ProSecure Unified Threat Management (UTM) Appliance

WARNING:

For security, NETGEAR strongly recommends that you avoid creating an exposed host. When a computer is designated as the exposed host, it loses much of the protection of the firewall and is exposed to many exploits from the Internet. If compromised, the computer can be used to attack your network.

Outbound Rule Example

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

LAN WAN Outbound Rule: Block Instant Messenger

If you want to block Instant Messenger usage by employees during working hours, you can create an outbound rule to block such an application from any internal IP address to any external address according to the schedule that you have created in the Schedule screen. See an example in the following figure.

You can also enable the UTM to log any attempt to use Instant Messenger during the blocked period.
