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.
Advanced > Filters > IP Filters
This window will aid the use in configuring filters for IP addresses. This will deny specified LAN IP addresses or specific ports associated with these LAN IP address from accessing the Internet. Well known ports have already been previously set in the IP Filters List and can be modified by clicking their corresponding edit icon, and simple adding an IP address to the configuration.
To access this screen, click the Advanced tab along the top of the configuration window and then the Filters tab to the left hand side.
