I am using the lastest redhat 5.4. When I look at my iptables -L I have a short firewall and it does not let much in. If I do an Nmap, I get more ports than the firewall allows.
If I want to see what I really have for a firewall, I can test ALL Ports individually or is there some way to do this easly ? I thought that if I blocked a port in iptables, it would not show up in nmap.
Oh, keep an eye on my user id today, I will be asking a bunch of silly questoins that are easy pickings for the right person :) Today is a "study iptables" day :)
