Port Range Forwarding
When you click the Applications & Gaming tab, you will see the Port Range Forwarding screen (see Figure 7-18).
Port Range Forwarding sets up public services on your network, such as web servers, ftp servers, e-mail servers,
or other specialized Internet applications. (Specialized Internet applications are any applications that use Internet
access to perform functions such as videoconferencing or online gaming. Some Internet applications may not
require any forwarding.) When users send this type of request to your network via the Internet, the Router will
forward those requests to the appropriate PC.
Before using Forwarding, you should assign a static IP address to the designated PC.
If you need to forward all ports to one PC, click the DMZ tab.
