VPN Tunnels
The wireless firewall permits up to 50 VPN tunnels at a time. Each tunnel requires extensive
processing for encryption and authentication.
See
Chapter 5, “Virtual Private Networking
” for the procedure on how to use this feature.
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 ports by granting some services a higher priority than
others. The quality of a service is impacted by its QoS setting, however.
See
“Setting Quality of Service (QoS) Priorities” on page 4-18
for the procedure on how to use
this feature.
Tools for Traffic Management
The ProSafe Wireless ADSL Modem VPN Firewall Router includes several tools that can be used
to monitor the traffic conditions of the firewall and control who has access to the Internet and the
types of traffic they are allowed to have. See
“Monitoring” on page 6-12
for a discussion of the
tools.
Administrator and Guest Access Authorization
You can change the administrator and guest passwords, administrator login time-out, and enable
remote management. Administrator access is read/write and guest access is read-only.
