21.7 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
