Subject: Iptables rules...
> Hi All,
>
>
> I am new to firewall/iptables can someone help me to clear up some
concepts about firewalling?
>
> If my default rule for the input chain of my external interface is DROP
need I again specify to DROP packets in the INPUT chain of my external
interface?
>
> i.e..
>
> #My Default rule
> iptables -P INPUT DROP
>
> #Drop all attempts on my ext. interface trough port 6000:6063
>
> iptables -A INPUT -i ppp0 -p tcp --dport 6000:6063 -j DROP
>
> If I am right I think that I need not include a rule again saying to drop
packets to my 6000;6063 ports since I do not have a rule saying to accept
connections on these ports...
