rules, see 
Exposed Hosts
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 did not yet define. For an example of how to set 
up an exposed host, see 
VPN and L2TP Tunnels
The VPN firewall supports site-to-site IPSec VPN tunnels, and L2TP tunnels. Each tunnel 
requires extensive processing for encryption and authentication, thereby increasing traffic 
through the WAN ports. For information about IPSec VPN and L2TP tunnels, see 
.
Use QoS and Bandwidth Assignment to Shift the Traffic Mix
By setting the QoS priority and assigning bandwidth profiles to firewall rules, you can shift the 
traffic mix to aim for optimum performance of the VPN firewall.
Set QoS Priorities
The QoS priority settings determine the Quality of Service for the traffic passing through the 
VPN firewall. You can assign a QoS priority to LAN WAN and DMZ WAN outbound firewall 
rules. The QoS is set individually for each firewall rule. 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 
priority.
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 would otherwise be assigned.
For more information about QoS profiles, see 
Assign Bandwidth Profiles
When you set the QoS priority, the WAN bandwidth does not change. You change the WAN 
bandwidth that is assigned to a service or application by applying a bandwidth profile to a 
LAN WAN inbound or outbound rule. The purpose of bandwidth profiles is to provide a 
method for allocating and limiting traffic, thus allocating LAN users sufficient bandwidth while 
preventing them from consuming all the bandwidth on your WAN links. For more information 
about bandwidth profiles, see
