Filters, from the Home screen, click Advanced and under Advanced, select Bridge Filters. Figure 15
illustrates a typical Bridge filter configuration.
The User Interface for Bridge Filter allows the user to add/edit/delete, as well as, enables the filter rules. To
add rules, simply define the source MAC address, destination MAC address and frame type with desired
filtering type (i.e. allow/deny), and press the "Add" button. The MAC address must be in 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 "Edit"
select box. The selected filter rule will appear on top section, as with the "Add" filter rule. Make the
desired change to the MAC address, frame type and/or access type, and press "Apply".

deletions are possible. Once all the desired filter rule(s) is/are selected for deletion, press the "Apply"
button. The "Select All" select box can also be used to delete the entire filter rule. It provides a quick
method of selecting all filter rules for deletion.
The "Enable Bridge Filters" button allow the user to enable or disable bridge filtering. It can be 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 ipconfig /all.
The apply button will temporarily save this connection. To make the change permanent you need to click
