Alright so you have to dig deep into the archive files to find something like that since most people already know how to change the files ip's and such to make it available for other computers to connect. You are lucky since i saved you the time by looking it up myself (was actually to remind myself on how to do it) what i found is one of the thread where i had a port forwarding problem but found out it was my computers problem anyways

the second post by Tigress is the one you have to look out for it shows you have to change ips in your inin files, check the port in your neuz and portforward for that on your router, and also check your cacheserver.ini files.
Yeah the website based setup is something i dont actually have much experience with since most of the time im just making a map or doing something ingame lol.
