Hello, you can actually setup your server on another PC/server, but you will only still be able to play solo, like if you had the server on your main computer.
Tho, you will have to manually install the server certificate on the PC you want to play on.
If your PC is on your local network, you wont need to change the IP afaik, and should work with the local IP.
If you try to run it on a server, you'll have to change the IP through either AkiConfigurator or in server.json, and specifically on linux, you'll have to make some changes to the sources, as there's uppercase letters sets for lowercase filenames and such.
Any if you want to change your port, you can aswell use AkiConfig like said in the FEI post, despite what people are saying about it, it does work as intended.
