Are you using ipchains for your firewall? It is the default for RH 7x. If so take a look at the output of ipchains -nvL. This will list all the rules inplace with counters that increment each time a rule is used you can look before and after a service ntp restart to see if it is a rule on your box keeping it from getting back to you. I usually turn logging on on my deny/reject rules so I can see what is being stopped. The rules live in /etc/sysconfig/ipchains I believe and adding a -l to the rules of interest will cause an entry into /var/log/messages each time a rule is hit.
