Help - Virtual Servers

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).
