Virtual Server
Virtual Server allows you to enable users to access the Internet, FTP and other services from

addresses, they will be routed to the server at the internal LAN end as appropriate in accordance
with externally required services.
WAN Port Range: Input the port rang for the WAN side.
TCP/UDP: Select the communication protocols used by the server, TCP, UDP or Both.
LAN Host IP Address: Enter the IP address that provides various services.

Either this function or virtual server can be selected for use in accessing external services.
NOTE: Only one host in the LAN can be set as a DMZ host.
