IP Address seen by Internet Users

Please note that, in the above picture, 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 Dynamic DNS feature to allow
users to connect to your virtual servers by using a URL, instead of an IP address.
To set a virtual server, please open the
Virtual Servers item from the Advanced
Setup - NAT menu.

Forwarded to Internet Host IP Address:

IP addresses can be automatically redirected to local servers configured with private IP addresses. In
other words, depending on the requested service (TCP/UDP port number), the router redirects the
external service request to the appropriate server (located at another internal IP address).
