I have configured iptables to drop nmap and other port scanning techniques ( collected from internet, like XMAS scan, FIN scan etc...). If I run nmap against the server ( like nmap -P0 or nmap -P0 -sT ) then the firewall successfully dropping the scan packets and make the nmap scan to wait for *looooong* . Good. But on the other hand the http and mail server running on the server providing "time out error" hence it is not possible to connect the mail /apache and other services running on that server during port scanning against it. Could any one kindly suggest how to cope with this situiation ? Thanks for your time.
