Firewall Protection and Content Filtering

v1.0, November 2007

Outbound Rules Example

Outbound rules let you prevent users from using applications such as Instant Messenger, Real
Audio or other non-essential sites.

LAN WAN Outbound Rule: Blocking Instant Messenger

If you want to block Instant Messenger usage by employees during working hours, you can create
an outbound rule to block that application from any internal IP address to any external address
according to the schedule that you have created in the Schedule menu. You can also have the
firewall log any attempt to use Instant Messenger during that blocked period.

Figure 4-12

1. Select Any and Allow Always (or Allow by Schedule)

2. Place rule below all other inbound rules
