You may not control the firewall, but are you able to get any support
for it.  You may want to confirm that the traffic is getting through.

Other than that, you're not getting any hits in the HTTP logs, but
you may still be able to run tcpdump (#tcpdump host IP_address) as a 
network sniffer on the RH box (assuming you only have 1 interface, 
otherwise man tcpdump).

Use Ethereal to view the network packets if it appears tcpdump catches
any traffic.
