PPTP VPN Issues - HD2 Android Q&A, Help & Troubleshooting and Genera

Hi,
I am having problems getting VpyrVPN or any VPN to work on my current setup. I can create the VPN profile from within android and it connects fine. However after the tunnel is established (and I can see this as ppp1 in system info) no traffic appears to route down the tunnel. Everything still defaults to go over the standard 3G routing.
For example if I go to whatismyip.com I retain the IP address of the telecoms provider. This is not the case when testing on a wifi connection as it works fine.
I am running MDJ Desire HD v4.3.
I have tested VPN access via my provider on 3G by tethering my laptop to my HD2 via the Android "Wifi Hotspot" app and it connects fine on the laptop and routes down the VPN as expected.
Is this a known problem with froyo or could this be specific to using PPP rather than RMNET? Or is there a fix?
Your help would be greatly appreciated.
Kind Regards,
Ross

VPN over WiFi connection

Hi
I searched the forums for info, seems that others have had issues trying to connect a VPN session over WiFi. Basically, my wifi (internet) is connected, the 'Connect VPN' option appears in the 'Connectivity' bubble, but tapping 'connect vpn results in the unit trying for a while to connect and then giving up with no error.
Probably yet another XDA bug. My device is the XDA IIs (Blue Angel).
Anyone got a VPN going over wifi?
For the record, it (VPN) works fine over GPRS, although the implementation is shockingly bad. You cant hit boxes on yr lan via IP, it drops the VPN the moment you try. I guess i'll have to set up some hosts file to fool the sack of crap into realising that it needs to head down the VPN to get to said ip.

Check your ip's, they must be in different subnets at each end of the vpn eg (192.168.1.--- >>>><<<<192.168.0.---). If they are both in the the same range then packets won't be routed correctly.
I use vpn over a wifi lan every day, and it works like a dream (on an xda2 with soket wifi card).
Hi
Yeah, they are in different subnets, still refuses to connect. God knows. The wifi implementation on the Blue Angel is bugged to hell so I suspect this is just another bug.

I can get my VPN to connect.
My M2000 is connected to my local lan via wifi (192.168.0.0) and I have set up a VPN to my work lan (172.16.0.0).
The vpn connects and shows as connected in the connection dialog bubble.
However, I can't see/ping anything on my work network.
The PPTP NDISWAN Miniport adapter shows as not connected.
Using xvIpconfig i can see that there are two active adapters.
One is my wifi card...all ok there.
The other is called RAS VPN Line 0.
It seems to have a correct IP address, subnet mask and default gateway for my work network but it says that DHCP is disabled.
Also the adapter address is 00-00-00-00-00-00...that can't be right can it ?
VPN
hi guys, have you made any progress with the vpn and the blue angel. I am having the same problem - VPN appears to connect fine and then drops without any errors etc. to make matters worse i deleted all 02 connections so now i can't even see the vpn connection. Help!!!

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 - Only through Wi-Fi?

Hello,
Hopefully somebody can help me on this one because it is absolutely driving me nuts and I can't find a shred of information on it anywhere.
I have an L2TP VPN setup for work and it works great if my phone is connected over Wi-FI. However, I can't get it to work over the cell network. When I hold down the VPN entry and click "Connect" it waits about 3 seconds and brings up an error saying "Cannot connect with current connection settings. To change your connection settings, tap Settings". If I tap "Settings" it just brings me back to my VPN entry. Again, this works flawlessly over WiFi so I don't believe it's an issue within the settings of my VPN connection.
Is there a registry hack I need like the "ForceCellConnection" key used with tethering? Am I supposed to create a Modem entry in the VPN settings? I've tried this and copied the properties from the default "Sprint" connection but that doesn't work.
Thoughts? Ideas?
Thanks,
Scott
sounds like your phone company are blocking the ports required for vpn try connecting them

Have you heard of Sprint blocking VPN? Also, this worked fine on my old Touch Pro Diamond but hasn't worked since I got my Touch Pro 2.
Thanks,

A similar issue
HI
I have a similar issue
Using windows mobile 6.5 device with a Vodafone 3G sim
Connecting to a draytek vigor 2820 router setup with basic PPTP
the wm6.5 device will connect to the 3G network but the VPN does not connect.
if I turn the 'phone off and turn on wifi, the same VPN settings allow me access.
Conclusion: VPN settings are OK
Using windows xp PC with the same Vodafone 3G sim in a USB dongle
Connecting to a draytek vigor 2820 router setup with basic PPTP
the Windows PC (wifi off, network cable out) will connect to 3G and also connect using PPTP to the VPN
Conclusion: Provider (vodafone) is not blocking the ports.
which leads me to think that the problem resides in the VPN client on WM6.5.
however I'm not sure where to go from there. Have I missed some setting? does it even work? any assistance greatly appreciated.
best regards
Stuart
i think this is the script blocking by the phone company
Try connecting via hostname/IP address in the VPN setting.

PPTP VPN not working?

Hi Guys,
i have access to a few VPN servers incl. my own in Europe and a few strong VPN accounts.
But once i connect with PTPP VPN - i get a little traffic back and then it stops completely. I do not have problems with other platforms (Mac, PC, iPhone etc)
It happens both on WiFi and 3G etc.
Anyone have VPN working?
(Firmware .16 UK Generic)
ohh - and L2TP can't negotiate security with my router from the X10 - rest of my devices can..
Damn this X10 is full of issues.
its broken completely
i can get it to connect to witopia via 3g, no traffic in and out
turn on wifi, wont connect at all.
VPN for X10 as it stands is DOA
seems like it is a known problem even in A2.1
http://code.google.com/p/android/issues/detail?id=4706
I made a new profile on my Mikrotik Router - that allows connection without encryption - and that seems to work for now.
But my SIP does not work - getting a lot of microphone feedback - from Fring, SipDroid and other SIP clients :-(
@klarsen
How did u get pptp working ??
my X10 wont connect to my Bintec R1200 Router
My Ipod connects without problems using Wifi and my Iphone connects over UMTS. My X10 is unable to connect.
The Buildin PPTP Client is very very trashy. There are no settings for encryption exept "on/off". PPTP uses serval encryption methods. The same with the authentication. The Error Messages are such as useless.
I Tryed to switch off encryption, tryed all authentication methods (none,PAP,CHAP,MSCHAPv1 (v2) )
What i need to enter in "DNS Searchdomains" ??
But the phone says, it cant connect to my network. I Tryed it over UMTS and over the Wifi Accesspoint from my neighbour.
Why the Linux&Co Guys are not able to write an PPTP Client like one on the Iphone or in Winmobile ? Some Touchtaps and the tunnel is Up.
I had big trouble to set up a pptp tunnel on my Nokia N800 (Linux Maemo) , too.
Greetings

Openvpn on Samsung Galaxy S I9000 - Gingerbread

I've been trying to get my Galaxy to connect to my Openvpn secure network.
I am using a DD-WRT Linksys server which is working well with several different Windows clients.
After trying several different installation variants, on the droid, I've settled for a Voodoo kernel which has the tun.ko module already included.
I'm using Openvpn Settings from the market to enable and run the OpenVPN
During connection, it does everything that you would expect and gets its tunnel IP address from the Openvpn
When I connect the Galaxy I9000 to WiFi everything is "hunky" and works well - the 3CX app connects to my 3CX VoIP server perfectly.
However
When I disconnect the OpenVPN and connect the phone to 3G (Vodafone UK), again everything connects and I get the appropriate IP addresses.
The 3CX client also "registers" its SIP with the 3CX server but doesnt seem to handle any RTP packets.
Also, if I try and browse to a web server in the LAN, it works with the WiFi connection but not the 3G
Now another strange thing.
If I set up tethering - to get a WiFi connection for my Windows laptop.
And then run OpenVPN client on the Laptop - everything works even through the same 3G connection of the Galaxy i9000.
Any ideas???
All resolved now
In fact Openvpn was working fine.
It was the VoIP/SIP app that wasnt working properly - all fixed now by changing parameters on the 3CX VoIP server.
Also browsing to internal LAN webservers wasnt working - downloaded a copy of Firefox for the Android and all is fine - I think the other browsers (Opera etc) have some kind of proxy that they operate though - if this is so, the proxy is probably outside my OpenVPN LAN
i like how questions are always in the right section
