I would like to modify the iptables on my CentOS 5.8 server so that only specific ips can connect to the machine on a specific port.

Currently, I have the following in my iptables file:

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5000 -j ACCEPT

How would I modify that line if I wanted to allow access for only ips 1.1.1.1 and 1.1.1.2 for instance? (they might not necessarily be sequential ips when I do this for reals).
