Hello listmates, I know this may sound stupid... but I am trying to set up a firewall/filter/forwarder using CentOS 5.5 machine as a platform and I am succeeding but only partially. Fro example, I am literally trying to forward HTTP and HTTPS (TCP 80 and 443) from the public interface to a private IP and TCP 80 works like a charm whereas TCP 443 seems to be a no-go. To that effect: does anyone know of a comprehensive relevant manual? I mean, I must be doing something wrong here though I ain't sure what.
There is nothing CentOS specific about iptables. Just check out http://www.netfilter.org/
Any advice and suggestions much appreciated.
Try the *excellent* fwbuilder application; then you can design your iptables rules graphically and even install them. http://www.fwbuilder.org/
I know I'll never waste time building iptables rulesets by hand again.

Adam, thanks! fwbuilder is indeed a great tool, I can tell.
I didn't mean that iptables was in any way CentOS specific but I did think there could be usage conventions specific to CentOS.
Boris.
