vpn connection (pptp) disconnects

I want to use PPTP vpn connection to my work together with Remote Desktop (Teminal Service) application.
The PPTP vpn connection is established successfully.
From my work PC I can ping the pptp ip address of my PPC.
However if I switch to an application which would generate internet traffic (such as terminal services, internet explorer) my PPTP connection drops.
On my vpn server I get the logs and see the disconnect reason as "user requested)
What is the problem ?
Thanks...

hi,
I guess nobody has such experience with vpn connections.
where can I find information about this problem ?
thanks

Hi, I have the same problem more or less
see http://forum.xda-developers.com/showthread.php?t=291208

I have the same problem when trying to use Skype. My office also requires the use of a VPN (PPTP) when connecting via the wifi.
Skype connects, I can make calls, but the connection is dropped after 30s (the VPN is closed). Oddly enough, it I have the impression I prevent the VPN connection from dropping by using Pocket Internet Explorer at the same time (I have tried creating a website that automatically refreshes every 10s, but this didn't keep the VPN open). The Messaging client als shows odd VPN behaviour: it always closes the VPN, and opens it every time send/receive is selected.
I suspect not all programs keep the VPN open, even despite the fact that those programs are generating traffic over the connection.
Any hints or suggestions are greatly appreciated!

(sorry, I can't edit posts in Opera Mini)
MarsRover: I have changed the AlwaysOn registry setting in the registry (in the folder of my work vpn). Ii appears to have changed the Messaging behaviour (but I need further testing to be sure). Tomorrow I'll see if it changed the Skype connection.
Thanks for the suggestion, if it works it ought to be put in the FAQ.

Hi,
MarsRover,
I couldn't understand the solution. Can you explain ?
My situation is :
I am using Wifi connection to access internet. This connection is selected as my internet connection.
My pptp vpn connection is set under my Work connection.
So when I use the pptp connection I connect to Work over Internet.
But then it gets dropped if I open internet explorer.
If I set "*/*" to my intranet addresses, I have to connect to everywhere over my VPN connection. This is not good because I don't want to use VPN connection for Web browsing etc.
There must be another way ? Don't you think so ?
Btw, if I set AlwaysOn to "1" in registry , and then check it back after a connection is made, I see it is "0" again.

Hi
You do not have to redirect all traffic through the VPN you can pick and choose under settings>connections>advanced>exceptions just add the urls you need. ie so instead of */* use the specfic range ie 10.0.0.*/* or whatever range your work uses. One more issue however if the wirless ip range overlaps the internal VPN work range you may still have isssues. ie if your wireless ip address range is 10.0.0.x and your vpn range is 10.0.0.x then even if you add 10.0.0.*/* in the exceptions it may still try the wireless link rather than the vpn link for your TS etc. If you get my drift. There is a discussion on this here:
http://forum.xda-developers.com/archive/index.php/t-217422.html

Thank you Stephen.
In fact, I am aware of how the exception list works. I can add the IP addresses which I want to reach via work vpn.
However, I still wish that there was a way to use VPN connection manually without using an exception list.
Isn't this possible ?

This is good for me because I DO WANT to use VPN for all network access.

hello...
i haven't a clue if this helps...
in my firm theres a cisco vpn connection... i search a long time for a programm that i can use with that vpn connection...

where can I find it ?
does it connect to cisco vpn concentrator / ASA ?
there is also AnthaVPN from AnthaSoft but it's not very reliable.

PPTP
Bluefire seems to work fine with IPSec, but I need PPTP (IPSec requires NAT-T in most cases with GPRS/3G).

vpn client?

hey guys,
am trying to connect to my office's VPN with my vario II. the default software provided does not seem sufficient. for one, i have one of those security key ring things which means my password changes every time i want to connect.
my pc uses cisco's vpn client...
any ideas? right now i'm just synching my exchange server with my pda using activesync, but wouldnt' midn having it on the go! there's no "external" access as such for the exchange server - it does have a web front end but its highly customized and isn't as easy as just configuring it as an external data source on my pda...

This one works perfect for me..
http://www.ncp.de/english/download/testsoftware/index.html

We use AnthaVPN at my university and it's supposed to work quite well with Cisco concentrator gateways, but be warned, if you have the latest 3.3 aku, you might run into problems like I did regarding loosing 3g internet connectivity on your hermes. However it could have just been a fluke as I didn't bother trying a fresh install of antha after a hard reset or anything since 3g is just as fast as my universities wireless internet anyways
Hope this helps

You can also try Bluefire. They have a 30 day fully functional trial version.

I have installed this but can't see any way of configuring the VPN connection. How did you configure it?

You have to use the PC client in order to create a configuration file and then transfer the file to your device

duh!
thanks!

bluefire is amazing. i bought it.

I came close to getting bluefire to work on our Cisco network... But once connected it would not transfer data.
I read on a seperate post here that alledgely the medianet unlimited plan uses the wap.cingular access point. That point is NAT based and some vpn clients do not like that... So they refuse the connection based on changing ip addresses.
I am not a networking expert so I do not know if this is in fact the case.
I do know I tried every freakin setting for bluefile and could not get a vpn tunnel from my phone to our Cisco vpn... So I gave up!

NCP
Could I get more specific infos about bluefire? They wanted a 5 page survey before they would send me a (business) trial.
Well, NCP Secure Entry VPN Client works perfect for me with Lancom and other standard firewalls. And yes, configuration is made with a Win XP Desktop Application. Nice about this: They got a Desktop VPN client as well which will be configured exactly the same way. So if you got a working setting for your Laptop you can manually copy the settings and they will work on the PPC as well - thats what I did.

How to configure a (free) VPN?... as it's possible with IPhone

Hi Leo users,
I would like to configure my Leo so as to use a VPN.
With my Laptop, I use a free VPN that we can find at http://www.itshidden.com.
And it works fine for surf. at home or on publicWiFi...
My problem is that I try and try to configure it on my Leo, but it's not working.
I saw a tutorial on IPhone3 and it seems to work !!! and it works on one XP computer and another one on Vista.
We can find an explanation "How to" for Windows XP at : http://www.itshidden.com/Support/VPNXP.html
We can find an explanation (in french, sorry) for IPhone3 at the end of http://free.korben.info/index.php/Configuration_d'une_connexion_PPTP_(VPN)#Sous_un_OS_mobile .
Please, would you like to explain me how to configure?

just some precision on what I do, and what can be done...
With Leo :
I select "Comm Manager"/Menu/Connexions
then "new VPN connexion"
Name : My VPN
Host Name: vpn.itshidden.com
User Name : my_login
password : my_password
Domain : -nil-
the pictures for Leo:
With Iphone :
Settings/Network/VPN
select for a new one
"PPTP" protocole
Description : My VPN
Server : vpn.itshidden.com
Account : my_login
password : my_password
and that's all.
pictures for IPhone :
So, I'm sure that it can be done on our Leo as it seems very simple on IPhone... but I'm not able to do it.
Please, may I have your help.

you can use a proxycab program to do it for you

Hi civilization,
thanks for your answer.
I'm not sure to well understand.
I think "proxycab" is to use a proxy...
if it's that, this is not exactly what I expect because a proxy doesn't encrypt data as VPN do.
I want to use a VPN because public Network (or Network of a competitor) are not safe.
It's really easy to configure a VPN connexion on a XP or Vista laptop, but hard (for me) to configure it on Leo.

Hi all VPNers
I have unfortunate and official information for anyone hoping to use PPTP VPN connections. Apparently Microsoft implementation of MPPE is not compatible with microsoft's very own mobile OS...shocking.
A supplier who was dealing with MS told me:

> does, but it doesn't right now, and I think we're going to remove the

>
> Windows Mobile 6 doesn't actually support the encryption part of the

> support Microsoft's own encryption protocol. That's why you're
> getting disconnected immediately when you try to browse.

LT2P/IPSEC work perfectly with WinMo 6+ however.
There are 2 ways around this:
1: Find a software client that works with Windows Mobile and supports PP2P MPPE (none exist that I am aware of)
2: Find a VPN supplier who will provide you with LT2P connections. Though in my experience those are quite rare and expensive

Hi jagnet,
Arghhh
like in your signature, I hope I might say "I reject your reality and substitute my own"...
but what you answer is incredible.
it's so easy to configure a VPN (PPTP) in a laptop (OS Windows, or Ubuntu, or Mac OS X), or a mobile like IPhone OS 3.
I can't imagine that it's not possible in our Windows Mobile 6.5 as we have an option to choose between IPSec/L2TP and PPTP !!!
see :
Arghhhh, Windows kill me.
did you find another solution, not too expensive?

have tried surfing the web on 3G network?

Yes you can select PPTP in WinMo but it still won't allow any data to pass on a PPTP connection with MPPE (i.e. 99% of routers, services and providers) A major oversight at the Windows Mobile Developers Lab.
Aaaaanyhow, I found perhaps a complex but free method which works if your don't mind some of your connection being insecure.
1: You'll need a spare server (I have too many at home )
2: Set that server up to act as a proxy
3: Set that server to connect to your VPN Provider
4: Setup your phone to use your Server as a Proxy
5: All data will then pass onto your proxy which will pass on to the VPN.
Another much more secure, though complex method is:
1: You'll need a spare server
2: Set that server up to act as a L2TP SERVER
3: Set that server to connect as a CLIENT to your VPN Provider
4: Setup your phone to connect to YOUR server with the L2TP connection (which works in WinMo and is more secure than PPTP anyway)
5: Your phone will then send all that to your server which will securely pass all data to your VPN provider.
Et voilà, your phone will pass all data through your VPN. Not secure but it works. If you need a more detailed walk-through let me know
You could also try any of the L2TP VPN providers but they're rare and usually more expensive.

What do mean by "a spare server"? how can i do that?
thanks

Hi jagnet,
thanks for your solutions.
the first one seems to be "unsecure" as datas are not encrypted between the phone and the spare server (and be sniffed).
the second seems good... but though complex.
In fact, I don't know how to create a spare server at home, I don't know the material that can and should be use... and yes I'm a noob and I need help;-)
arghh, why its not as easy as for a windows netbook... or for an Iphone

Hello all,
I also tried PPTP VPN connections via my HTC HD2 with WM 6.5.
The connection works fine:
- I can see on the W2K3 server, in the event log, that a new VPN client connected well (and I can also see the IP that has been attributed to the client)
- I can see in the active connection lists on the HTC HD2 the VPN connected
BUT, as soon as I try to transfer data, using VNC or Opera (for example), the VPN connection is closed!
What's wrong with this VPN implementation in WM6.5?
I'm really frustrated... Do you think it's linked to the unsupported PPTP MPPE?
Thanks for your advice.

Hello Mrhankry,
I am looking for a PPTP VPN connection at HD2.
I try here:
Settings / Connections / Connections / Manage existing connections
It doesnt have VPN Tab on this wm6.5....
It did have on wm6.1....
Can you explain where do you do this connection???
ROM version: 1.66.405.2
OS version: 5.2.21869
Manila version: 2.5.19211619.0
thanks,
Joao Claudio

It's so strange that I can use VPN over wifi, but it does not work over UMTS. Anyone has it work?

Normally unless you have a Business account from TMO you cannot use VPN , because you are NAT'd and behind their proxy server, now it seems in some places it will work, due to different configs at that data endpoint, but, for reliable VPN on TMO you need their Business internet/VPN package ..

Hi watcher64,
I dont think it's a carrier problem, because when I use my PC with dial-up connection on my phone, the VPN client on my PC works.
I have tried some provider and got the same problem.

VPN problem on Nexus One

Hi, All
I have a VPN problem that is strange. Here goes:
I have my Nexus One two days ago. It's not rooted and no APK installed on it.
At that time, the VPN worked very well.
Then, I unlocked and rooted it. Then I flashed a Pandora Firmaware. The firmware is here.
://d.epis.me/Pandora%20N%201.1%20for%20nexus.zip
After that, the VPN didn't work. I must wait for a long time after I started to connect, and an error message came out like this: "Can not connect to the server". If I use a wrong password, the VPN will tell me the pssword is wrong. The same VPN server can be connected by same username and password on my laptop, but not Nexus One. It is very strange.
Then I restored the original shipping firmware. It didn't work too. The reply of the VPN is the same as above.
The server is uk.focusvpn.com, and VPN type is PTPP. Encryption type I selected encryped and not encrypted, it didn't work on both.
Now the VPN on my Nexus One is totally broken. Can any good guy help me?

Mods are likely going to move this to a different forum.
If any of the devs want to look at this I'm seeing this also. The VPN Connections app for me to a Cisco Concentrator works fine.
I can't for the life of me get PPTP to work; this may just be a buggy PPTP client in the Nexus One 2.1 build. It works FLAWLESSLY on my G1 with the last CM build. I get a generic message that GRE is not functional; but this is BS - on the same link I can tether my Mac and it works or use the same WiFi On a Windows system or mac and it works. I'm suspecting Google regressed or introduced a bug on 2.1 with PPTP
Cyanogen; or any of the other dev's if you want to "borrow" my PPTP VPN account to debug I'm game to email you the info; PM me. I was going to try this on the emulator and but some debug messages in to see what the specific issue may be...

Yeah. PM me and ill try to fix it for the CM N1 release tomorrow!

is the CyanogenMod also for nexus one?

VPN on nexus (android 2.1)
I noticed on this webpage
code.google.com/p/android/issues/detail?id=4111
that android 2.1 only support old fashion Authentication Protocols
+ CHAP allowed
+ MSCHAPv1 allowed
But
- PAP disabled
- MSCHAPv2 disabled
- EAP Proxy disabled
i searched around and found no program can hack this to enable the later 3
is it easy to enable the above? anyone here can help to configure it or it actually needs a new development?

WM 6.5.3 and Native VPN......

Hi I recently signed up for a StrongVPN 3 Country deal to give me a stable VPN connection in China. I have set up all ok om my home PC and it works fine allowing access to sites otherwise blocked here.
Then i set up a VPN connection on my HTC Touch Diamond2 I can get the VPN to connect using either IPSec/L2TP or PPTP methods, however neither Tunnel seems to allow Internet access to either MS Explorer or Opera Mobile 10 or any other internet program.
In fact when i have established the VPN connection and then start my internet explorer or any other program which needs to access the internet then the VPN connection is dropped.
If I connect the VPN tunnel on the TD2 i can site there watching it for ages so it does not seem to be dropped after any specific time frame, only when I start an internet access program. for instance if i open my Hotmail account then the VPN connection stays until the point when i tap send and receive then it drops immediately and the hotmail account then synchronise mail via the standard wifi connection.
I also set-up my home PC to allow incoming connection and then set up another VPN connection on my TD2 to allow it to connect to my home PC. but whilst i can connect to my home PC i can not surf the internet using the VPN tunnel......I had thought that i might be able to start the StrongVPN connection on my homePC and then access it via the VPN connection from my TD2 to my HomePC but it does not seem to work that way.
My objective is to use my mobile phone to be able to surf social networking sites that are otherwise blocked by censorship.
Sorry for the long post but please could anyone with advise or experience at setting these two functions up on WM 6.5.3 please advise.

Well I think I may have found out the reason for the VPN connection to drop out....I needed to change my setting in CONNECTIONS and where before i selected my GPRS or EDGE service provider i now need to change that to "My Work Network" as this is where i set up the StrongVPN connection. now i have done this change to the settings the VPN connection does not drop out when any Internet program is started.
But I still can not access the blocked websites using StrongVPN on my WM device so I do not really know if it is using the VPN connection or not.....

im also in china and got one vpn for the same reasons as u and having exactly the same problem as u..
plz tell me if u found any solution...

StrongVPN Help desk advised me to input their DNS server settings in to the VPN account settings. I will try this when i get back to China in September. the DNS settings are found by edit the VPN account then next, next and select "Advanced" then scroll to "Servers" there you can select manaual server address and use the one that you VPN service provider recommend.
Let me know how you get on.

I have a similar problem here. I have setup the VPN in network connections but am still unable to surf blocked sites. The VPN worked fine on my PC. I have also changed the DNS setting for the VPN but no luck. But since there was no popup windows telling me whether it is connected or disconnected, how do I know the status of the VPN connection? Thanks!

to see if you are connected just tap on the top info bar then u should see your wifi connect and also your VPN connection. if you enable sound notification for connections in sounds then you will also get an audible connect and dissconnect to let u know. remember to set all your connection settings to "work connections" as i fount if not then when u open opera or other program that needs internet connection it will disconnect the VPN connection.

Thanks. I have tried that and the VPN was online. But opera was just couldn't open any page. Eighter the factbook tab in TouchFlo3D couldn't login. Any idea?

Have the same problem connecting to my home network - Remote Desktop works fine, until I open a browser on my HD2 - changing settings mentioned above didn't help...

Ok - it seems like I've managed to discontinue the connection drops to VPN.
Added wildcards to exceptions http://*.* and https://*.*
This way everything that tries to connect to internet connects via VPN. To stop that - in Work network setting select the same connection you use to connect to internet (Connections > Advanced > Select network)

I'm not sure what you mean by "added wild cards to exceptions"....what exceptions and where on your PDA did you add them?
As far as I was aware you are only able to set up a VPN connection in the "My Work Network" connections area. then to stop your VPN connection from being dropped by any application that access the Internet, you simply change your options to BOTH use "My Work Network" then the VPN connection is used for all applications.
However that said, I still cant access blocked sites using my VPN connection with StrongVPN in China. even after setting my Server DNS to that of StrongVPN it still does not work.
Anyone got any ideas why or how to access blocked content in China on their PDA??????
