install freelancer, and the patch if you want to go above lvl 38 rank, (for a modded server, install mod BEFORE the patch) if behind a router, open ports 2302 to 2304, forward them to the host machine (further details about this can be found in the read me, in in the freelancer folder)

you may also want
fladmin 1.29 (gives remote access via telnet for admin, again u may want to open port 23 on your router, details can be found in the readme that comes with it
)
ioncross flso (imroved cheat protection and edit of player files, plus much much more)

if behind a firewall, you must give all the above access to the net, or when running, no one will be able to join.

run flserver.exe
