VPN over GPRS problem (Load Pocket IE, disconnect VPN?) - Networking

Problem on VPN over GPRS
1. I made the GPRS connection and successful, It showed “G” at the top bar and the connection is “GPRS Connected” with public IP.
2. Then I enable the VPN connection (PocketGVC), it showed connected and assign the IP successful (10.X.X.X), the connection is “ Work Network Card”
3. I have used the ping tool and ping the intranet IP successful.
4. When I use the pocket explorer to load the intranet page, it will disconnected the GPRS connection, then the VPN client connection status will show “Waiting for LAN IP address”
Anyone can help on this problem?

I also have the very same problem.

What is difference between Internet+Work? And VPN?

I have installed the Sandisk WIFI on my XDAII for internet and network (Resco Explorer). All is connected to my Wi-fi ADSL Modem/Router with a network cable to my PC. It all works fine.
I do have two questions, just to make myself sure:
Settings > Connections.
1. I set the connection as "Internet". What is the meaning of "Work"?
2. Why should I set up a VPN? And what is it? I set up a VPN with info from my ADSL provider.

It aint very well explained in the manual and is not intuative at all. An 'internet' connection is one through wish you can obtain internet access, A 'work' connection is one through which you can access your internal servers, but not obtain internet access. In a 'work' profile, you can make a change in the proxy server settings such that you can, through a 'work' profile obtain internet access.
VPN is 'virtual private network' this is a secure connection to your work/home network that is routed over the internet. Via a VPN, you can for instance browse network shares on your work network, or connect to the company intranet. To use a VPN connection, you need to have a VPN server to connect. A VPN server may be provided by your company or your router may support it. NB: A VPN Passthrough on a router is not a VPN server - it simply means that you can VPN out from a natted machine on your LAN, or, in some cases, place a VPN server within your lan.
My device is setup as follows in connections --> Network Management
Under the first drop down for internet I have a profile 'My ISP' with a single GPRS connection to APN: mobile.o2.co.uk defined
Under the second drop down for work, I have a profile 'VPN Settings' which simply has 2 VPN settings defined 'Work VPN' and 'Home VPN' (all other settings, eg 'modem' are left blank).
When I connect via GPRS to mobile.o2.co.uk, I get 2 VPN options appear the connected GPRS connection (in the 'connectivity' speech bubble that appears when you click the connections icon in the bar @ the top). These are 'Work VPN' and 'Home VPN' with a 'connect vpn' option next to them. I just manually connect these as required.
For WiFi, I make sure that my wifi adapter and wifi network I am connected to is labeled as 'internet' rather than 'work'. I then get the VPN options mentioned above appearing below my wifi connection in the 'connectivity' speech bubble. Unfortunately they refuse to connect!! I dont know why. Looking through the forums, it seems that no one is able to get the VPN to connect over an existing wifi connection.
Hope this helps

I-Mate PDA2k Wi-Fi -- SENAO wireless Access point

Hi guys,
I don’t know you guys can help me or not well My problem is
I’m trying to connect my I-Mate PDA2k to Senao Wireless Assess point my access point connected with my network switch .My access point showing WAN light and on my mobile also showing “W” its mean PDA getting signals but I can’t access internet from my PDA.
I don’t know how to configure access point I took access point without catalog and serial cord I don’t we use serial cord or not.
In simple words I want 2 access internet without GPRS.
Information:
SENAO
2-port switch wireless router printer server
SL-2511SR PLUS(F200)
MAC 005018578BO
I-Mate PDA2k Microsoft
OS windows 2003 CE
Local network
IP Class Local = 192.168.0.XX
Internet Sharing = ON
Look for help on configuring your the Senao web site for configuring your wireless router: www.senao.com.tw. I have an access point and it's working like a charm with my Blue Angel.
If you don't have a DHCP server or you have not configured your wireless router as a DHCP server, follow these procedures on your PDA:
Tap Start, Settings, Connections (tab), Network Cards (icon), Network Adapters (tab), tiacxwln Compatible Wireless Etherne....
Then check: Use specific IP address. You'll need to set values for IP Address, Subnet mask, and Default gateway. You IP address should be (quoting you) something like 192.168.0.xxx and subnet mask is probably 255.255.255.0
Also be sure to tap on Name Servers, and fill in the info there, you'll need a DNS address to access the Internet.
Finally, to configure your proxy server, go back to Connections, Advanced, Select Networks, and create a new connections and configure the proxy server accordingly, if it exists. If you're supposed to connect thru SecureNAT (ie Default gateway), you can simply ignore this step, or create a network profile that "connects you to the Internet" without specifying a proxy server.

Qtek Exec and wireless network

At my home, I have a router wifi and a little net with static IP.
If I try to connect the Qtek to the net by WiFi, it's all ok and the signal is strong, but if I try to open a site by Internet explorer or Opera mini, I have an error: "I can't locate the resource...".
So, I can't navigate in Internet.
Any idea?
are you applying a static ip to the Universal?
does your Router do DHCP?
It sounds like your Univ is picking up the network but not being signed an IP address,
Yes, I have assigned a static IP to my Qtek, I have assigned IP, Gateway and DNS in "tiacxwln compatible wireless ethernet" and it connects to the net very good...
ok, then check the proxy settings in connection manager, i have mine ticked to say internet access, but unticked to actually name the proxy.

Has anyone got a VPN connection to work with a T Mobile MDA?

I am trying to establish a VPN connection but cannot get the connection to work.
I am using the built in MS VPN client of Win Mobile v5.0 (5.1.1700 build 14352.0.1.0)
I am having real problems getting a VPN connection set up with our network.
I have tried both PPTP and L2PT
When L2TP, I was authenticating with a preshared key
Firewall logs show PPTP negotiation successful, and issues a VPN IP address to the device
It can ping the firewall external interface, but times-out trying to reach an internal address
The VPN session is established, but the firewall logs don't register either deny or allow traffic for each internal ping request, rather the firewall packet error count increments for each failed attempt.
Any help is greatly appreciated.
I had problems with PPTP - gave up
I hate the way Windows mobile labels connections.
I connect to many customers with PC Anywhere, VNC, SSH etc and I have access via serveral different windows PPTP VPN.
Like you I setup the details in connections and try to dial.
Nothing seems to happen. The connect option does not change to disconnect. So I assume it is not connected.
I have a feeling these connection do not work over WIFI. and perhaps work over T-mobile 3g only, to maximise data revenues.
Seems very buggy to me. I would really like someone to post a working example/Instructions. Can I get a refund on my MDA PRo?
MS please note it is not a connection to my work or an internet connection it is to a customer for remote support, likewise I often connect remotely to my home via PPTP from my office.
confirmed VPN works over t-mobile 3g not Wifi
SEems the VPN links only work over 3g not Wi FI.
I'm using a PPTP connection over either 3G of WIFI depending on te active connection.
- When WIFI is active the PPTP connection connects using WIFI (I can switch off the phone, so it must be using that one)
- When no WIFI connection is active it automatically connects to 3G first, and than starts the PPTP session
In network management I'v set:
Internet:
Internet (the one containing the 3G connection)
select 'this network connects to the Internet' on the proxy tab.
private network:
My Work (the one that contains the vpn connection)
do NOT select 'this network connects to the Internet' on the proxy tab.
So as you can see, nothing special (I'm using a Qtek 9000 with standard Wm5 ROM)

VPN through 3G problem

I have problem with VPN connection to my privat network.
VPN connection works if I am on cable, wifi, but whan I am connected over 3G, HSDPA, than my connection works for about 5 seconds and than I hear sound from WM6 side that my 3G connection was broaken.
I can go to WM side and try with VPN connection there and it wont connect. But strange thing is, that if my VISTA is shutdown than I CAN connect with WM6 to my VPN server.
Please help if sombody had the same problem...
bye

I setup Hamachi yesterday on my Shift, on both the WM and Vista sides of the device and it worked perfectly. Of course, each "side" looks like a completely different node on the network, but it was really cool to remote desktop into my home and office machines from VM.
Regards,
Dave
Which VPN client software and version are you using? Or is this window PPTP vpn?
I had some problems with Cisco VPN Dialer client and the pasword manager function of the finger print reading software. Once I turned off the password manger function both the VPN dialer and finger print reader are happy to coexist. ( issue might not be problem if you are not using a RSA fob like I have to)
I am using both on my shift Cisco VPN for work and the Windows PPTP connection to reach my home network. So I can confirm that they both work from Vista and that windows PPTP works from WM6.
Nothing special, just window PPTP vpn client. My internet connection works perpectly, but when I make a VPN connection, 3G just drops the line and than reconects when I disconnect VPN connection... But VPN is allways working for about 5 seconds, a few successful pings...
I just used the magic button FN+F3 and whn vista come up i have the same problem. That means that tre problem resides somewhere in WM part. I am still looking... The problem could be that my service provider and my contry are not on the shifts list, so there could be some connecion settings problems... On my other sony vaio the same data card and HSDPA connection and VPN works OK.
Now I am playing with WM side. I can establish VPN connection to my server, bat as soon as I try to send over some data it simply diskonects 3G connection and that establish it again, without VPN connection afcourse.
So my connection to VPN is working, but when I start internet explread try to conect to any web site, 3G connection restarts.
Any suggestions or somthing....

Hi.
Is there a fix to this? I am getting exactly the same problem. 3G works for surfing on vista and exchange push/browsing on WM side - As soon as I put a pptp VPN across to the work network, the 3G on the WM side drops, and if I am looking at m network connections in Vista, the "LOCAL AREA CONNECTION 2" network "card" disappears from network settings and the VPN stops.
If I disconnect the VPN, the 3G connection restores itself and I can browse again.
any help appreciated as I need pptp to work so I can ditch my laptop!

Have you tried going into the TCP/IP properties of the VPN connection, then 'Advanced' and removed the tick from 'use default gateway on remote network'. That fix the problem for me.

Yes, I did that, but then the internet works fine and the VPN and the 3G stay up okay, but everything seems to go to the local internet and nothing goes via the VPN tunnel.

Hi,
Probably you have to change the MTU settings in the Local Area Connection, here's the command:
netsh interface ipv4 set subinterface "Local Area Connection" mtu=1440 store=persistent
1440 is only a suggestion. If you low more the MTU you will notice a decrease in speed/bandwith but 1440 will be unnoticeable and will let VPN connections work.

Have you actually got a VPN session working? From what I can see, the problem is the way that the Vista side uses the modem.
If I do a route print from Vista with the VPN up, it doesn't add any routes, so sends all traffic to 192.168.160.1, which appears to be the IP of the modem/WM side of the device.
If I manually put in
ROUTE ADD 0.0.0.0 MASK 0.0.0.0 192.168.99.1
Which is the IP of the VPN router, all traffic gets routed out down the VPN and it works for about 5 minutes, then the "Local Area Connection" network card in Manage Networks, disappears. If I then drop the VPN (because strangely it stays up) the LAC card comes back...

I didn't tried to establish a VPN with my Shift, but I found this MTU problem with many GPRS and 3G connections when establishing VPN (PPTP and also IPSEC ones).
I don't see how to help you more, sorry

vista utilizes ICS from WM6 to get the connection. that's why you see 192.168.0.1
We had a similar problem with Cisco VPN Client constantly disconnecting when using 3G Cards. We use a Cisco ASA 5510.
One solution is to disable the Keep Alive function in the ASA for the specific VPN Profile.
Hope that helps!
Try your Networks VPN APN - it could be an IP conflict.
I tried cisco vpn client over hsdpa and it worked.
I still have problem connecting with microsoft PPTP client. After few seconds connection vista-wm just drops and comes back again when PPTP client disconects.
Problem is ICS from WM6 in my appinion...
Please help me
