Strange problem using vpnc widget - HD2 Android Q&A, Help & Troubleshooting and Genera

Can't get VPN to work through my local wireless network. What is strange is that when I connect through mobile data, or any other wireless network available, everything works as it should. Also, vpn connection works from local PC too.
When I try to connect at first it seems like it went okay, as it shows up green and "VPNC is ON!" but, I have no connection to the network, can't ping / trace anything on the vpn network.
My local subnet is 172.25.1.x and VPN is 192.168.0.x but as I mentioned before, same thing is on local PC where it works fine. IPsec Passthrough is enabled in my router configuration.

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)

debugging wifi/vpn issues

Hello,
I'm having issues to connect my TyTn to the wifi/vpn at work. The first time I set it up, everything works perfectly (pda connects to the wifi, when an application needs network, connection to the vpn is made).
However, when disconnecting from the network, and connecting again (even if no other wifi network has been accessed), the vpn connection is not made. The vpn server is visible (via ping), and all settings are the same.
How can I start to debug this?
(the vpn server is not under my control )

tilt and vpn issues over edge

i have isp.cingular provisioned and can connect some of the time.
1 vpn which goes to my home network works using vista as the vpn server connection. It does not always connect the first time though.
My work vpn which is pptp on a watchguard firewall, has 5% chance of actually connecting. Most of the error messages are talking about packets missing etc... When it does connect i cannot ping servers on the network but i see that the phone has a correct ip address and dns servers from the vpn. the gateway is the same as the ip assigned to the connection.
I have the same issue using the tilt over wifi from home where the vpn does not always connect at work.
I know the work vpn is fine since i use it all the time with vista's vpn dialup stuff.
Anyone got answers or ideas?

[Q] VPN over wifi Internet doesn't work for some reason

I am able to connect to my home router's PPTP VPN server from my Android phone's PPTP client. I can even see my remote LAN devices; and, my remote LAN devices can see my mobile phone on the LAN.
The problem is when I connect my phone to wifi Internet.... BEFORE connecting to my PPTP VPN server... I can't see the remote LAN; and, the remote LAN can't see my phone. The only thing I can do successfully is get a new public IP (my home Internet public IP).
What can I do so that I am able to use my local wifi Internet connection to connect to my VPN at home?
It might be a route problem.
When you connect to WiFi, some static routes are pushed to your phone.
Those routes might not be refreshed or conserved after a VPN connection.
If it is not a route problem it's a default gateway problem.
Yes, that's what I suspected. I already tried adding routes; specifying the gateway via command-line; however, I didn't have any luck; probably because I didn't know exactly what I was doing.
One thing I noticed; when I use my wifi internet hotspot, I noticed that it gets a private WAN IP.. 10.x.x.x; which then NATs to a temporary real public IP; which no connections instigated from the outside world can make it So, even if I do port-fowarding on my wifi hotspot router, it doesnt help any since the incoming connections are stopped dead in their tracks.
I'm using PPTP VPN; which depends on a TCP port 1723. If that TCP connection is instigated from my remote VPN server into my mobile Internet wifi hotspot based LAN devices, it wouldn't work for the same reason explained above. I didn't see a PPTP VPN passthrough option for my wifi hotspot; only for IPSEC; which I dont have a server for. I'm guessing that if I had a real-world public WAN IP for my mobile Internet hotspot, maybe I wouldn't have this problem for PPTP.??

First, are you talking about a free internet hotspot or from private internet hotspot (@work for example) ?
you'll never gonna get a public IP from your internet hotspot. 1-public-IP-for-1-client on a hotspot is just inconceivable, due to IPv4 exhaustion.
I think you only have to try to do port forwarding on your hotspot.
Your assumption "it doesnt help any since the incoming connections are stopped dead in their tracks" is wrong I guess. If your hotspot has a built-in firewall, it might be stateful. As you are initiating a connection to your server, the returned traffic flow shall be allowed.
If it doesn't work after port forwarding, try to look at firewall rules on your hotspot router.
Problem resolved.
My Verizon wireless hotspot (890L) doesn't support PPTP passthough. More specifically, PPTP's routing protocol: GRE (value 47). Verizon does offer another wireless hotspot that does offer support for PPTP; at least via a firmware update.
This issue actually pushed me to install and configure OpenVPN server on my router; instead of using the existing PPTP server which I already had. OpenVPN is fantastic is working through firewalls.
Great !
Yes, OpenVPN is a delight.
me too
I have the same problem,
but I usually change another ROM until there's no bugs

have you tried to configure the wi-fi gateway to match your vpn router?
settings / wireless & networks / wi-fi / long press your vpn connection / modify network / scroll to show advanced options / select static ip /scroll down to gateway and put the gate address in / save
I run a vpn through a 2 router setup, and even though my phone connects to the vpn router, its gateway by default is always the non-vpn router. changing the gateway to the vpn router allows the vpn to connect to the phone. you can verify the vpn connection by going to ip-score.
That why i can't see my phone using wifi in VPN network..
cant connect if theres no mobile data or load
Hi please help ..when i have load i see its connected..but if i have no load its not connecting please ..anyone can explain this?
