MAC Bridging
The Ethernet MAC bridge function creates an Ethernet bridge between two physically separate
Ethernet networks. It is possible to allow bridging over DSL, W-Wan, ISDN and PSTN connections
but note that the only restriction on the traffic sent across the link is done via MAC address
filtering and that all Ethernet traffic will be bridged, no firewall restrictions are applied to this
traffic.
Once the bridge has been configured, the MAC addresses to bridge need to be configured in the
MAC bridge table.
Enable
Enables MAC bridging on the Ethernet interface.
Forward to IP address
The IP address of the remote router to which the Ethernet packets will be bridged to.
Port
The TCP port that the remote router is listening on.
Listen on Port
The TCP port that the router will listen on for incoming bridged packet from the remote
router.
MAC Address
The Ethernet destination MAC address of packets to be bridged. It is possible to allow a range
of MAC addresses by configuring only the significant part of the MAC address. such as 00042d
will allow all Ethernet packets with a source MAC address starting with 00:04:2d.
