Redirect from 8080 to 80 not working after 6.1 update

[HTR]

I used the web utility to update to 6.1 from 6.0 and followed the instructions in the update.txt file after. The rdir_domain in SQL is set to the correct address.

The IPtables file is:

# Generated by iptables-save v1.4.7 on Tue Oct 12 12:22:57 2010
*mangle
:PREROUTING ACCEPT [0:0]
:INPUT ACCEPT [0:0]

:OUTPUT ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]

:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
COMMIT

Prior to the update, I could use emm.mydomain.com in the browser from any machine on my network and access the initial page. Now I have to use emm.mydomain.com:8080 regardless of how I set the IPtables.

Thanks in advance... Any help is greatly appreciated!!

In case it matters - I'm running Fedora 13

Since this is a firewall and not an OpenEMM issue I recommend to consult a Linux or Fedora forum.
