MAC Bridging
Configuration – Network> Interfaces> MAC Bridging
The Ethernet MAC bridge function will create 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
Enable 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. E.g.
“00042d” will allow all Ethernet packets with a source MAC address starting with
“00:04:2d”.

Spanning Tree Protocols
Configuration – Network> Interfaces > Ethernet > Spanning Tree Protocols
The Rapid Spanning Tree Protocol (RSTP) is a layer 2 protocol which ensures a loop free
topology on a switched or bridged LAN whilst allowing redundant physical links between
switches. When enabled, the TransPort device will use RSTP but this is backwards
compatible with STP.
