A bridge basically allows all traffic from one network to another. People with a cable modem from saturn (or whoever they are now) have basically a bridge to the internet, through which everything may pass (which is why you need a firewall machine (which acts as a router for the rest of the lan) when using one. A router is more choosy - eg those with a jetstream connection using a router (like the nokia m1122 etc) only see their own traffic on the LAN side of the connection. So, you are not bridging these networks, so forget my earlier answer :-) -- Nick Rout <[EMAIL PROTECTED]>
