When you click the Applications & Gaming tab, you will see the Port Range
Forwarding screen (see Figure 5-17). 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 video-
conferencing 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 designat-
ed PC.
If you need to forward all ports to one PC, click the DMZ tab.
