+
+PACKET FILTERING
+ 
+
+You can add or remove addresses from the filter list with:
+
+addip <ip>
+removeip <ip>
+
+The ip address is specified in dot format, and any unspecified digits will match any value, so you can specify an entire class C network with "addip 192.246.40".
+
+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.
