Input-all packets destined for the host computer.

Output-All packets originating from host computer

Forward-All packets neither destined for nor Originating from the host computer,but passing through the host computer.This is used if we use the computer as a router.

Delete existing rules-"iptables -F".

Allow only incoming SSH -"iptable A INPUT -i-eth0-p tcp-dport 22 j ACCEPT"

Drop all other incoming packets:

"IPTABLE-A-INPUT-j-DROP".
