you didn't give too many details, so I speculate. If your two routers don't have the same IP set (eg, you're running two DSL lines to two different ISPs), then (1) is your only easy option (unless in your LAN ONLY). For the options below, you need either a specific application profile that lets you do NAT on one of the lines, or you need a common set of IP numbers. I'm not sure that multipath routing gives you failover, "only" load balancing. > 4) ospf, bgp > I am aware of these routing daemons but really don't know too much about > them.

If you can use NAT, you might be able to inject a default route from both routers using OSPF. The client would also talk OSPF and learn both routes from your routers. If you have your own IP numbers (PI space, or you're a LIR), then you can (and usually must) use BGP. Best, --Toni++
