25.7 Security Policy Example Applications
Suppose you decide to block LAN users from using IRC (Internet Relay Chat) through the Internet. To do
this, you would configure a LAN to WAN Security Policy that blocks IRC traffic from any source IP address
from going to any destination address. You do not need to specify a schedule since you need the
Security Policy to always be in effect. The following figure shows the results of this policy.
