IP Address Seen by Internet Users
To Internet users, all virtual servers on the LAN have the same IP address. This IP address is allocated by the ISP.
This address should be static, rather than dynamic, to make it easier for Internet users to connect. If desired, use the DDNS (Dynamic DNS) feature to allow users to connect to Port Forwarding using a URL instead of an IP address.
