I've never looked into some of the open-source load balancing solutions, but I know they exist are are out there. The F5's I mentioned are probably around $20k each, and you need two obviously, so if you're on a limited budget those are not the solution for you. I'd google for open source load balancer. I know OpenBSD has some failover capacity through something called CARP, but I'm not sure how that would work with your solution. Nate Tobik (412)661-5700 x206 VigilantMinds ..... Thanks for the reply, Nathan - Are there any such interfaces that are software-based? I think that Jasper's suggestion would be the most feasable, but I'd still like to know my options. In my mind, hardware immediately equates to $$$, whereas software immediately does not.
