Port Forwarding

This feature, sometimes called

Virtual Servers

, 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 "Port Forwarding" feature solves these problems and allows Internet users to connect to
your servers, as illustrated below.

Figure 20: Port Forwarding

IP Address seen by Internet Users

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 allocated by your ISP.

This address should be static, rather than dynamic, to make it easier for Internet users to
connect to your Servers.

However, you can use the

DDNS (Dynamic DNS)

feature to allow users to connect to your

Port Forwarding using a URL, instead of an IP Address.
