For the system to be a router, the interfaces MUST be on different networks--that's what defines a "router" in the first place (it routes packets between networks). If the NICs are on the same network, you simply have a machine with two different network addresses (which is better handled by one NIC with aliases on it...eth0, eth0:0, eth0:1, etc.). ---------------------------------------------------------------------- - Rick Stevens, Senior Systems Engineer rstevens@xxxxxxxxxxxxxxx - - VitalStream, Inc. http://www.vitalstream.com - - - - Whoever said "Money can't buy friends" obviously never brought - - donuts to the office. - ----------------------------------------------------------------------
