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.
