Virtual Servers
This feature, sometimes called Port Forwarding, allows you to make Servers on your LAN
accessible to Internet users. Normally, Internet users would not be able to access a server on
your LAN because:
• Your Server does not have a valid external IP Address.
• Attempts to connect to devices on your LAN are blocked by the firewall in this device.
The "Virtual Server" feature solves these problems and allows Internet users to connect to your
servers, as illustrated below.

using different protocols.
To Internet users, all virtual Servers on your LAN have the same IP Address.
This IP Address is allocated by your ISP.
