Use Qos And Bandwidth Assignment To Shift The Traffic Mix - NETGEAR ProSafe FVS318N Reference Manual

ProSafe Wireless-N 8-Port Gigabit VPN Firewall FVS318N
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 information about how to enable the DMZ port, see
for IPv4 and IPv6 Traffic
rules, see Configure DMZ WAN Rules
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 have not yet defined. For an example of how to
set up an exposed host, see
Exposed Host on page 159.
VPN and L2TP Tunnels
The wireless VPN firewall supports site-to-site IPSec VPN tunnels, dedicated SSL VPN
tunnels, and L2TP tunnels. Each tunnel requires extensive processing for encryption and
authentication, thereby increasing traffic through the WAN ports.

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 wireless VPN firewall.
Set QoS Priorities
The QoS priority settings determine the quality of service for the traffic passing through the
wireless 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 otherwise would have.
For more information about QoS profiles, see
