I dont see how the router can NAT to more than one ip-address. So you need one NAT-router per DSL-line.
I have some experience with the Xincom Twin WAN router. Basically, all it does is NAT RFC1918 address space (by default) and load balance stateless TCP traffic (ie. web traffic) over two outbound links. Established TCP sessions will not fail over, unfortunately, but the device is fairly reliable and does NAT-T fairly easy.
Interesting in that I was talking with a customer about something similar to that today. How can you do nat and failover but keep the existing TCP sessions alive. Given the two upstreams were doing uRPF we couldn't come up with a solution. Rodney
Sure, there's cheaper ways to do this solution without paying for a blackbox, but there's no moving parts in the device and thus is good for small offices that have no clue built-in.
