Perhaps I am mixing up two separate networking concepts. On a machine configured to act as a gateway, I would expect a single interface with more than one subnet to route packets correctly across those subnets. That may not be how it works in practice. If it does not work, I would question why not. If it does work then I would expect the same behaviour on each of a bridge's constituent interfaces? -- Jay L. T. Cornwall http://www.jcornwall.me.uk/
