iptables configuration issue

Dear list,

I really really need your help to configure iptables to cope with
"connection time out problem" Here what actually the situation is.

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 <myserver>
or nmap -P0 -sT <myserver> ) 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 "connection 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.
