I don't see how NAT translation affects this. I can access the web server from inside or outside the network. Outside using the 64 number, and inside using the 64 or the 192 number. It's making a connection any way I enter it. I guess I don't understand why I can't get the Load Balancer Tester to show that's it's indeed load balancing. Maybe because I'm running it from inside one of the networks that the DNS server is on? And why would this normally be a problem? I mean if I can connect with either the 64 or 192 address from within the network, shouldn't the LB Tester be able to also? > However, it seems to be working now.

Whatever I did to avoid whatever issue your talking about was purely accidental and not by design. :) I think we pretty much just have a one address NAT table. One outside IP to one inside IP.
