I have set up an OpenVPN Server on my RUT955 and could connect to with OpenVPN Client on a Windows 7 machine.
After a reboot of the i can no longer connect via VPN.
I have set up a DNS on the RUT955 and set it in the client. I can see the right public IP of the Router.
Here are the log file when i trying to connect to the Router.
