Using Qos To Shift The Traffic Mix - NETGEAR SRXN3205 - ProSafe Wireless-N VPN Firewall Wireless Router Reference Manual

• The remote system receives the PCs request and responds using the different port numbers that
you have now opened.
• This firewall matches the response to the previous request and forwards the response to the
PC. Without port triggering, this response would be treated as a new connection request rather
than a response. As such, it would be handled in accordance with the Port Forwarding rules.
– Only one PC can use a port triggering application at any time.
– After a PC has finished using a port triggering application, there is a time-out period
before the application can be used by another PC. This is required because the firewall
cannot be sure when the application has terminated.
See "Enabling Port Triggering" on page 5-23
VPN Tunnels
The VPN firewall permits up to 5 IPsec VPN tunnels and 3 SSL VPN tunnels not to exceed 8 total
tunnels at a time. Each tunnel requires extensive processing for encryption and authentication.
See Chapter 6, "Virtual Private Networking Using
VPN, and Chapter 7, "Virtual Private Networking Using SSL
SSL VPN.

Using QoS to Shift the Traffic Mix

The QoS priority settings determine the priority and, in turn, the quality of service for the traffic
passing through the firewall. The QoS is set individually for each service.
• 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.
The QoS priority settings conform to the IEEE 802.1D-1998 (formerly 802.1p) standard for class
of service tag.
You will not change the WAN bandwidth used by changing any QoS priority settings. But you will
change the mix of traffic through the WAN port by granting some services a higher priority than
others. The quality of a service is impacted by its QoS setting, however.
