I think it is the starting point I'm after, but there's still one thing concerning me. As I can see it, this article discusses the idea of load balancing traffic routing over two interfaces in separate networks - essentially the device doing the load balancing would have 3+ interfaces, each on their own net/subnet. This, of course, is relatively easy to setup on most routers worth their salt. What I'm thinking of, however, is the ability to direct traffic to different routers. So, rather than the load balancing device having 3+ interfaces on their own net/subnets, it would have 1 interface on the same net/subnet as two different routers (ie all devices in 192.168.1.0/24) ie: Router 1 = 192.168.1.1/24 Router 2 = 192.168.1.254/24 eth0 = 192.168.1.2/24 Of course I could add 2 subinterfaces (eth0.1 and eth0.2) with addresses in different nets/subnets and modify the routers to have corresponding IP addresses, but that then essentially turns the proxy machine into a router.
