Outbound Rules Example
Outbound rules let you prevent users from using applications such as Instant Messenger, Real
Audio, or other non-essential services.
LAN WAN Outbound Rule: Blocking Instant Messenger
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 on the Schedule screen. You can also have the
firewall log any attempt to use Instant Messenger during that blocked period.
Configuring Other Firewall Features
You can configure attack checks, set session limits, and manage the Application Level Gateway
(ALG) for SIP sessions.
Attack Checks
The Attack Checks screen allows you to specify whether or not the VPN firewall should be
protected against common attacks in the LAN and WAN networks.
