openvpn

We have this machine that we RDP into for using OpenVPN. When a tunnel is connected, it is not possible to RDP into the machine. Should we get disconnected, this is a problem (machine is headless).

How can I stop OpenVPN from blocking inbound RDP?

I do not have access to the server configuration. If there's anything interesting on the client to check you'll have to tell me how to get at it. I eliminated the possibility of routing issue before asking the question. Only inbound connections cannot be opened. Outbound connections to LAN can be opened just fine.

EDIT: Don't bother answering. The problem disappeared without any known changes being made.
