correct way to set timezone & clock/date?

[Steven A. DuChene]

Hmm, I have added these systems to the ntp.conf file on my external gateway system
that serves as a firewall for my network but when I try to start the ntp service it sits
there forever trying to get an initial date and time from those systems.

This external system has iptables rules and the ones that have to do with udp port 123
are the following:

-A input_ext -p udp -m pkttype --pkt-type broadcast -m udp --dport 123 -j ACCEPT 
-A input_ext -p udp -m udp --dport 123 -j ACCEPT 

I am assuming I must have some sort of firewall issue blocking the acquisition of
the date and time from the external servers but it would seem like the above rules
that were already present in my firewall setup would have made that a non-issue.

Anyone got any ideas or suggestions about this?
