Is there is an easy way to make a LAN server?

[SELECT ALL] Code:

logging started: console(INFO), file(INFO, "serverlog_20100621_23.55.21_local#28
763.txt"), syslog(DISABLED), timestamp(DISABLED)
logging local AssaultCube server (version 1041, protocol 1128/104) now..
read 39 map rotation entries from 'config\maprot.cfg'
read 0 admin passwords from 'config\serverpwd.cfg'
read 2 (2) blacklist entries from 'config\serverblacklist.cfg', 0 errors
read 0 + 0 entries from nickname blacklist file 'config\nicknameblacklist.cfg',
0 errors
dedicated server started, waiting for clients...
Ctrl-C to exit

WARNING: could not connect

...Yeah.
(Scrollbar, by the way)
I can connect to the server it creates, and others on the LAN can see it and it's stats (that it's a deathmatch, what the map is, etc,) but nobody but me can actually connect.

I was going to use it for a game between three people all currently staying at my house, but in my day, I have set up several LAN games on a school connection... x3
