hi there,

i noticed in your client config:

remote 10.32.89.24 1194

and in your server config

push "route 10.32.89.0 255.255.255.0"

why are you pushing such a route???
please remove it,
also what version of openvpn are you using on your windows?
are you running the gui with admin rights?

I am using OpenVPN 2.2.2 latest one
and yes i am running OpenVPN GUI 1.0.3 as administrator.

currently i am try to access the server using openvpn from inside network.
internal address for the server is 10.32.89.24 thats why i wrote that in my client config.

push "route 10.32.89.0 255.255.255.0"

I am pushing that route because usually i access the server from outside the network.

One more think i want to point out is When my employee use linux computer to connect and access from outside network it works perfectly fine. It seems this is Windows Specific. and uptill now i am trying from Windows7 Pro 64bit machine. from inside and outside of the network.

FYI:OpenVPN & Server are same machine.

One more thing i figured out from the log file.
that previously when i was able to connect and access the server
my TAP-win32 Adapter has a Index = 27.
now it is Index = 20 everytime i connect.
What this Index mean? is Index make difference for ping and accessing the server?

when you are in the same network you dont need to push this route push it only
when you are outside.

can you post the output of netstat -nr after you connect from outside?
