6.9 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.
