a xx-xx-xx-xx-xx-xx format, with 00-00-00-00-00-00 as “don’t care”. Blanks can be used in the MAC
address space, and would be considered also as “don’t care”.
To edit/modify an existing filter rule, select the desired rule created previously from “Add” in the

set/unset during any add/edit/delete operation. It can also be set/unset independently by just pressing
the “Apply” button.

Note: The bridge filter table contains 3 hidden rules. These rules are entered automatically by the
system to ensure the user does not "lock" them out of the system. The first rule allows any and all
ARP frames through the system. The second rule allows all IPv4 frames with the destination MAC
address of the bridge to go through. The third rule allows all IPv4 frames with the source MAC
address of the bridge to go through.
Note: On a windows based machine, to find a MAC address, ad a dos prompt type
