10.5 Access Control (Rules)

An Access Control List (ACL) rule is a manually-defined rule that can accept, reject, or drop incoming or
outgoing packets from your network based on the type of service. For example, you could block users
using Instant Messaging in your network. This screen displays a list of the configured incoming or
outgoing filtering rules. Note the order in which the rules are listed. Click Security > Firewall > Access
Control to display the following screen.
Note: The ordering of your rules is very important as rules are applied in turn.
