Remote access to license server behind NAT

Post by hyperknot » Wed Jan 30, 2019 11:51 pm

I am trying to solve remote access to an Archicad / Codemeter license server (running Windows) in an office. The client program (on remote computer) needs to connect to a single TCP port on a server, where it can continuously check the license while it's in use.

To make matters a bit more complicated, this server is behind an ISP level NAT, thus direct TCP connection to this port is not possible.

Can I use SoftEther to solve this? As I understand two problems needs to be solved:
1. Allow a VPN behind NAT, but this is a strong point for SoftEther, isn't it?
2. Configure clients in such a way that every network traffic is routed like before, except for one single port to one single server.

It's mostly point 2. which is difficult for me. Can you help a bit about understanding that? Do I need to configure the server or the clients for this? And if so, how?
