I mentioned in a previous post that I had, for a time, both DSL and cable internet; but I didn't go into detail about how had my router hooked up to both lines, routing traffic over them concurrently. It's time to rectify that omission. Although this multihomed configuration did not last long, I'm still using pretty much the same tools/config to take advantage of the multiple IP addresses I've managed to snag from my ISP.

This is how I've setup my Linux 2.6-based router using 'ip route', 'ip rule' and iptables to get WAN-bound traffic coming from the local subnets to exit one of several WAN links depending on different criteria; mostly source IP.
