VPN driving me mad!

Over the last year I have tried many times to set up my Windows Mobile devices to connect over VPN and then use RDP to manage my clients' sites. To date I have never managed to get it to work. My config is as follows :-
Within Start \ Settings \Connections \ Advanced \ Select Networks
Programs that automatically connect to the Internet use MY ISP
Programs that automatically connect to a private network "My Work Network"
a VPN is configured under "My work network" and the device can connect to this and using vxutil I can ping the server I wish to RDP to - 172.17.3.3
Supposedly the important bit is to add the exception under "Work URL exceptions", I have added 172.17.3.3 in here.
Once the VPN is established if I enter 172.17.3.3 within IE or Terminal Services CLient the VPN connection is still dropped.
If I enter this IP address without connecting the VPN first then the device will not connect the VPN automatically.
If I enter a non qualified domain name such as ids-vs then the VPN is connected but the name is never resolved.
Can anyone shed any light on this, if I could use a local lmhosts file on the device as with XP then I may be able to work around the above. It appears to me though as though the exceptions list is never processed. I did a hard reset last night just in case, but this has made no difference.
I cannot believe that the above can be so complex.
I am using a HTC Tytn and using t-Mobile in the UK.
Any help greatly appreciated since it is driving me totally mad!

I would love to figure that out.
I was trying to connect to my pc at home like this and suffered from all the same symptoms your having. In the end I gave up, mainly 'cause someone told me that I needed another type of data plan to have vpn (at the time I had the $29.99USD plan) in other words it might be your plan, or something to do with the proxies or something, I hope someone would find out what you need to do in order to get this to work.

It's strange, looking around the web there are loads of people that struggle with the setup, but most seem happy once they are told to add the server name or IP address in the exceptions list.
I have ruled out the data plan since I can establish the VPN connection and can see it authenticate on the other end, as well as being able to ping the server on the work network from the phone.
I have just opened a support call with Microsoft as well, but I am not holding out much hope since I think they will point me at HTC. Assuming HTC ever responded they will just point me back at Microsoft!

Well it would be cool if they could help you, I tried everything myself and zilch. I could also establish a connection but as soon as I would try to access a file on my pc it would disconnect. I would try to help you out experimenting on my side again, but I changed my router to a cheap piece of $h.. and now I can't access my pc via vpn..... I really need to get a decent router
This may sound stupid, but I could swear someone told me something about the speed of the connection. If the connection speed is too low then DNS would fail, although that wouldn't explain why we are able to establish a connection, but not access anything else.

OK, I have made quite a bit of progress :-
1) I was using a cab file to configure T Mobile settings on the phone. This was somehow configuring the exceptions list to be ignored. Hard resetting the phone, installing this CAB the problem remained. Hard Resetting the phone and setting up GPRS manually - everything worked.
2) There is a fault with Windows CE 5 routing over VPN - the subnet information is ignored. Hence for example, if your GPRS provider give you a NAT 10.x.x.x ip address and your corporate network uses 10.x.x.x then you can never route to your corporate network.

And what cab file is that? do you know if it's on the extended roms for the t-mo roms? Glad to see your making progress, keep it up.

It was a Cab file for the Tmobile settings. It either came from these forums or over at modaco, can't remember which.

VPN
I was able to successfully use the Movian VPN to connect to my work using my XDA2.Worked fine for 2 years. Apologies, but I can't help with the settings and my work migrated to an M-notes server so I was able to connect without a VPN.

How to connect to my univerisity wireless network?

Hi there
I want to connect to my universities wireless network.
The requirements the want are;
Root Certificate installed (I've already installed)
a client device that supports the wireless authentication mechanism, 802.1x/PEAP. (This bit is which I am not sure that the Exec has)
----------------------------------------------------------
Part of the configuation instructions provided by the university
Network name (SSID) = ****-student
Network Authentication = WPA
Data encryption = TKIP
If you do not see an option for WPA then the
software for your network card might need
updating. Please consult the manufacturers
documentation on how to do this.
---------------------------------------------
Is there a way that I can get a patch or something or is it still possible to access my universities wireless network?
I've got a o2 XDA Exec
Many thanks for your help guys

In my previous university, the MAC of the WiFi network needs to be registered before you can use it, even you have all the username or password. First I didn't notice this because other friends got their notebook connected without registering their WiFi cards. And only later, I notice that since they bought their notebook via the university, the MAC is already registered. Double check with your uni IT guys.
Also, check if they have WiFi B support. You may need to check if your phone is capable of using G. There are solution for *some phone to enable G, search.

OK it seems to connect but I need to install my university root certificate on my universal.
How do I do that?
Thanks

Logmein.com "Mismatched IP Address" (Solved)

Found the problem!
This problem was being caused by the Blackberry Service on my device. In further investigation I discovered that whenever the Media Net connection goes stagnant the Blackberry connection would reestablish & try to check for new emails. The new BIS connection would change my IP to communicate with our Enterprise Server & of course subsequently, Media Net was killed. When I would try & re-establish my logmein connection it would report the new IP which was hung on Blackberry instead of being reset by Media Net & would report as Mismatched for security reasons.
The solution:
Whenever I need to do some work on my desktop remotely I now suspend the Blackberry Service & have now had no problems with logmein, even through reconnects.
Thanks for all the IM's & emails, there were some interesting ideas
_________________________________________________________________
For years I used logmein with verizon's network without problem. But now I'm AT&T & every time my connection resets I get an error stating "Mismatched IP Address" causing me to have to shut down PIE & start over again.
I have read about a broken proxy fix meant for other client laptops & pc's. I have imported my own"broken proxy" reg.value into logmein security registry settings on my Kaiser. However, every time I lose connection, I still have to start over. Anyone else have this error before?
I'vd tried everything I can think of. Any help?
Thx!

i believe it has to do with using wifi instead of edge/3g. I had the same problem when i logged on with edge and then tried to access my computer with wifi after already logging in to the system. I dont know of this will help but i just relogged in and accessed the pc using the same connection type.

negative, it happens using 3G, edge, gprs, etc.
I thought maybe I could enter an IP in connection settings but then I can't connect period.

Hi, I know this is an old thread, but I'm getting the same error message on my HTC Touch HD (Win Mo 6.1) - any ideas as to how the specified solution could be applied to my device?
Thank you.

Network settings issue with my Titan?

I have a xv6800 with DCDs latest 3.0.1 ROM. I'm able to connect to the internet via Verizon wireless and via my Wifi but I think my network and/or security settings are a little out of whack.
First, when I connect the xv6800 to my computer via USB to perform an active sync the following window pops open on the xv6800:
Pocket PC Networking
Cannot obtain a server-assigned IP address. Try again later or enter an IP address in Network Settings.
I have no idea what it's trying to connect to or why it needs an IP address.
Otherwise the activesync runs fine (it syncs up and I can transfer files without issue).
Secondly, when I try to open the "Video Sites" html file that installs along with FlashVideoBundle.cab package, I get a security warning stating that the page cannot be opened because it wasn't signed, etc... and even more recently, that page just locks up PIE (it appears as if it's constantly trying to reload it).
I'm not sure if the two are related but I'd really like to get them resolved.
All the xv6800's network adapters currently are assigned to connect to the internet and have the "use server-assigned IP address". Is this correct?
Thanks for the help!

WiFi Connected but No Internet - I FIGURED IT OUT!!!!!!!!!!!!

Here is basically a run-down of what I did. I hope this helps everyone out.
Device specs:
Samsung Galaxy Player 4.0 Rooted
Network Specs:
DSL Modem
Router (DHCP with WPA security and does not have MAC Filtering)
4 Access Points (all on same channel broadcasting same SSID with same WPA security DHCP)
2 Servers - Static IPs
-Server 1 - DNS (not sure if it is actually a DNS server or just forwards the requests). Also storage/application server.
-Server 2 - Storage/Application/SQL server
Many clients on network (unsure of total amount but somewhere around 30 would be my guess)
Problem (note this is only on this network, every other network wifi
works just fine):
Wifi Connected but no internet.
My Windows 7 laptop (same network) gets internet access with no problems
No reports of any other clients on the network having this issue
Device has assigned a good DHCP IP address
Subnet, Gateway, and DNS IPs are all correct (they match the ones on my laptop)
Connection strength is great (speed is 52mbps)
Device has full local access (intranet). It can access all files and other devices on the network.
On occasion the device will get "internet" access for a brief period of time but will go back to "intranet" access only after a few minutes.
Tests Performed (My android device will be referred to as "device" my laptop will be reffered to as "laptop". All tests were performed with both laptop and device connected to the network in question, unless otherwise specified, and device was not able to access internet):
Ping from laptop to device - Successful
Ping from device to laptop - Successful
Ping from laptop to gateway - Successful
Ping from device to gateway - Failed
Resolve DNS IP on device - Successful
Resolve DNS IP on laptop - Successful
Ping from laptop to google - Successful
Ping from device to google - Failed
Small FTP file transfer from laptop to device - Successful
Small FTP file transfer from device to laptop - Successful
Device has no problems on other networks (tried un-secured, WEP, and WPA/WPA2)
Connect device using Google public DNS servers
-Intranet - Successful
-Internet - Failed
-Resolve DNS IP - Successful
Connect laptop using Google public DNS servers
-Intranet - Successful
-Internet - Successful
-Resolve DNS IP - Successful
More that I cannot remember right now. Will add as they come to me.
At this point I gave up for a few days. Every test and every bit of research returned nothing. I had spent many many hours trying to figure this out and testing theories and nothing ever pointed me in the right direction of where to go. Nothing made sense EVERY single setting is the same is on my laptop. Started thinking maybe there was something in the router that could be blocking Android devices (since it is a work network). Although I am not a aware of a router feature to do that I figure I would try some more tests.
Testing Round 2 (same conditions as initial tests):
Configured laptop to be a Wifi hotspot.
-From CMD command 1: netsh wlan set hostednetwork mode=allow ssid=AP key=XXXXXXXXX
-From CMD command 2: netsh wlan start hostednetwork
-From network and sharing center: Shared the physical wireless network connection with the Microsoft Virtual WiFi Miniport Adapter.
-The above commands create a virtual wireless adapter and set it broadcast the specified SSID with the specified WPA security key. Then you can choose any available, connected, physical, internet connection and share it's internet connection with the virtual connection, thus theorectically turning my laptop into a 5th access point on the network.
Connected device to the SSID "AP"
-Intranet - Successful
-Internet - SUCCESSFUL
Horray!!!! Progress! So with the above information I went to our IT guy and we sat down and looked at some stuff (settings in the router, access points, and servers). After digging and digging around within the settings we came up with.... you guessed it NOTHING!!!!!!!!!!!!! Now I was in "Its on!" mode and decided I wasn't going to stop until I found out at least what was causing the problem. My IT guy was also very determined to figure this out as he doesn't like to get beat either. So we both went at it. We decided the first thing to do was make a very detailed network map containing every piece of information we could possibly find. We did this all from his machine (laptop with Windows 7) and wrote everything down on paper (we even used a piece of our 36" wide roll paper from our plotter to make sure everything would fit) and made an excel spredsheet with all the info. Now with the newly aquired network information I decided I was going to do more testing.
Testing Round 3 (same conditions as initial test):
Map the entire network again gathering every piece of information possible just like before but this time using MY DEVICE (not my laptop).
Compare
Finally! I have found the problem! As stated before my device was getting the correct gateway IP (XXX.XXX.XXX.1) which is the same as my laptop). However the assigned MAC address OF THE GATEWAY (router) to my device is XX:XX:XX:XX:XX:FB but the MAC address OF THE GATEWAY (router) to my laptop is XX:XX:XX:XX:XX:FA. Got back with our IT guy and we found (by looking the router config) that the XX:XX:XX:XX:XX:FA is the LAN MAC address for the router. The XX:XX:XX:XX:XX:FB is the WAN MAC address for the router.
Testing Round 4 (same conditions as intial test):
Connected laptop to network, confirmed XX:XX:XX:XX:XX:FA MAC address was assigned for the gateway by running "arp -a" in CMD.
-Pinged google - Passed
-Changed assigned MAC address of gateway by running "arp -s XXX.XXX.XXX.1 XX:XX:XX:XX:XX:FB" in CMD
-Verified new MAC address assignment by running "arp -a" in CMD
-Pinged google - Failed
-Changed the MAC back and pinged google again - Successful
Connected device to network, confirmed XX:XX:XX:XX:XX:FB MAC address was assigned for the gateway by running "arp -a" in Terminal.
-Pinged google - Failed
-Changed assigned MAC address of gateway by running "su" then "arp -s XXX.XXX.XXX.1 XX:XX:XX:XX:XX:FA" in Terminal
-Verified new MAC address assignment by running "arp -a" in Terminal
-Pinged google - Successful
-Changed the MAC back and pinged google again - Failed
Conclusion:
For some reason the device is getting assigned the correct gateway IP but the wrong gateway MAC. This is allowing the device to connect to the network but not communicate with the router. Since it can't communicate with the router any "Internet" requests time out because the packets have to go through the router to make it to the "Internet". Since it is not blocked from the network it can still connect and communicate with other clients on the "Intranet" but not the router.
Our IT guy thinks there is a client somewhere on the network in the same subnet that is configured in this matter and it just so happens that for some reason my device is picking that up when it connects. He is going to look into it more when time permits but since we are very busy and we have already spent way too much time on this, and I now know at least what the issue is, he is going to move on for now.
Why would my device be picking up the WAN MAC address of the router?
What would be responsible for assigning a WAN or LAN MAC address?
How can I prevent this?
Has anyone ever experienced anything like this?
Temporary Solution (must be rooted):
Open your favorite terminal app on your device.
-Enter "su" (without quotes)
-Enter "arp -s [Your gateway IP here] [Your gateway's LAN MAC address here]
Browse away!!!!!

Hello.
I had the same problem, that I could connect to router but had no connection to internet.
Read this post and started to do some research on my router. When I configurated my router, there was an option to clone MAC address. And of course to get it done fast I cloned MAC. And now I checked that it cloned my laptop MAC. Changed MAC from laptop to Routers MAC (must be on label under router) and got a really nice internet connection.

Hi, I think I have the same problem with the same device, Samsung Galaxy Player 4, but even if my device is rooted I still can't excecute the "arp" command from the Terminal application (there is no "arp" command). How can I check/modify the arp list on my device???
I really appreciate your help. Thanks in advance!!!

I use the terminal emulator app. It works just fine for me and I never had to download any other software to be able to run the ARP command.

anyone found a solution to this ?
just updated to ics4 and cannot connect to the internet.

You only have one device that assigns IP adresses, right?
How about changing the channel to see if that works? or maybe even the security protocol

the only thing that worked for me is to turn on the dhcp option
in my router. previously, i was using static ips

I had the sams problem. I could connect with my wifi but had no internet acces. The solution here was the wifi encription.
My smartphone could not encript the hard encription I think. With WEP encription it all works well.

Hey guys,
Here's a run down of the problem I'm currently having. A few months ago I purchased a Dapeng A75 currently running ICS 4.0. Although a beautiful and fast phone, just recently it started going out of wack.
- Youtube and Play Store hang on "Loading" screen
- My Gmail accounts won't sync
- I can no longer search on Google.com with ANY browser through WiFi. (I do not have data service on my phone)
I've tried several attempts at troubleshooting this, all which have failed.
- I restored my phone to factory default.
- Uninstalled and reinstalled these apps.
- Downgraded the apps to previous versions.
- Cleared my cache on just about everything.
- Release and renewed my IP in Terminal.
Just recently I noticed a CWM recovery image posted and I figure this is the only solution. Wiping out the phone and flashing a fresh ROM but unfortunately I can only get as far as installing the drivers to my Windows 7 machine. Some reason when I plug the phone in after installing the drivers, Windows will prompt me that the device is plugged in but before I get a chance to hit F9 for SP Flash Tool to do it's thing, the device quickly disconnects.
NOTE: I am able to browse Google via WiFi only by using HotSpot Shield VPN (Which is problematic in itself).
I'm currently losing the battle with this phone and at my wits end. Is there anyone out there who is experiencing the same situation or has some sort of solution which doesn't involve be shelling out more money for a new phone?

good work brother
i understood the above problem n i too experienced the same problems so now i will take ur research to next level n see my know of network .
i appreciate all the work done you , in research of this LITTLE but hetic problem.
i have learned a lot through u r research.
n will do more n keep u guys posted if i found somthing on this

i would like to add if u have seen the
cmd-ncpa.cpl-ipv4-propreties- in this section u see its Dhcp so all fields are inactive
but u can see gateway ip which is inactive such as in my case 192.168.1.1
u cannot remove that.
any body saw the reply....
thanks regards
