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 Virtual Servers using a URL, instead of an
IP Address.
Virtual Servers Screen
The "Virtual Servers" feature allows Internet Users to access
PCs on your LAN.
The PCs must be running the appropriate Server Software.
For Internet Users, ALL of your Servers have the same IP
address. This IP address is allocated by your ISP.
To make it easier for Internet users to connect to your Servers,
you can use the "DDNS" feature. This allows Internet users to
connect to your Servers with a URL, rather than an IP address.
This technology works even if your ISP allocates dynamic IP
addresses (IP address is allocated upon connection, so it may
change each time you connect).
