Virtual Server Enable or disable Virtual Server. Virtual servers can be used for setting up
public services on your local area network, 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 LAN server. Virtual Server
function not only makes the users from internet visit the local area network,
but also keeps network security within the intranet as other services are
still invisible from internet. The LAN server must have a static or reserved
IP Address because its IP Address may change when using the DHCP
function.
To configure Virtual Server:
Click Add , specify the following parameters and Enable the entry. Click
Save .
Enter the IP Address of the PC providing the service application.
Enter the Internal Port number of the PC running the service
application. You can leave it blank if the Internal Port is the same as the
Service Port, or enter a specific port number.
Enter the numbers of external Service Port. You can type a
service port or a range of service ports (the format is XXX – YYY, XXX is the
start port, YYY is the end port). Internet users send request to the port for
services.

UDP, or TCP/UDP.
