[Centos] Messing around with iptables

[scty Library]

Hello all,

Thanks for all your advice I will probably use one of
the distro/products suggested.

I did figure out why it didn't work.  I already had
the RH firewall enabled so that took precedences. 
When I disabled it I was then able to use that command
and it worked just fine.

Thanks again.
