Can this be done? Is this possible with freebsd as the router? Are there better options from cisco et. al.? I searched the -net mail list archives and found a lot about load balancing multiple servers so one didn't get overloaded, but that's not our problem. We want multiple load balanced connections from the internet into the same server/network. Can this be done with separate isp's? or am I asking for trouble? we currently have a single t1 and are looking at a 2.5 mbit DSL line to augment/backup the t1. of course a different provider means a different network range allocated to us. And here is where things get fuzzy for me. What do i tell internic?...ns1 -->network range 1, ns2 -->network range 2 and have the name server hold an IP from each isp's network range?
