passed through the Router from either side of the gateway. The rules are created and
controlled by the network administrator and can be precisely defined. These rules are
used to block access to the LAN from outside the network and/or to deny access to the
WAN from within the network. The Router uses filtering rules to examine data packet
headers for specific information. Packets passing through the Router that do not meet
the criteria specified by the rule set are dropped.
Effective implementation of packet filtering requires detailed knowledge of network
services and communication protocols. An overly complicated filtering scheme can
adversely affect the Router’s performance, while an inadequate set of rules may
needlessly compromise security.
This Router has two fields to configure for filtering which are IP Filters and MAC Filters.
