Enabling Port Forwarding to Allow Access to Services
By default, the Router’s firewall prevents access from the Internet to your private
network. You can use the Port Forwarding screen to allow public access from the
Internet to your network resources, 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.
