    Can anyone help me iptables solution for the follwing specification.
    I want to drop all packets coming to my host , except for port 1713 .

    It doesn't work :
    iptables -A INPUT -i eth0 -J DROP
    iptables -A INPUT -p tcp --dport 1713 -j ACCEPT

    You have to put the second rule first:

    iptables -A INPUT -p tcp --dport 1713 -j ACCEPT
    ptables -A INPUT -i eth0 -J DROP

    It is a matter of priority. Otherwise everything will be dropped.
