PPTP on WM5

Can anyone connect to VPN (PPTP) using WM5 via wireless or GPRS?? When i use my old XDAIIi or II, i can connect by now using WM5 i cannot.
Hope those can connect please share. tks.

I can connect to a Windows 2000 PPTP VPN via wireless -- make sure that in Settings/Network Cards/Network Adapters, your network card is set to connect to the Work network.
Also, in Settings/Connections/Advanced/Select Networks, make sure that the lower droplist (private network) is configured to use the Work network.
Aside from those two items, I can't think of any other gotchas.

Ya still doesn't work......

do you know what the vpn device is that you are trying to connect to?
windows servers tend to be quite reliable. there are known issues with some checkpoint and cisco devices.

Hello,
I am having the same problem! I cant connect via VPN (PPTP) to my Windows Server 2003 RAS setup. It works perfectly fine on my laptop over the internet but when I try to connect using my Cinguar 8125 I get a generic "Invalid username/password' kind of error message. I have tried several differnt things, but I was wondering if there are security settings that are turned off or something like that? I actually have my RAS policy to let any device establish a VPN connection (obviously as long as it is authenticated) so I dont know what to do next... any suggestions??

For me works fine. I have only 2 connections:
a) my isp, with gprs configuration for vodafone
b) my work network, with the vpn connection definition (ip address, user, passw and domain)

I have it set up the same way and I still get the password issue... what kind of policies do you have in RAS?

did you uncheck the security in the connection with the server?
take care with the name user, times exchange get crazy: server/user or only user name for the user field...

Hi! I am not an Network expert at all, but here in Norway with one teleoperator we have to use a special access point name on My Work Network connection to get a public IP-address so Network accepts the connection. Perhaps nothing to do with your problem, but also we experience a lot of PDA users having no problem with pre-WM5 devices and much problems with WM5 devices and VPN

Success with L2TP/IPSec VPNs?

Has anyone had any success with L2TP/IPSec VPNs and Windows Mobile 5 or 6? I have no problems with getting PPTP to work but have NEVER had any success with L2TP/IPSec. I have valid Client & Server Certificates but I have never been able to get a connection; in fact the HTC Wizard I have never even attempts to make a connection (I have a sniffer on the Ethernet port my Wireless AP is connected to). I have tried using Certificates & Pre-Shared Keys but the results are the same - The Wizard never attempts to connect, with PPTP it works every time.
The Server I am using is a Windows 2003 RRAS server and I have verified with a Windows XP Client that L2TP/IPSec works.
I have asked the question before but have not had any helpful replies. I would be grateful if anyone who has set this up successfully can let me know and maybe give me a run-down of the steps you used. I am not interested in any 3rd party VPN clients, it must be the built-in one.
Thanks
Andy

Hi
Yes I have had the same issue with both the wizard and now hermes tried wm5 and wm6. I think it maybe related to NAT-T translation as am unsure from my reading weather MS supports NAT-T on the mobile end. If data session is being NATed by your provider then this may be the cause. Probably need to check the ip packets comming from the phone to see what it is sending out. Is that what you did or is the sniffer at the other end.

It has nothing to do with NAT traversal. WM5 (and WM6 probably?) does NOT support NAT-T, however I am not attempting to get this working over NAT. As I said I have a put a sniffer on the Ethernet port my Wireless AP is connected to and my Wizard does not transmit anything when configured for L2TP/IPSec (except a DNS lookup for the VPN server name if I enter it's DNS name as opposed to it's IP address). With PPTP it works and I can happily see the packets it transmits on the sniffer.
This is really frustrating as it looks like no one has ever got this to work
I had a HP iPAQ 6365 previously with Windows Mobile 2003 and I managed to get it working on this quite easily

I now have this working on both the wizard and the hermes.
I am a bit confused with your last response as ipsec port 4500 is nat-t and is required and is being transmitted by both the wizard and hermes in my case.
My setup maybe somewhat different to yours as I have a windows sbs2003 server running isa and rras. It is sitting behind an adsl modem router connected to the internet. The data connection on my phone is edge network on the wizard and HSDPA on the Hermes. Also have tried this via WiFi as well.
Steps I used
On server side router
On adsl modem router setup forwarding udp ports 500 ipsec, 4500 nat-t and 1701 l2tp and protocol 50 IPsec ESP. I selected l2tp/ipsec from its predefined list but noticed it missed udp 1701 so added this manually.
On Server.
ISA management selected Network Configuration right click and selected Allow vpn connections. This essentially setups the ip filters to allow incomming protocols and then sets up rras for pptp and l2tp ports.
In rras configure a preshared key by right click server/properties/security tick allow custome ipsec policy... and added preshared key.
On mobile
settings/connections
My Work Network
Edit my vpn servers and added new IPsec/L2TP connection.
Works a treat hope this helps
I did notice on another forum something about disabling the phone skin but I did not have to do this.

What ROM are you running on the Wizard? I am currently running a WM6 ROM but I previously used the official QTEK update (AKU 2.3 I think?) and then various WM5 AKU 3.3 ROMs. I have tested this with all of them and none have worked. If I could just see it attempt to connect I would be happy The fact is it doesn't transmit anything at all and all I see is the dialogue box on the Wizard saying 'Cannot Connect'....
With regards to NAT-T I read that the VPN Client in Windows Mobile 5 was not capable of this, I could be wrong however?
Andy

Sorry didn't have signature updated I'm running WM6 MBE on the wizard and WM6 Black on the Hermes
Ok I am still confused can you tell me exactly how you are connecting to your work network. Wifi or gprs.
Can you check also.
Under settings/connections/advanced/select networks make sure you have a separate ie different connections for the internet and private network. The Intenet settings will be your service provider grps settings.
For the private network mine is set as My Work Network. Edit this and make sure sure you do not have any modem connection listed ie we want to make sure it goes out over our existing connection and does not try to make a new connection. Make sure the vpn tab has your vpn settings as required they must be listed here and not under the Internet connection.
If you are using WiFi you must make sure the network setup is Connects to: The Internet and not set to Work. If it is work the VPN will not connect. You can not change this on the fly need to disconnect and setup again.
PM Me When you get to work given time diff I should be home. Might be able to test connection to my server at home then can check logs etc
Also use Task manger v2.7 to view netsats on phone to confirm udp ports and ip routes etc. It will show you if the phone is indeed sending should see upd ports 500 4500 and 1701 being used.

I am using WiFi, this is all in a test environment so I have full control over everything. Under Connections I have 'My ISP' and 'My Work Network' listed. 'My ISP' has a modem entry, 'My Work Network' has no modem but has a VPN listed with the IP Address of the VPN server and set to L2TP/IPSec using a certificate on the device (I have tried with pre-shared key also). The WiFi entry is configured as 'Connects to The Internet'.
I enable the WiFi and verify I have connectivity, I then go to Connections, click on My Work Network, 'Manage existing connections' select the VPN tab, hold down the stylus on the entry and click connect and I almost immediately get the dialogue box saying 'cannot connect'. If I edit the VPN entry so it is PPTP it works every time. As I said I have a sniffer on so I can see what the Wizard transmits and it when set to L2TP/IPSec it doesnt transmit anything whatsoever, with PPTP I can capture the whole conversation.
Thanks for any help you can give me.
Andy

Ok I have now also tried using certificates and your right it does not seem to sending any info at all. It might ahve something to do with checking the certificate store first I ahve had issues before with Cisco vpn and certificates you have to get the nameing and certification justs right before it even starts the connection.
So first thing lets try pre shared keys as I have got that working. I will PM you my server details if you wish to try that first.

I have just re-tested this and using a pre-shared key - same result
There is a brief flash of 'connecting' when you click connect but then the 'Cannot Connect' dialogue box appears, nothing gets transmitted. I have tried entering different IP addresses (public, private etc) just to see if it will transmit anything - it doesn't regardless of the IP address I enter.....
Andy

Andy
check your pm
Are you sure the wireless ap is actually passing the ipsec/l2tp traffic.

Working, well sort of.....
After a lot of messing around I now have this working, at least partially........
Following a soft-reset I can connect to a Wireless network OK (either a new one or one that is pre-configured), I can then connect the VPN using L2TP/IPSec. I can also manually disconnect the VPN and re-connect without any issues. However, when the wireless is disconnected (i.e. turned off from CommManager) and then re-connected the VPN will never work again, unless the Wizard is soft-reset.
Does anyone know what is likely to be causing this? some application in memory or a registry 'state' entry
Does anyone else see this behaviour?
Andy

I had exactly this with L2TP/IPSec on the MDA Vario II, but the same settings work as they should on my Athena.

HI!
How can you DISCONNECT?? Do you get a "Disconnect" button or menu item somewhere??
How do you know you are connected to VPN?
Thank you,
Dmitry.

A bit late but...
I have a possible solution to the fact it doesn't send ANY traffic on a connect attempt - on my XDA mini S (HTC Wizard) it requires me to put something in the 'domain' field on the username/pwd screen before it will start the IPSec negotiation....
Now I just have to get it o complete the process with the sonicwall...

Revisiting this
I can't get PPTP going on my HD2. Thoughts?

bumping this message

I have tried all the usual vpn software (for 3g connectivity) the only third party software that connects is the ncp software, but I get stuck because it wont accept a challenge response grid.
Symantic - won't auth
Green something - doesn't connect
MS VPN - doesn't connect
I have been able to connect in the past with an iPhone, but without a java i can't connect to most motorola hardware devices at work so it's useless. I'm testing a G1 on 1.6 now and it fails to connect also. Going to try openvpn today sometime. MY friend has his Eris working, so I know droid OS works.
I work for a large company and switching vpn hardware is out of the question, so if anyone has a 3g resolution for winmo, I won't have to trade my HD2.

Hi,
L2TR VPN with the Windows Mobile is working !!
The trick with L2TR VPN on WM is to use: a IP address (and NOT a hostname)
Strange, because using a hostname with PPTP VPN on the Windows Mobile it works.
With the trick L2TR works perfectly.
Chris

Hello. This is my first foray into VPN on Win Mo. I can establish a PPTP connection between my Imagio (stock Win Mo 6.5 R1) and my SBS 2008 server. I can ping the server and can browse the company web page. But I am having no luck accessing file shares. I have Schaps Network Plugin installed, but it doesn't see/can't access the shares. Will switching to IpSec VPN work? If so, any guidance on how to set it up on SBS 2008.

Proxy Setup Problem DOPOD D810

I am using DOPOD D810 and Operating System is WM6. I try to connect to Access Point at my company. The Company Administrator said I have to set proxy on my PPC. I set my PPC proxy and after I click OK and go to other page and try to Access outside website such as google, it was fail like can't access outside website. After that I go back to the proxy setting part, the proxy that I have set was gone. I did like this many and many time and it was respond me the same thing.
It did not happen after I flash my ROM to WM6. When I used WM5. It has the same problem. Previous I thought it might be a problem from OS so I up my OS to WM6.
If I connect to ADSL Access Point at home where is no need to set Proxy, my PPC can connect to every website.
Could anyone please help me to solve this problem. I am not sure it is a hardware problem or not. If so, I will claim my PPC since it is still on varanty.

Proxy Problems in WiFi
I am using an HTC P3600 and I have used 3 different versions of ROM (both WM5 and WM6) and I have exactly the same problem. Unfortunately, I also have to use a proxy at home on my WiFi to access the Internet. It appears to me the the auto-configuration removes the proxy when you try to communicate using WiFi. When I turn off my WiFi, the correct proxy is back in the configuration again, but not there when the WiFi is turned on. I have been looking for ways to turn off the auto configuration of the proxy but I have not found one yet. I believe it should be able to be done by editing the Registry. I have a friend with the HTC TyTN and his device does not have this problem.

Randy

ICS & VPN with WM6

My searches on the web haven't yielded much help or information so I thought I would come to the experts...
I have a Treo 750 that I just "upgraded" to WM6 2 days ago. I noticed that DUN has gone away and was replaced by ICS. After configuring my laptop to use that instead of DUN I connected and was surfing the web. My problem now is VPN. I travel frequently (luckily I'm in the office until Jan.) and regularly used my phone to connect to the corporate network via VPN. I also work with a lot of other companies and have VPN access to their systems as well. Basically now I can open my Cisco VPN client, connect to a VPN gateway, authenticate, get assigned all the appropriate IP information, but cannot communicate on the network. What gives? Is there a solution to this? If not, what the heck was MS thinking when they did this!? My phone is basically useless for one of the major reasons I bought it...
Any help is appreciated!
thanks!

Ok, further searches found that DUN can be added back into WM6 via a cab that was posted here at the XDA forums. I installed it and the DUN service is now visible again. I unpaired by phone and laptop, re-paired, and included DUN. Now when I try to connect, I get the DUN connection box after the bluetooth connection is initiated but when I click DIAL I get the DIALING... prompt, followed by Error 678: The remote computer did not respond.
Anybody get this working on a Treo 750? Thoughts, ideas suggestions?

What is the ip address you are getting via the cisco vpn client
It maybe that it is in the same subnet as the ip address assigned to the pc from the wm6 ics. The ICS gives the address 192.168.0.1. and if your Cisco is also giving a 192.168 address then you will have two routes for the 192 address range thus giving you the problem when accessing hosts.
If this is the problem Im pretty sure you can change the address allocated via the ICS using a registry editor. If not you may be able to get work to use a different range for you on the cisco vpn.

Our corporate network is 172.x.x.x so it's nowhere near the 192.168.0.x assigned by the phone. When I look at the route in the VPN client I see 192.0.0.0, 10.0.0.0, and 172.0.0.0 so I am assuming 192 is my laptop, 10 is the phone, and 172 is the corporate network.
I'm guessing NATing is the problem. I've been reading that if I use a different APN (isp.cingular instead of wap.cingular) there is no NATing. I've tried both, and I've tried turning off and on the "force AT&T" proxy setting to no avail.
Tried the DUN cab hack that is floating around for WM6 also. The service is active again and I can also add Modem Link back in and my laptop sees my Treo as a modem but when I dial I get an error stating the remote computer did not respond. I'm guessing along with going from WM5 to WM6 AT&T also updated the radio so the old communications protocols don't work anymore?

Hello Sir,
I have exactly the same problem... I have successfully connected via VPN, however unable to communicate with any devices on that network... Then what is the use of VPN on the phone? I've tried searching online for answers, but no luck... People are having the same problem but no one knows how to solve it... I'll try and trouble shoot this problem more as soon as my exams are done...

Hi
Working successfully for me. I am using Imate jasjam wm6. Pc using cisco client connecting via ics on phone. I have telstra 3g connection tested ok on both telstra.internet (Nated ip) and telstra.extranet (real ip).
You are correct it may be an nat issue. Can you check that your transparent tunnelling is on as follows: right click on your connection entry in cisco client and select modify then transport tab. Check that enable transport tunneling is enabled ipsec over udp(Nat/pat).
The other thing to check is that the cisco vpn server aslo has transport over Nat on as well.
Also are you sure your corporate ip range is 172 or is that the range given by the cisco vpn to clients.

Transport tunneling is on (always was). I'll have to check with our network admin and check on the VPN server setting...I guess as long as I have connectivity back to the office, I don't need it that badly for all the customers I need to connect to at various times.
Yep, positive on the corporate IP. Right now it is 172.28.1.87 and I'm in the office.
Thanks for the help so far. Got any other suggestions on how I can troubleshoot further?

One other thought...should I modify the registry on the phone to assign a different IP address to my laptop? Would that help?

Same Problem
MX. I am having the exact same issue but with Securemote VPN. I've looked through the registry and found the assigned address, but I'm wary of changing anything until I can find some more information.
Anyone out there ever change the DHCP configuration for their phone?

Somewhat related question?
Im attempting to route my connection on my mobile through a laptop acting as a wan bridge, then uplinking it into the router. The issue Im having is that XP and WM6 both use the same IP Block. Ive read and read and cant find much to tell me how to change the WM6 IP BLock to something like 192.168.2.1 rather than the default 192.168.0.1
Does anyone have any pointers? Ive looked through the registry. There MUST be a simple way to change a default.
To clarify my setup, I am using ICS Via USB into a UMPC laptop running XP. The UMPC is set to share that same connection back out over Ethernet. The ethernet runs into my WAN Uplink on the router and then back out via wifi/rj-45
This setup works as I have done it using Wifi with other networks, and I can chose the "Lan3" to share under the advanced settings on the UMPC. The reason I dont just share out via Wifi from the start is that Wifi on my Kaiser and Raphael both make the device to hot to charge, thusly killing the battery within a couple hrs of sharing. If I share via USB , it stays pretty cool and still charges.
Anyone have any pointers?
I have already tried tricking XP into using the Lan on another block but as soon as you try to share the USB lan, it reverts back to the 192.168.0.1
The only way I can imagine is a registry modification or a program change in ICS.
Thanks Much!

WM6 won't connect to PPTP VPN over gprs or wifi

Hi,
I am trying unsuccessfully to connect to a PPTP VPN using the VPN client built into my new HTC TyTN II.
Wifi - I can connect using a WinXP SP2 laptop using wifi through my home linksys wireless router (which has PPTP passthrough enabled) using the standard Win XP vpn client. When I try with my TyTN II, I can browse ok but if I set up a VPN connection I get "VPN server problems. Verify your username and password, etc"
GPRS - If I try to connect over GPRS, I connect to Orange GPRS but when it tries to connect to the IP address of my VPN server, I get the same VPN server problem error message. (As a side issue, I asked Orange to enable my account for vpn which they did, sent a SIM update and told me to change my apn to 'internetvpn' instead of 'orangeinternet')
As I can connect through my wifi connected laptop, it seems to point to my WM6 vpn client but my forum searches suggest that the WM6 client works ok. Oh, and yes, I have checked that I am using the correct vpn username and password!
Any thoughts greatly appreciated - the ability to maintain some linux servers was my main reason for getting this phone!

Bump!!! Same problem here. I have all the proper ports open on my router and still no luck.

I've been trying to resolve this with the people that manage my vpn server which is my case is a Watchguard firewall - apparantly Watchguard isn't compatable with PPTP on WM6 and they have suggested using IPSec and have provided me with a client (not that I've got that working yet either!)
I suggest you contact the vendor of your vpn server and ask them whether they are compatable and how a WM6 client should be configured. Post anything you find out here for the benefit of others.

WM6 don't connect to VPN over GPRS/ WiFi
Friends...
I have the same problem... the VPN server is Windows Server 2003... My PDA has WM6 (with in-build VPN client)... then VPN PPTP would work OK... but What is the wrong??
Regards...

I also could not connect on vpn over GPRS and got error message, but after I tested all installed programs I have found out that my SPB GPRS Monitor was the reason for the errors. So I killed it.
Now VPN over GPRS connects and looking into register I see that I am really connected i.e. I got DNS server IP, I got name of the local network and dynamic IP for my HTC, but nothing works. As I have found out from server guys they see me but my dynamic IP is not logged in server DNS, so no program sees me and I can not work.
Can somebody help?

Same
I have a similar problem but the difference is that i don't even receive an error message. When i click connect NOTHING happens!! The wifi i am using is an open network but I must connect to vpn to connect to the internet.
Please help as i really need to get this working...

I have been trying to iron this out with IT at my office as well. I have been trying to get WM6.1 VPN working for nearly a year.
I have a TyTnII and my IT office just bought some kind of WM6.1 Motorola/Sprint Smartphone as well which they actually asked me about setting up for them.
The problem what I am experiencing is that I CAN connect to the VPN server (I use one of the TaskMan progs that has ipconfig built it, and I am getting an appropriate IP from the VPN server). BUT I can't browse ANY intranet sites via PIE or Opera Mobile 9.5. Whenever I try to browse to an intranet site I just get nothing, browser does nothing for ~10min then gives timeout error.
I have heard that this has to do with an inbuilt error in the PPTP module of the VPN client that incorrectly makes VPN server requests using the IP address assigned by the GPRS/EDGE/3G/etc. connection rather than the IP address assigned by the VPN connection, obviously will cause problems!
Anyway, we are investigating 3rd part VPN clients...

Only IPSEC works
I also made many tries to get vpn working over BT PAN profile.
The only configuration which worked for my was IPSEC with the Safenet SoftRemote-LT Client on PC.
With the windows native pptp based vpn does not work .
I got the error code 721 what means that the GRE protocol (frame type 47 on port 1721) does not pass through. This seems to be the the real problem of the packet filtering components of the WM device. The problem is not related to bluetooth or PAN Driver, because it behaves in the same way if you try to do it over USB port. No way.

You guys might want to check out my post about getting my PPTP VPN working and actually syncing ActiveSync on a fixed schedule regularly over VPN.

Getting what you want to work over VPN requires work URL Exceptions so that the traffice is properly routed.

Watchguard does support PPTP, your IT guys just need to configure it. As for IPSec which would be awesome because there is an app call Greenbow that will connect you over 3G doesn't work with Watchguard. You can only connect using their own client for it which needs a license and isn't support on Windows Mobile. They got a hate email from me for that crap.
