There are filter tables available for both the Ethernet connection and WAN link. Whilst it is preferable to block packets prior to forwarding them to the WAN link, it may arise that control of the remote site is not possible, and therefore WAN filters must be used to protect from unwanted incoming traffic.

Filters are referenced for receive traffic only i.e. all IP packets from the Ethernet will be referenced through the Ethernet IP filter before forwarding to the internal routing tables. If the user configures both Ethernet and WAN filters they should be a mirror image of one another, except for the swapped IP source/destination Address and Port numbers.

in 2x6, 4x3 or 12x1 format.

DELETE

Filtering tables will run from RAM
