LAN IP Address The router's IP address on your Wi-Fi. If you change this address, you’ll have to reconnect your devices to your router. Subnet Mask The router’s subnet mask on your Wi-Fi. It is used to divide a network into subnets so information can be routed correctly to computers and devices.

Wi-Fi > Guest Access Guest Access is a way to share internet access. Guests can get online, but they can’t see or access other connected devices. You can turn guest access on and off, give it a name and password, and set the number of guest devices allowed. When you set up your router, a secure guest network was created automatically on the router's 2.4 GHz/5 GHz band. Guest access is available on these two bands.

Security Security > Firewall The firewall, which protects your Wi-Fi from internet threats, is enabled by default. Security > DMZ The Demilitarized Zone (DMZ) feature can be used to expose a web server, mail server, or web camera to the internet so anyone can access it. This feature is not recommended because it presents significant security risks to the device that you designate for the DMZ. The device will not be protected by the built-in firewalls, internet filters, or modem router web filters.
Security > DDNS The DDNS feature lets you configure a domain name for your home network, which you can use to easily find your network on the internet. This is useful if you want to remotely access a USB drive or web camera over the internet. Select your DDNS service and complete the fields with information provided to you by your DDNS provider.

Security > Port Range Forwarding Port forwarding directs inbound traffic from the internet on range of ports to a specific device on your Wi-Fi.
Security > Port Range Triggering Port range triggering allows the modem router to watch outgoing data for specific port numbers.
