Hi,

I am using my RH9.0 Linux box as my server and firewall, and want these
ports to be opened:
21, 22, 25, 80, 110 for external;
samba(139), mySQL(3306) for internal.

But now, I found those ports below had opened:

21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
80/tcp open http
110/tcp open pop-3
111/tcp open sunrpc
139/tcp open netbios-ssn
143/tcp open imap2
443/tcp open https
3306/tcp open mysql

How can I specify them respectively for internal and external? Thanks for
any idea.
