5.5 Inbound Filters

(Default: No filters). When you use the Virtual Server, Gaming, or Remote
Administration features to open specific ports to traffic from the Internet, you
could be increasing the exposure of your LAN to cyberattacks from the Internet.
In these cases, you can use Inbound Filters to limit that exposure by specifying
the IP addresses of internet hosts that you trust to access your LAN through the
ports that you have opened. You might, for example, only allow access to a
game server on your home LAN from the computers of friends whom you have
invited to play the games on that server.
Inbound Filters can be used for limiting access to a server on your network to a
system or group of systems. Filter rules can be used with Virtual Server, Gaming,
or Remote Administration features. Each filter can be used for several functions;
for example a "Game Clan" filter might allow all of the members of a particular
gaming group to play several different games for which gaming entries have
been created. At the same time an "Admin" filter might only allows systems from
your office network to access the WAN admin pages and an FTP server you use
at home. If you add an IP address to a filter, the change is effected in all of the
places where the filter is used.
