Hi, I'm trying to set up a PC with two (gig)ether cards as a test system in which a router/firewall/what have you/ could be inserted between the two ether cards. Then I want to send various lumps of test traffic between the two. Unfortunatly Linux is being a little too helpful - whatever the routing tables are set as, any packets intended for one card just hops over internally and doesn't actually go over the wire. Two machines were originally going to be used but due to physical space constraints that has had to be given up. Where is the short-circuit routing done which does this? (I understand it is good and normal behaviour - I just want to turn it off).
