The above iptables
I've got a server with several ip's on eth0. I want to block all traffic
*except* to port 80 on them, but not on any other IPs, so that
eth0 is www.xxx.yyy.zzz
eth0:1 is www.xxx.yyy.ggg
eth0:2 is www.xxx.yyy.hhh
I've tried
-A RH-Firewall-1-INPUT -p tcp -d www.xxx.yyy.ggg --dport ! 80 -j DROP
-A
However, I can telnet to www.xxx.yyy.hhh 443. What's wrong with the rules?
from other machine? from localhost ?

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 want to drop *anything* other than to port 80.

Can't you set up a default rule of drop, and then allow port 80?

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.

reference a chain, you need to use -N (for new) instead of -A (for
append).
