Hello, I did a couple of CentOS (5.0 - 5.1 - 5.2) installations. I vividly, recall a part during the installation that ask the administrator to either enable or disable the internal firewall (IPTables , I can imagine). I always turn this off since the servers are behind a linux firewall anyway.
Have you checked this ?
