How to configure port mapping on the EW product?

Port mapping maps the IP address of a device on the LAN to an external network in the form of a combination of a WAN IP address and a port number, so as to provide the external network access service

1.        Scenario 1: When you need to access IP cameras or PCs at home while you are away from home, port mapping needs to be configured.

2.        Scenario 2: When a server needs to be set up in the home network for Internet access, port mapping or demilitarized zone (DMZ) needs to be configured.

3.        Port mapping maps the WAN port IP address of a router to an internal network host and port so that Internet users can proactively access hosts on the LAN.
