Hi all,
I use iptables as a firewall on my local machine to filter any incoming
connections one some ports I want to protect. I have tested this with one
single port and then run a portscan o that machine. nmap was not able to
connect to that protected port but it marked the port as "filtered". How can
I prevent this? nmap should not be able to see if and which ports are
filtered. I have tried with DENY and REJECT but got the same report.
Thanx
Michael
