# Networking

- [Firewall](https://how.router.works/net/firewall.md): The router firewall controls the forward packet streams from incoming network interfaces to outgoing network interfaces.
- [Port Forward](https://how.router.works/net/firewall/port-forward.md)
- [WiFi Hotspot](https://how.router.works/net/wifi.md)
- [WiFi Relay](https://how.router.works/net/wifi/relay.md): A WiFi relay, also known as a WiFi repeater or WiFi extender, is a feature that allows a router to connect to an existing WiFi network and rebroadcast the signal to extend the coverage range.
- [Guest WiFi](https://how.router.works/net/wifi/guest-wifi.md): Enabling a guest WiFi hotspot to provide internet access to guests and add a security layer by keeping guest devices separate from the master network.
- [Parent Control](https://how.router.works/net/wifi/parent-control.md)
- [Traffic Control](https://how.router.works/net/traffic.md)
- [IP and DNS](https://how.router.works/net/traffic/ip-dns.md)
- [SQM QoS](https://how.router.works/net/traffic/sqm-qos.md): With SQM traffic control, you can enable traffic shaping, better mixing (Fair Queueing), active queue length management (AQM), and prioritization on one network interface.
- [Load Balancing](https://how.router.works/net/traffic/load-balancing.md): A dynamic and flexible mechanism to distribute network traffic across multiple internet connections.
- [Intranet Routes](https://how.router.works/net/traffic/intranet-routes.md): Manually configured routing entries in the router's routing table to define where to forward network packets destined for specific IP address ranges or networks.
