How to make iptables to allow only certain IP's addresses

How do config iptables to allow only certain IP's addresses

What is it you are looking for? Are you looking to allow only certain ip addresses to access certain ports or services?

For example to allow ip's in the range of 192.168.1.100-192.168.1.200 to access ssh port 22,

iptables -A INPUT -p tcp --destination-port 22 -m iprange --src-range 192.168.1.100-192.168.1.200 -j ACCEPT

Here is a nice how-to for a start..
