11 NAT forwarding
11.1 Virtual server
11.1.1 Overview
By default, internet users cannot actively access the LAN of the router.
The virtual server function opens a port of the router, and binds the LAN server to the port using
the server’s IP address and intranet service port. All access requests to the WAN port of the router
will be directed to the server. Therefore, the server within the LAN can be accessed by internet
users and the LAN can be free from attacks from the internet.
For example, the virtual server function enables internet users to access web servers or FTP
servers within the LAN.
To access the page, log in to the web UI of the router, and navigate to NAT Forwarding > Virtual
Server.
