This feature is available only if you are using the Internet Sharing Device for
shared Internet access, rather than for LAN-to-LAN connection.
The Virtual Servers feature allows Internet users to access
standard Servers on your LAN, via the Internet Sharing Device.
Normally, Internet users would not be able to access a server on your LAN because:
The "Virtual Server" feature solves these problems and allows Internet users to connect to your servers. However, your LAN must have an existing connection to the Internet. Internet users cannot open a connection.
Virtual Server operation is illustrated below.
Note
that, in this illustration, both Internet users are connecting to the same IP
Address, but using different protocols.
To Internet users, all virtual Servers on your LAN have the same IP
Address.
This IP Address is the IP Address allocated by ISP on the Internet Account
screen, for the port which you are using.
This address should be static, rather than dynamic, to make it easier
for Internet users to connect to your Servers.
The Internet Gateway supports two (2) types of Virtual Servers:
Note that the TOTAL number of Virtual Servers which can be used is 10.

Once
configured, anyone on the Internet can connect to your Virtual Servers.
For the destination address, they
must enter the IP Address shown in the IP Address allocated by ISP on the
Internet Account screen for the port you are using. This address
should be static (fixed) to make connection easier.
e.g.
It is possible to configure the Internet Gateway itself as a Virtual Web
Server. Once this is done, you can configure this device through the Internet.
For the remote PC, the destination IP Address is the IP Address allocated by ISP
shown on the Internet Account screen, for the port you are using.
Upon connecting to the Internet Gateway, you will be prompted for the
device password. You should set a password!
