Clean all rules:
iptables -F
iptables -X
Use these default parameters:
iptables -P INPUT DROP
iptables -P OUTPUT DROP
iptables -P FORWARD ACCEPT
Then do the following:
iptables-save > /etc/network/iptables
iptables-restore < /etc/network/iptables
Then enter:
iptables -A INPUT -p tcp -m tcp -dport 80 -j TARPIT
Or you can set a trap for ALL ports, except for your own:
iptables -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport 25 -j ACCEPT
iptables -A INPUT -p tcp -m tcp -j TARPIT
