Triggering, DMZ and UPnP. Click any of them, and you will be able to configure the corresponding function.
The detailed explanations for each submenu are provided below.
5.7.1 Virtual servers
Virtual servers can be used for setting up public services on your LAN, such as DNS, Email and FTP. A virtual
server is defined as a service port, and all requests from the Internet to this service port will be redirected to
the computer specified by the server IP.
Any PC that was used for a virtual server must have a static or reserved IP Address because its IP Address
may change when using the DHCP function. You can set up virtual servers on this page, shown in figure
5-25:
