Thanx Darren,
Let me try this here. 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,
