I have a couple CentOS boxes running in our DMZ and although they are running behind a firewall, I'm also running iptables. One thing I cannot do it yum update. What ports are required for this? I have outbound http open and I can browse to sites using firefox.

If I run an ethereal scan the process seems to stop with DNS queries, but I can resolve mirrorlist.centos.org without a problem. Anyone know what the problem could be?

If I stop iptables everything works of course.

I depends on the server, but either outbound to port 80 or outbound to port 21 (for ftp).
