OpenVPN Support Forum

Posted: **Tue Apr 03, 2012 3:29 pm**

Hello,
I have a strange problem which I think is more likely a Windows issue.
The config I have is an office with an Ubuntu server running openvpn (as a server) and also a windows file server.
My first and second laptops CAN CONNECT and browse the windows server (using the IP address).

My problem is that the third laptop can connect and PING the server, but fails to access the file shares using explorer.

Please Help !!

Are you pinging the file server by name? How are you trying to access the shares?

No by IP address,
at the command prompt, this woks

Code: Select all

ping 192.168.0.3

but in explorer, this does not

Code: Select all

\\192.168.0.3

Just to be clear this is only on one out of three laptops

Thanks

Your first problem:

OpenVPN.exe and OpenVPN-GUI.exe need to be ran as administrator

Your second issue:

No by IP address,
at the command prompt, this woks

Code:

ping 192.168.0.3

but in explorer, this does not

Code:

\\192.168.0.3

Just to be clear this is only on one out of three laptops

Thanks

Note that this may be resolved by the solution for the client issue above. I don't see a route for the 192.168.0.0/24? network being pushed by your server. Try adding this line to the server config:

Code: Select all

push "route 192.168.0.0 255.255.255.0"

I have checked (and double checked) that the user is running "As Administrator" - and they ARE.

When I saw the errors you pointed out, I was confused - the "route print" command shows an entry for the 192.168.16.0 network, and the PING command does work.

Also, my apologies, the commands I showed had the wrong subnet

, they were
ping 192.168.16.3
and
\\192.168.16.3
