That would be a Protocol Gateway, but my be known by other names depending
on who's book you read. A Bridge is nothing more than a device that
switches packets at Layer2 (MAC address). Most have the same network
technology on both sides.
The most common Bridge found on a LAN now days is a simple Switch.
The second most common would be a router on a WAN link where the same Layer4
Network exists on both sides and the router is configured to "bridge"
according to Layer2 rather than route according to Layer3. We used to run
several of those here, now we are down to just one. It runs from our main
building to an office across from the Governor's Office in the State Capitol
over a 30 mile distance.
