I don't think anyone has pointed out the following advantage of an IP gateway over a level 2 bridge between physical Ethernets. Ethernet broadcasts are filtered by IP gateways whereas in the case of bridges, full IP functionality between gateways requires that all Ethernets so joined see the combined broadcasts of each network in the group. -------
