This doesn't make sense. Before we go farther into this, I need to get this
straight. I need to know the topology (cabling) not just the IP#s. Both the
server and the firewall have a public and private IP# each, so...how are
they cabled together? Side-by-side? Back-to-back?....Now back-to-back
couldn't possibly work but I need to verify how it is rigged up, I can't
just assume someone did it one way or the other,...you'd be surprised what
people do sometimes.

Side-by-Side:

                ----- Server----->
              / \
LAN--- Hub?-----> Router--->Internet
              \ /
                ---- Firewall---->

Back-to-Back:

LAN--->Server---> Firewall --->Hub?-->Router--->Internet
