Packet filters are used to set firewall rules which define what type of data traffic is allowed across the
RouteFinder's firewall. There are certain System Defined Rules that exist by default. In addition, you can
specify whether particular packets are to be forwarded through the RouteFinder system or filtered. These
rules are set with the help of network/host and service definitions that have already been set up in the
Networks
section.
