With OpenVPN access server there is both a tunnel network for dynamic clients and one for static clients.
How do I add a tunnel network for static clients to a OpenVPN server at OPNsense?
If I add a tunnel network outside server tunnel network with client specific overrides, the trafic is not routed correct.
You can configure a second OpenVPN server for your static clients. It has to listen on a different public IP address and/or port on the OPNsense WAN interface.

I know that I can create a second server on a different port. but I wanted to use the same server and a range that do not potential conflict if an other client get the same IP.
