in your bid to boost your post count you misunderstand, i know the DEFAULT LFS ports, i was wondering if you could change them (not just for unlocking, for racing and for servers) using the full client
Using the full client you have the option of setting the incoming port for your server when you select to "start new game" in multiplayer. You can also set the IP to bind to in case you have multiple IPs.
Outgoing ports (used when connecting to a server) are random in the 1024-5000 range AFAIK.
