Introduction

A bridge works like a transparent switch/hub between two or more interfaces and clients on any of the bridged interfaces can communicate with each other exactly as if they were part of the same network. For bridging two interfaces in two geographically separate locations over a tunnel see the article on EtherIP.

Example

Below is a complete example in plain-text for bridging two local interfaces with each other and clients on either side of the bridge sharing the same DHCP Server and firewall rules. This can of course be performed using the graphical web administration, as well. Pay particular attention to the fact that the vr2 interface does not have any IP address assigned to it.
