You don't. That's what a router does. If you want to move data between two different networks you either need a router, or you need to cheat (like you currently are) and just ignore the arp messages. You can just turn on forwarding on the BSD machine with the two NICs and it will act as a router for you. -- Bill Moran Potential Technologies http://www.potentialtech.com
