You lost me here already. The gateway for a given IP has to be on the same subnet as the given IP. ie, if IP 192.168.1.254 has gateway IP 192.168.1.1, IP 192.168.2.254 can't use 192.168.1.254 as it's gateway also because it would have to leave the subnet, thereby going thru the gateway, just to get to the gateway... which obviously doesn't make any sense. Could you explain this a bit more? >I tried using > alias'd IP's but just ran into serious problems (I'm assuming because > the cable co's router didn't like me trying to use multiple IP's with > the same MAC address).
