I've had my Verizon Fascinate since launch day, and I really love it. Aside from the slow roll-out of stock Froyo.... Anyway I am trying to setup a VPN from my Fascinate to my home network. I've tried using the built in Windows XP PPTP, which works fine with my G1 running Cyanogen, but after about 30-45 seconds, the Fascinate says it could not connect.
If I pull up the Event Viewer for System on the windows machine, I get a warning every time I try (and fail) to connect.
"The user connected to port VPN4-1 has been disconnected because the authentication process did not complete within the required amount of time."
This fails whether or not I'm on 3g or my own Wifi. I've not sure whats going wrong, and there's only 5 threads in the Fascinate forum related to VPN which aren't related to this issue.
Is PPTP broken on the Fascinate? Has anyone managed to get it to connect at all?
Thanks!
(I'm running my Fascinate stock, no root, only thing I've done is the OTA update a few months back)
I know your pain, I tried getting the built-in vpn client to roll but it gave me the same error message that you got. I tried "1 VPN" from the market and it worked and I was able to ping another pc on my network thru Windows PPTP server. But for my purpose I was unable to mount a Samba share over VPN

Thanks for the recommendation, I went ahead and downloaded the free trial APK from their website for "1 VPN" and tested it on my G1 (which works with the stock VPN) and it works fine. I side-loaded it on my Fascinate and tried the same credentials (verified with the G1) and got the same error.
Am I missing something here?
I updated to DL09 and this issue is continuing. However I no longer get the errors in the Windows event viewer as I did before. I am still able to connect to the VPN via my G1 with Cyanogen. When I successfully connect via my G1 I get an event message. When I attempt and fail with my Fascinate no error or message is logged. Any ideas?

Anyone try using a PPTP VPN and get it working? My linux laptop and old iphone 3g connect fine to this end point, but the Epic fails almost immediately. Ideas?
Thanks
Actually, I tried this myself and had it fail as well (although I couldn't test it with another client ie my laptop at the time). I've also had many other problems getting more than a few other applications to connect: (see this thread: http://forum.xda-developers.com/showthread.php?t=775836)
I'm seriously thinking there is some firewalling/port blocking that was built into this phone. I wouldn't say it's built into the networks because both sprint and clear connections exhibit exact same applications not working (ports blocked?) and thus I'd guess port blocking in the config files of the phone. I'll research the issue more in depth after I get my phone exchanged first (gotta take it back and rebuy it to get my 2 year discount :\ don't wanna root before)
My Xoom usually disconnects the VPN immediately after opening any file from an SMB Share using ES File Explorer. I preferred Astro but the SMB addon doesn't work with Honeycomb yet. A variation of different vpn clients all do the same, as soon as data is done being transferred from a single download, the VPN will disconnect.
Is there a workaround for this? It would be great to only have the VPN connect when resources on the network were accessed or written.
I haven't found a workaround or solution to keep the VPN up and stable.
(btw, this is a typical MS 2008 PPTP on a Windows Domain)
At the moment, I'm having to reconnect after every file transfer- again, the wireless network doesn't seem to make a difference (although the 3g connection is obviously poor)
I've done a little troubleshooting on this in the last few days using the magic of wireshark. MS PPTP Server, makes the connection and then drops after SMB traffic is attempted, as well any website will not load, and no email / communication will work.
I believe this fully involves a Default Gateway setting on the Xoom, being it's a client-side setting and the Xoom doesn't appear allow that option to be changed (silly that it's missing, imo).
When I make a connection, Verizon's firewall policies see a foreign IP return traffic at some point on their network and blocks the transmission completely, eventually causing PPTP to timeout.
Here's a good read on how to get around the restriction:

I myself have been on the phone this morning regarding this issue, I'm up to about a 3rd level of tech support and he is trying to tell me 'nothing is blocked at all on the Verizon network'...
I'm awaiting a call back now... at which I'll try to show him the above site/resource and maybe he'll move me to an unrestricted IP block. We bought 3 Xooms with the intention of working remotely in the field using PPTP- 4 more coming soon---
At this point, I'm still tempted to go back to Sprint and just wait on their Xoom release.
*btw, you can verify the above by tethering to the Xoom and changing your default gateway on a laptop/pc, the connection will work fine.

AH-HAH!

Apparently this is a known issue.
Encrypted PPTP is broken on Android: http://code.google.com/p/android/issues/detail?id=4706
I've posted about this problem in this thread:
http://forum.xda-developers.com/showthread.php?t=992876
I've tried it on every version of Android since 2.1. I tried it with my Xoom on 3.0 and the problem remains. It appears to be a pretty low priority for Google.

Turned off encryption on the server and all was well. I can't believe google let that slide... !?
I guess I'll transition to a L2TP VPN...
I just picked up my wifi only Xoom today, and discovered that it appears to have an issue that's virtually identical to one that the Thunderbolt shipped with as well: I simply cannot make L2TP over IPSec connections. In fact, judging by the logs on the server, the VPN client in Honeycomb does not even try to connect. Checking the server side logs shows no entries whatsoever. However, if I go back to my Thunderbolt (which now, being rooted and on a different ROM, will work) I can connect to the same VPN, with the same settings, with no issues. But when I try from the Xoom, all I get is "Unable to connect to the network. Do you want to try again?"
However, I can establish a PPTP connection from the Xoom without any problem (which is, again, exactly the behavior that my Thunderbolt exhibited until I was able to go to a new ROM), BUT, once the connection is established, the Xoom behaves as though it has NO internet connection whatsoever.
I would REALLY appreciate help with this. Thanks
Thats odd. I have had no issues with L2TP and IPSec. Works slow for sure but was working fine. I was on wifi at home. When I tried via 3g it was ungodly slow, took like 5 attempts to connect. Any info would be nice

Hey, I was hoping I could get some help with this. I must be doing something wrong because I've spent a ridiculous amount of time on this project and have nothing to show for it.
I want to run a mobile hotspot on my phone, but not nearly enough to justify paying Verizon an extra $30/month for tethering. I'd only use it a few times a month and wouldn't push a lot of data thru, plus I'm paying them for an "unlimited" data plan - I won't get into that, you know where I'm coming from. I know they probably won't do anything about it since I'm using it so little, but I want to add an extra layer of security via an SSH tunnel or a VPN. I'm sure they just have to run a very basic report on their system to catch somebody who's tethering, and who knows when some manager will tell them to run it on every user vs just the high bandwidth ones? They could force me onto a more expensive plan, disable my account, throttle my connection, or just block any port an Android phone doesn't normally use, and they could do all that automatically pretty easily. If all my tethering data is encrypted they'd have to do some actual work to prove I'm tethering and probably won't think it's worth their time.
I installed OpenSSH on my home PC, forwarded some ports, and put the SSHTunnel app on my phone and it works great. It seamlessly moves all traffic over my SSH tunnel, except for the mobile hotspot. Which was kind of the point of the whole exercise! I looked all over the place but could not find a way to resolve this.
Next I looked at setting up a VPN so I loaded TomatoVPN on my router. The default VPN (OpenVPN) option for that firmware is IPSec with a CA certificate, so I went about setting that up. Apparently the default Android VPN client doesn't work well with IPSec because I can't get it to work - it keeps prompting me for a username and password, but it won't accept my router's admin credentials. None of the tutorials mention that prompt and I can't get around it. I messed around with an IPSec PSK VPN but couldn't get Android to connect to that either.
I looked into PPTP a bit but they say it's not supported by Linksys or OpenWRT, and from my experience Tomato doesn't appear to work with it either. I was going to put a PPTP server on my PC but saw somewhere that many routers can't forward PPTP requests from a WAN into the LAN.
So I went back to the IPSec approach, figuring the problem is with the Android client. I tried putting OpenVPN on my phone, but got stuck where I have to register a tun.ko file using the terminal. I don't even know if I found the right tun.ko. Then I realized I was trying to install an app to configure an app that installs another app and maybe I wasn't going about this the right way.
Does anybody have any advice? How should I approach this?
Here's what I'm using
Phone: Rooted HTC Thunderbolt
Carrier: Verizon
Ugh, looks like Verizon is 1 step ahead of me:

Well, that sucks.
I use Cactus VPN to connect to their NL server to watch NFL games using Gamepass over PPTP. I have been able to connect just fine and it will work for a brief time. But as soon as I go to a website, it will begin to load the site for a second or two and then loading stops and times out. Once that happens I can't even ping anything. Kill the VPN connection and it goes just fine. The VPN worked with stock ROM and it works in Win7. I also connected successfully on my daughter's Macbook. It seems isolated to this release on AOKP on my N7. Anyone else had this problem or know a fix? I love the ROM, but with VPN not working for me, its a no-go.
