configuration options?).
i feel i should clarify the name the application i'm using to establish a vpn tunnel is not the stock android vpn application.
it is called "VPN Connection" http://www.appbrain.com/app/org.codeandroid.vpnc_frontend

I have some interesting info regarding VPN behavior. With 2.1, of course, it did not work. Here's what I experienced: I rooted my 2.1 with Unrevoked (not a full root) and then I installed OMJ's (8/6?) Froyo and lo and behold, my encrypted PPTP VPN to a MS 2003 server was working perfectly. I assumed that 2.2 resolved the vpn issues. Since I thought 2.2 was a fix, I didn't hesitate to install another ROM. This time, though, I also did a NAND root and installed another 2.2 rom; whose, I don't remember. My VPN was gone. What I discovered was that I COULD connect to an unencrypted MS PPTP server, but still not my encrypted VPN server at work. So, here we are today. I'm running Vael-Pak non-sense rom and after I loaded it I had no vpn, but here's the thing...a couple of days ago I was poking around inside some of the Evo's networking files, I didn't change anything, I just opened them and looked at them with Text Editor, and since then my encrypted PPTP VPN has been working great. I'm very hesitant to reboot my phone because I fear that it won't work anymore. Right now I'm happy.
I'm trying in vain to get VPN connections working too. The only ROM that I had it working with no problems was Cyanogenmod's. All the others don't seem to have it supported in the kernel. Now I'm running a ROM based on the stock 2.2 but haven't found a fix yet.
I'm in the same boat - my pptp vpn worked fine in stock 2.1, but not in stock 2.2...

I can't get a pptp (haven't tried l2tp) to connect from my unrooted 2.2 evo with encryption enabled. I'm trying to connect to my server at home running winxp pro with the default winxp vpn server setup.
Works fine if you disable encryption. But what's the point if it's not encrypted, right? It works fine with encryption using a laptop or my old iphone3G. Seems to be a bug with android.
I'd like to know if someone finds a workaround.
This worked in 2.1 - froyo broke it

I am in the same boat. On CM6 VPN works flawlessly, but it is missing a lot, and kept crashing on me.
On every other ROM and kernel with tun.ko, it says it is connected but no connectivity.
AVA V6 is fast, good battery life, everything works (including hulu, and blockbuster) and very stable, but the only single thing I can't get working is Cisco VPN!!

I am curious, does anyone have VPN working on any Froyo ROM besides Cyanogen?
If so what Rom/kernel are you using?
Interesting observation last night - 4g was temporarily working in sf, and my pptp vpn worked over it. I turned off 4g and retested, pptp vpn didn't work over 3g...

[Q] Froyo and pptp VPN over 3G

Has anyone been able to reliably use PPTP VPN with Froyo? I cannot make a connection over 3G, but have no problem with WiFi.
Also, using the Incredible as a Hot Spot, a laptop also cannot connect to a PPTP VPN. However, USB tethered, the same laptop can use the Incredible as a wireless modem, and connect to the same VPN, with no trouble.
This makes me think the problem is in the Froyo linux TCP stack somewhere. Are there other VPN solutions that can connect from the Incredible with Froyo? I am rooted, and moderately Linux literate.
Thanks,
Jim

[Q] Wireless tether and vpn

Moved into a e4gt from an evo 4g last week. Love the phone but I am having an issue with wireless tether and accessing a vpn at a clients.
My evo worked perfectly with miui's baked in tether. Now with this e4gt I cannot get it to work. Here's what I have tried:
Blazer ROM and sprint hotspot - gets online, but 800 error on vpn
Blazer and wireless tether for root - laptop doesn't see the hotspot
Miui and baked tether - will not get online
Miui and Wireless tether for root - online, 800 error on vpn
Blend ROM and sprint hotspot - online. 800 error on vpn
The vpn does work, I can connect from my home network. Just wondering if there is anyone who has gotten a setup like this working. It seems to me that these hotspots are not allowing either the 1723 or GRE traffic. I have not seen any optoins to pass these through. I have seen the vpn setup on the phone and tried it, but it has not worked either.
Thanks for any help,
DAnono

[Q] Wifi Ad Hoc connection problem

I have been trying to connect my epic 4G to my laptop through ad hoc connection. I am on CM9 Beta3 and Windows 7 Ultimate. My Epic can detect the ad hoc connection created, but the connection only last for less than 1 second, then stuck in "obtaining IP Address..." while the laptop fails to gain network access (although already "connected").
Tried the WPA2 and WEP but fails.
Does anyone solved this issue?
I would like to use Splashtop using the ad hoc as the local network...
Nevermind...
I use COnnectify instead. Now I can operate my laptop from my Epic...

make sure you have encryption enabled in your settings. otherwise, someone will piggyback off of your connection.

Anyone use wifi tethering with android anyconnect?

I setup the anyconnect client on my phone which works great. I can access internal web pages, ssh to internal devices. Problem is that if I launch the anyconnect client on the phone, and then wifi tether my laptop to the phone, the phone will not forward the traffic from the tethered device to the Anyconnect VPN.
FWIW, Wifi Tethering works fine without the Anyconnect.
Running Task650's 4.2.2 rom and the Anyconnect for root users on the phone.

Same problem here. Any help would be appreciated!
it's probably a routing issue on the phone, but I haven't had a chance to look into it yet.

bump.
bump. I will look into this. But can't post my help until I make 10 posts and get the ability to post links
Its a setting set by your administrator
The issue:
You might already know this but your network admin configured the app to prevent sharing of the connection. This is a common measure to prevent breaches in security. Looking at the Cisco AnyConnect release notes:
Cisco has qualified the AnyConnect VPN client over a bluetooth or USB tethered Apple iPhone only. Network connectivity provided by other tethered devices should be verified with the AnyConnect VPN client before deployment.

The WorkAround
How AnyConnect works on the android is the same as on a computer, which is documented on SuperUser.
So what we have to do is either, export the VPN profile to another VPN app, or change the variable in memory that prevents tethering of the AnyConnect VPN session.
This can be done using (while it wasn't created for this purpose) Game Gardian
