iptables -I INPUT 1 -i lo -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j ACCEPT
iptables -A INPUT -j DROP

8: iptables -N port-scan
This is the beginning of a rule to block furtive port scanning. A furtive port scan is a scan that detects closed ports to deduce open ports. Two more lines are needed to complete this rule:

iptables -A port-scan -p tcp --tcp-flags SYN,ACK,FIN,RST RST -m limit --limit 1/s -j RETURN
iptables -A port-scan -j DROP


Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere anywhere
ACCEPT tcp -- anywhere anywhere tcp dpt:www
ACCEPT tcp -- anywhere anywhere tcp dpt:smtp
ACCEPT tcp -- anywhere anywhere tcp dpt:submission
ACCEPT tcp -- anywhere anywhere tcp dpt:ssmtp

Chain FORWARD (policy ACCEPT)
