The default firewall settings at installation are set to "medium." Try running "redhat-config-securitylevel" and changing it to "none." If that fixes your problem, but you still want a firewall, go back to redhat-config-securitylevel, set it to "high" and open up the specific ports you want to make available in the 'custom' section. If you like, before you do any of this, check the output of 'iptables -L -n'. If it has any rules, then you probably are running firewall rules that are preventing connections.
