routing tables, multiple NICs...
 

Need help determining what NIC has default traffic coming in/going out. Example, looking at a machine that has a public IP on eth0 and a private IP on eth1, by looking at the routing table I need to know what traffic arrives/departs on what NIC.

Any suggestions on where to look would be greatly appreciated.
