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.
