Hi, Given the following two variations of the same setup: HostA ------------------ HostB eth0: eth0: 1.1.1.1/24 1.1.1.2/24 2.2.2.1/24 2.2.2.2/24 and: HostA HostB eth0:1.1.1.1/24 ------------ eth0:1.1.1.2/24 eth1:2.2.2.1/24 ------------ eth1:2.2.2.2/24 (basically same setup but with two NICs on each host) How does one set up advanced routing so that when HostA sends a packet from 1.1.1.1 to 2.2.2.1, it goes via HostB, and vice versa: a packet from 2.2.2.1 to 1.1.1.1 also goes via HostB. This setup would allow me to do traffic-generator/ troughput-like tests when HostB is a low-end machine. I have been fiddling around with ip route/ip rule, but the biggest problem I seem te be having is that when I change/delete an entry from the local table, HostA no longer replies to ARP queries on the wire.
