This is the file I made for trying out purposes. It's actually allow DNS, telnet and ftp services only and disallow other then those services. # Allow ftp and ftp-data pass in proto tcp from any to any port = 20 keep state pass out proto tcp from any to any port = 20 keep state pass in proto tcp from any to any port = 21 keep state pass out proto tcp from any to any port = 21 keep state # Allow telnet pass in proto tcp from any to any port = 23 keep state pass out proto tcp from any to any port = 23 keep state # Allow DNS pass in proto tcp from any to any port = 53 keep state pass out proto tcp from any to any port = 53 keep state Please point me out if there's anything wrong with this. Thanx in advance. regards, ****************************************************************** MUHAMMAD NAJIB ABDUL MUKTHI member of My-Linux.ORG NETWORK ENGINEER / SYSTEM ADMINISTRATOR http://www.my-linux.org Cutting Edge Enterprise MPKS Tower Jalan Tunku Ibrahim najib@mrsm.org 05000 Kedah Darulaman. najib@csi-x.net http://najib.csi-x.net najib@kdupg.edu.my Tel : 012-4717452 najib@my-linux.org ****************************************************************** To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
