Port Forwarding
Port forwarding (port mapping) is the process of setting a virtual server to establish mapping relations
between: WAN IP address, external port LAN server IP address, and internal port and LAN server IP
addresses. This function allows the WAN user to access services (web, email, FTP, etc.) via the LAN
server. By default, the wireless router will block initiating connection requests from the Internet to
guarantee the security of the LAN. If you want to allow Internet users to access a serve r within the LAN,
set up a virtual server.
