|
Removeip will only remove an address specified exactly the same way.
|
|
You cannot addip a subnet, then removeip a single host.
|
|
|
|
listip
|
|
Prints the current list of filters.
|
|
|
|
writeip
|
|
Dumps "addip <ip>" commands to listip.cfg so it can be execed at a
|
|
later date. The filter lists are not saved and restored by default,
|
|
because I beleive it would cause too much confusion.
|
|
|
|
filterban <0 or 1>
|
|
|
|
If 1 (the default), then ip addresses matching the current list will be
|
|
prohibited from entering the game. This is the default setting.
|
|
|
|
If 0, then only addresses matching the list will be allowed. This lets
|
|
you easily set up a private game, or a game that only allows players
|
|
from your local network.
