A single rule doesn't tell us enough. Dump the entire firewall to a

Maybe, I am not understanding you, but if you just want port 80 to be
available on each of those machines, all you needs is to have this in your
iptables:
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j
ACCEPT

I've got a server with several ip's on eth0. I want to block all traffic

eth0 is www.xxx.yyy.zzz

Hello,
When you're entering the rules from the CLI, the first time you
reference a chain, you need to use -N (for "new") instead of -A (for
"append"
Thank you
Can I know how to define the "SSH_CHECK"
and white list?
I only know to use iptables -A
Thank you

Hi,
Below is an example that I use to limit the rate of new connections to a
particular port/service. You should be able to mold this to work with
whatever service you would like to protect.
