what is a wan port

A WAN port is a port on a router that connects to your modem by an Ethernet cable. WAN stands for Wide Area Network, which is basically the internet. The WAN port is used to connect the router to your internet connection, which is built up by your ISP-supplied modem. The WAN port is usually labeled "Internet" or "WAN" and is separated from the LAN ports with a firewall. The LAN ports are used to connect local network devices to your home network. The WAN and LAN ports look the same, and may even be placed next to each other, but they are internally separated. The WAN port is used to establish a connection with an external network like the internet, while the LAN port is used to connect computers and other client machines within a limited area, such as an office.
