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.
|
|
|
|
g_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.
