Hi,
so if a request is made to the public interface of my firewall is
the request processed as the public IP or the private IP for the firewall.
example :
I want to block telnet access to my firewall from the internet. I write
rules
in the INPUT chain to do this.Would i write the rule blocking telnet using
the public or private interface
/sbin/iptables -A INPUT -i eth0 -d 10.0.0.1 -p tcp --dport 23 -j DROP
or
/sbin/iptables -A INPUT -i eth0 -d $MY_PUB_IP -p tcp --dport 23 -j DROP
Thanks
jd
