LAN port) can be dedicated as a hardware DMZ port to safely provide services to the Internet 
without compromising security on your LAN. By default, the DMZ port and both inbound and 
outbound DMZ traffic are disabled. Enabling the DMZ port and allowing traffic to and from the 
DMZ increases the traffic through the WAN ports.

For the information on how to enable the DMZ port, see 

. For the procedures on how to configure DMZ traffic rules, see 

.

Specifying an exposed host allows you to set up a computer or server that is available to anyone on 
the Internet for services that you have not yet defined. For an example on how to set up an exposed 
host, see 

The UTM supports up to 25 site-to-site IPsec VPN tunnels and up to 13 dedicated SSL VPN 
tunnels. Each tunnel requires extensive processing for encryption and authentication, thereby 
increasing traffic through the WAN ports.

For information about IPsec VPN tunnels, see 

.” For information about SSL VPN tunnels, see 

By specifying QoS and bandwidth profiles and assigning these profiles to outbound and inbound 
firewall rules, you can shift the traffic mix to aim for optimum performance of the UTM.

The QoS profile settings determine the priority and, in turn, the quality of service for the traffic 
passing through the UTM. After you have created a QoS profile, you can assign the QoS profile to 
firewall rules. The QoS is set individually for each service. You can change the mix of traffic 
through the WAN ports by granting some services a higher priority than others:

•

You can accept the default priority defined by the service itself by not changing its QoS 
setting.

•

You can change the priority to a higher or lower value than its default setting to give the 
service higher or lower priority than it otherwise would have.
