Need to change NAT settings after restart of server

[Gornil]

Hi,

I've setup a headless server for me and some friends. When a new patch for Factorio is released I need to restart my docker container to get the new Factorio server. And sometimes I get a new external port I need to forward through my router. I need to go into the log file and look for the port it confirms on and add that to the NAT. Is there a way I can set this port permanently?

5.774 Info ServerRouter.cpp:547: Own address is IP ADDR:({xxx.xxx.xxx.xxx:54371}) (confirmed by pingpong1)
5.791 Info ServerRouter.cpp:547: Own address is IP ADDR:({xxx.xxx.xxx.xxx:54371}) (confirmed by pingpong3)
5.974 Info ServerRouter.cpp:547: Own address is IP ADDR:({xxx.xxx.xxx.xxx:54371}) (confirmed by pingpong4)

NB: I'm running Factorio Server manager and running server viewable in the Factorio MP server list.

Factorio default port is udp 34197
