I have been trying to establish a VPN connection with my xda over gprs to my office computer (PPTP) but I am not sure I have made the appropriate settings. There is no place to type in my username and password (except for the gprs connection).
Can anyone guide me on how to ensure a proper connection?
Also, I am not sure what the VPN connection will mean in terms of pocket pc functionality. Will it mean that I can access my office e-mail which would otherwise require a direct dial in? Will I be able to synchronize with my office outlook?
I would greatly appreciate your help. Thanks, apap

hi,
suggest ringing 0845 6006886 (O2 GPRS Helpline).
They have a PDF Doc that may help. They will e-mail it to you.
Doc Title VPN_Access_over_mobile_web.
Good luck
Ric.
Thanks for your help Ric.
I have followed the settings as discussed in the pdf file but I have not had any success. I will call the helpline.
private networks
Please note that if you are using O2 and your office have a private network range in the 10.0.0.0 range, you will have problems due to the subnet mask used, and the fact that O2 use NAT.
I have written a utility which monitors the routing table, and overcomes this problem by narrowing the net mask. Anyone who is interested, contact me for this software: [email protected]
I tried to 'give' this software to O2, but they didn't seem to care. They didn't really seem to understand the problem.

How about this: we'll dedicate a page to it on this site, and possibly even include a small tutorial that deals with networking stuff in general. If everyone in the know contributes a bit of their knowledge, I'll lay it all out, add the screenshots and put it on a page.
Re: private networks
Thanks.
Here's the gist of it.
Often, corporate networks use addresses in the range 10.0.0.0 - 10.255.255.255 in order to create private networks. This address range is designated for this purpose, and is the only class A range designated as such.
O2's GPRS network uses NAT in order to cut down the number of IP addresses they require. In doing so, they also use the private address range.
It is not recommended practice to use NAT for subscription networks, as they do not provide a 'complete' internet service. Certain peer-to-peer services will not work through NAT, as they require both devices to be publicly addressable - this however, is not the cause of this issue.
Lets look at the process of connecting to a VPN.
1) a 'dial up' connection is made to the GPRS service. When I say 'dial up' I do not mean a circut switched call is made (before you techies correct me), but still, some kind of PPP connection is made.
2) IP addresses are negotiated. An address is allocated to the device in the 10.0.0.0 range. During this allocation proceedure no subnet mask is specified, and the device assumes 255.0.0.0 as for a class A network.
3) The device adds a route to 10.0.0.0 mask 255.0.0.0 on the GPRS virtual adapter.
The connection to the VPN can now be made
1) a 'dial up' connection is made to the VPN service.
2) IP addresses are negotiated. An address is allocated to the device in the 10.0.0.0 range (depending on corporate config). During this allocation proceedure no subnet mask is specified, and the device assumes 255.0.0.0 as for a class A network.
3) The device adds a route to 10.0.0.0 mask 255.0.0.0 on the VPNvirtual adapter.
All seems fine - no? Try connecting to any host on the private network. Mail server, terminal server, web server. I bet you it doesn't work. That's because two routes have been allocated on the 10.0.0.0 mask 255.0.0.0 network. When you try and connect to your mail server (eg 10.0.0.6) the packets go straight out through the first matching route - the GPRS, and never even see the VPN route.
My software tool watches the route table (I use a function in the IPhlpapi.dll for those interested), and waits for a change. When it spots a change, it re-writes the routing table, narrowing the routing entries to 24 bit masks (it works out the missing octets from the gateway address).
So an example would be:
10.0.0.0 mask 255.0.0.0 gw 10.34.23.254 if GPRS
10.0.0.0 mask 255.0.0.0 gw 10.0.0.1 if VPN
becomes
10.34.23.0 mask 255.255.255.0 gw 10.34.23.254 if GPRS
10.0.0.0 mask 255.255.255.0 gw 10.0.0.1 if VPN
This allows you to access stuff in the 10.0.0.0 network.
Drawback:
You won't be able to peer to peer with other O2 XDA's who aren't on the same class C netowork - big deal, does anyone do this?
You are limited to contacting hosts on the same class C within your private network. I am working on broadening this range.
Files:
There is 1 file required - the executable, which should be placed in the startup folder. Let me know where to send this, and it can be made public.
util.
To keep you updated. I've just updated this slightly. It no longer requires MFC. It is 1 x 5.5 K executable.

Martin
Please note, not everyone will need this update. Only if your office uses a 10.0.0.0 subnet.
Thanks for all the enquiries.
Can I share the files - VPN_Access_over_mobile_web.pdf?
Hi ,
Can I share the files - VPN_Access_over_mobile_web.pdf? I am also testing the VPN conection over XDA GRPS, but if it is possible , pls mail me that PDF files. [email protected]
Thx

Don't have this file to hand, but if it is the one I think (provided by o2 UK) it is on their site somewhere.
VPN to Win2k server (with fixed ip, and internal ip of 192.168.blah-de-blah) worked first time following those instructions, as did Terminal Server used to remotely control it.

What VPN does for me.
Me and my significant other have 3 servers in our closet and host exchange (email), Active Directory, and outlook mobile access as well as things like ftp, web, and most importantly VPN. All my email that comes to us goes into my Outlook box on the exchange server then activesync sends a text message to my tmo pda phone and activesync begins downloading my mail and synchronizes my contacts and calendar. Once that is complete, a VPN connection is started up and the pda syncs with my desktop computer, so programs like vindigo and files like my documents are up to date. I even have the option of installing over the air or browsing my files on my computer at home.
Hey Sytris, I'm setup the same way pretty much but I've tried with 2 different devices and I can't get it to sync with the local computer. The active synce with exchange works fine and the vpn connects just fine. The active Sync app on the server then gets the connection from the PPC but shows connected as guest instead of my device and the active sync on the PPC still shows connecting but never goes anywhere. Did you run into that when setting yours up? Any suggestions? Thanks - Jim
About PPTP connection via PC I found nice tutorial step by step here at supervpn.net/blog
About mobile, you should try to contact some VPN provider, they have nice live chat support so they can answer you probably on all your questions.
For setup your vpn on your phone you can find solution on worldvpn.net
Hi all,
I have an imode subs. which originaly is only to be used on reserved mobile phones from the operator. I could have the parameters to connect from all phones. It is working nice on my Xda2.
But the proxy they use only allows me surfing (port 80).
Therefore I would like to know how I can bypass the proxy (10.10.100.10:5080) with my own home server translating/forwarding the request from my XDA.
Example :
I connect GPRS with my XDA, I tell my Pocketoutlook to use pop server "myhomePC.com:80" and my home PC will transfer to "MyPOPsupplier:110"
Same could apply for other services...
Thanks For your help :?: :?: :?:
not possible, it is a http proxy so it restricts which connections you make to port 80. Out of my experience with imode i know going to the proxy for POP3 does not work. The only thing which is easy and I also use for my email is http://mail2web.com. There you can check POP3/IMAP (+SSL) to read your email on your xda 2
hope this helps
Ever tried this one ?
hi thanks for your reply. Have you ever tried this one ?
http://www.pocketgear.com/software_detail.asp?id=9539
Can some users of Imode on XDA try it and let us know the results ?
I can have it working... do not know why because it is only http requests.
Thanks
Stéphane
That is because it tunnels your mail over HTTP. This is only possible with MSN or hotmail accounts and not with other POP3/IMAP accounts.
I recently purchased a tmobile mda and was trying to access my campus's network. But when I logged on, the only page I could view was about downloading a vpn client for multiple os's (but no windows mobile) to use the network.
Is there a vpn client for windows mobile?
Any help would be great.
Thanks!
There's a built-in client that will handle L2TP and PPTP VPNs. If you go into Settings/Connections and click "Edit my VPN servers" you can configure the client for your VPN. It's worth a try.
Tried that, didn't work... I decided to ask my University about their network, they said it was a cisco 3000 or something... And also informed me that "to their knowledge" the windows mobile 5 built in client isn't compatible...
I then went to the College of computer science help desk to see if some peers could help me. They said someone had bought a $100 program to be able to connect to the concentrator but didn't know who made it or where to get it.
Does anyone know of such a thing? Or a cheaper alternative?
AnthaVPN
I have found AnthaVPN wich is about from 40$ to 100$ depending what you need.
I'm trying also to open VPN without this IMHO too expensive solution. But if it's the only way - then I need to buy....
Maybe some kind of tunneling from own Linux-server (With Swan) might be the free solution....
I have been testing Bluefire Security's VPN and it works great, but my employer is using a Nortel system sio I cannot comment on the Cisco compatibility. It costs $79. I have also tries Antha but is cause problems enabling Wifi and Gprs.
John
Long time I could’t make connection with the built-in VPN client. After the latest ROM update from Qtek it works (I tested only PPTP). I can make VPN to SBS server and Windows XP. Also I can use Terminal Services true VPN connection.
The only thing I can’t get working is to access network shares (I tried GSFinder+ and NetUse).

Hi,
I'm currently on a HTC Trinity using Mary's 3.3.5 ROM and want to be able to connect to my universities WiFi network but to do so I need to use a VPN tunnel, anyone recommend a good PPC App that will allow me to connect to my universities VPN?
Cheers,
Mike

WM6 Pro includes both a PPTP & a L2TP/IPSec VPN client. This will work with most VPN routers & firewalls, however they may not be configured to support it. If you can connect using Windows 2000/XP's built-in PPTP or L2TP/IPSec VPN Client then you can almost certainly connect with WM6's.
A lot if VPN Routers & Firewalls are supplied with a 'free' Windows client that has the documentation geared around it. However most (if not all?) of these products will work with the native VPN client in Windows 2000+ (and WM5/6). I would try and stick with the L2TP/IPSec client but this requires some additional steps over setting up PPTP - on both the client & server (router). It is worth the extra steps in my opinion though.

I have the same problem ... I am not able to connect using the default VPN client ...
Hi,
There's a great review of vpn clients by Menneisyys in the Wiki. It's entitled:
'Access Your Desktop PC From Your Pocket PC!'
I'm sure you'll find it very useful because it would point you in the right direction as regards VPN tunnelling to your Uni's server.

HI!
Thank you for your reply, but this articles are about "Remote desktop" - like solutions for WM - based devises. Not for connecting to VPN.
Did anybody have had any success so far?
Any working 3-rd party VPN clients / Solutions?
Thank you in advance.
Dmitry.

Hi,
You might find Manneisyys' review very long but if you take your time to read it, you'll see that he talks about the various VPN clients and how they compare. VNC, VNC+, etc are all mentioned there.
Just take your time to read it.
kiwi992.
Nice article, is the VPN working?
Do you have the WM6 VPN client working? Specifically the ActiveSync -> VPN -> MS Exchange functionality that was there under WM5?

Thank you for your answer!
But. Once again: the article talks about REMOTE CONTROL with the use of things like: RAdmin, MS RDP, etc.
This sofware - are remote desktops, so called VNC, not VPN clients in a classic way.
There is a little mess we get at the moment. (I've defenetelly got)
Let me describe in detail:
People need VPN here for many reasons, for me it is:
- to connect to some VPN through WIFI with our WM5 \ 6 device.
In my case- this is a public WIFI internet provider, which has a wifi coverage in the city.
Wifi is open PPTP. I need to type in a login \ pass on the web page I get, to start using the internet in current wifi session.
The ALTERNATIVE way to conect to internet - is to establish a VPN connection over the wifi.
I can successfully do in on the laptop.
With my UNI, WM5, AKU 3.5 - I can connect to VPN with the built-in VPN Client, but the first request to internet (via browser or Messaging send-receive) - drops my VPN connection, as it described here in the forum.
So: we need some software that can work.
I tried so far:
1. BlueFire VPN - just can't connect.
2. Antha VPN - just doesn't work.
I have heard thah on some other ROMs there is no problem with the built-in VPN client for PPTP, will try with some other WM6 ROMs later.
Any solution so far?
Thank you, kiwi992
Thanks to everybody!
Hi, im sorry for my bad english.
I have the same Problem. I search for an VPN tool. I have wm6. I know ther ist an VPN client but it doesn't work. To connect to the VPN in my University I need the L2TP/IPSec "safety andcertificate" but I don't kwon where I can load this.
thank's for helping

Hi! The L2TP/IPSec is a special story.
It is widely discussed here at forum: xda-developers > General discussion > Networking >
Search for *VPN* string on this forum.
This is the: http://forum.xda-developers.com/showthread.php?t=302520&page=2&highlight=*VPN* one of the success stories.
You need to obtain the certificate from the system administrators of your network. You may also have some "magic" URL in your campus network, where you can download the required certificate. This URL should point to the inranet web page of the web interface of the VPN server.
If your goal is to securely connect to some specific computer on the network, you should use one of the VNC programs: the VNC server part on the computer, and the VNC client on your device.
In any case - first check your certificate \ settings on, say, Windows XP laptop, connected through WIFI, first, then continue with the device.
Good luck!
Dmitry
VPN problems
I don't know if this issue is specific to my device (pharos gps 600 gps phone), or to windows mobile 6 which I'm running.
I can't connect to my vpn through wifi, the reason being is that I cannot associate any connections through the wifi card with the vpn info.
Wifi card doesn't show as a selectable modem in the modem tab next to the vpn tab in the vpn config. Only modems are cellular line modems, bluetooth, and one "hayes compatible com1" which is my usb I would guess.
Does anybody know how I might get around this?
Hi!
I am looking for a VPN Client to access a secured Network (Cisco VPN) with my PDA - Symantec claims it's "Mobile VPN" is able to do such, but i was not able to find a retailer yet that would sell it.
Anyone here who knows a good alternative?
Cheers,
Thomas
if your a registered cisco user then you can possibly get it here...

if not, then i would guess your pretty much out of luck, unless you can find it on a torrent site

Why not use the native vpn client. ipsec/l2tp works using both preshared keys and certificates as long as the cisco vpn concentrator is setup correctly.
