DROP input except for 1713
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.
