+
+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 you can use '*' to 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.
+
+TTimo NOTE: for persistence, bans are stored in g_banIPs cvar MAX_CVAR_VALUE_STRING
+The size of the cvar string buffer is limiting the banning to around 20 masks
+this could be improved by putting some g_banIPs2 g_banIps3 etc. maybe
+still, you should rely on PB for banning instead
