I am running a properly-configured OpenVPN client on Windows Vista (the same config has worked on other computers). I'm using OpenVPN GUI 1.0.3.

I seem to be properly connected according to OpenVPN UI:

ipconfig shows that I am connected to my work network:

Ethernet adapter Local Area Connection 2:

   Connection-specific DNS Suffix  . : hq.myworkplace.net
   Link-local IPv6 Address . . . . . : fe80::25aa:1764:3f5d:9c70%19
   IPv4 Address. . . . . . . . . . . : 10.0.2.10
   Subnet Mask . . . . . . . . . . . : 255.255.255.252
   Default Gateway . . . . . . . . . :

If I launch Remote Desktop Connection and try to connect to a machine, it fails. I tried to connect by using machineName and my using hq.myworkplace.net\machineName. Pinging that machine also fails (ping machineName, and ping hq.myworkplace.net\machineName error with "Ping request could not find host machineName")

I have a feeling that my wireless router is also causing some problems.

Any suggestion as what I could do next to troubleshoot this?

Thanks!

well - as your log says - you have route conflict - your home subnet overlaps with corporate private address range. if possible try readdressing your home network and use for it something from 192.168.0.0/16 or 172.16.0.0/16 ranges.

Thanks I set up my home network router to use 172.16.0.1 and now I can ping machines and remote desktop into them –  cocowiki Dec 3 '10 at 7:22
