From memory, check to see if you have an entry in your /etc/hosts file that actually has your ip address (209.25..) and the correct hostname. Redhat 7.2 Seems to only add a localhost entry to the hosts file and not a proper IP Address / hostname entry.
One that also threw me was the firewall setup in RH7.2 (which set a FW up even though I selected not to run one). The lokkit app also doesn't seem to properly change the FW settings (make a change, exit and then go back in and the settings are the same as they were before the prior change).
