nmap show filtered

[crossfire]

Hi!

I would like to know if is normal when u disable services like httpd (anyone), and u do rules in iptables for drop packets like this one:

iptables -A -p tcp --dport 80 -j DROP

Is it normal when u run
#nmap IP u see 80/http filtered? Should be to appear none in the results of nmap?

that sounds fine to me
AFAIK iptables works like this
LAN - eth0 - iptables - box

so even though you allowed traffic over that port it still passes through iptables and is therefore filtered
