Hi,

 

iīm looking for a script for my adsl conection.

 

i found this

 

iptables -F
iptables -P INPUT DROP
iptables -P OUTPUT DROP
iptables -P FORWARD DROP
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A OUTPUT -p tcp --dport 22 -j ACCEPT
iptables -A OUTPUT -p udp --dport 53 -j ACCEPT
iptables -A OUTPUT -p tcp --dport 53 -j ACCEPT

 

when i apllyed this rules, my machines clients, donīt know acces my machine.

 

but itīs very complex and dificult.
