ProSafe VPN Firewall 200 FVX538 Reference Manual
•The remote system receives the PCs request and responds using the different port numbers that you have now opened.
•This Router 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

DMZ Port
The DMZ Port allows you to set up the DMZ port. Specifying a Default DMZ Server allows you to set up a computer or server that is available to anyone on the Internet for services that you haven't defined.
The default setting of the rules is that the DMZ port and both inbound and outbound traffic is disabled. Enabling the DMZ port increases the traffic through the WAN ports.
The VPN firewall makes LAN port 8 a dedicated hardware DMZ port when DMZ is enabled (see “Router Front Panel” on page
See “Configuring and Enabling the DMZ Port” on page
VPN Tunnels
The VPN firewall permits up to 200 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.
