how could i add / remove iptable rules on cet os 5.4 final for tcp / udp
base on ports
If you don't want to mess with iptables, take a look at the firewall
configuration tool system-config-securitylevel-tui. I think there's a
graphical app also, but I've never used it. If you only need to
open/close ports on a tcp/udp basis, this tool will do the job.
Right now looking for an example. In my own documentation, I have some
screenshots of the tool. Here, for example (second screenshot), opening
port 67 for UDP requests :

Or here (first screenshot), opening port 53 for both TCP and UDP requests :
http://www.microlinux.fr/doc_en_stock/dns.html
If you want more complicated stuff, you'll have to dive into iptables,
though.
Cheers,
Niki
