To explicitly send things through a specific interface, you need to use some magic, like PF_RAW. ping for example is one program that will do this (-I option). > Did you check that the two destination ips have routes through different > interfaces, and not go out through the same one? One cannot have the same subnet on multiple interfaces, because ARP queries will only be sent through the first one. You need br0 (or bond0 - depending on how you plan to plan your network) to make them one interface.
