Port Forwarding

The Port Forwarding screen, shown in Figure 7-25, sets up public services on your network, such as web servers, ftp servers, e-mail servers, or other spe- cialized Internet applications. (Specialized Internet applications are any appli- cations that use Internet access to perform functions such as videoconferencing or online gaming. Some Internet applications may not require any forwarding.)

External Port For each application, enter the number of the External Ports (the port numbers seen by users on the Internet) in the appropriate fields.
