I'm new to setting up servers and when I'm trying to follow a guide for doing iptables. The guide says to use RH-Firewall-1-INPUT while i see the original configuration just using INPUT. I'm wondering what are the differences between these?

Can you post the full set of rules or a link to the guide? –  Zoredache Feb 24 '12 at 4:53
The guide that I am talking about is here cyberciti.biz/faq/howto-rhel-linux-open-port-using-iptables. And the particular entry that I am talking about is about opening port 80. Thanks. –  gtr32x Feb 24 '12 at 6:19

Starting with RH/CentOS 6, the RH-Firewall chain is removed. Now just use the default INPUT chain.

Thanks for the answer! Just wondering though, if you can tell me a quick explanation of the purpose of it, or point me to a simple guide that explains it. I've looked around on the net and just couldn't find an adequate resource. Thanks! –  gtr32x Feb 24 '12 at 7:06
the wikipedia article for iptables explains chains of rules and includes a diagram link –  evan Feb 24 '12 at 9:06
