# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://how.router.works/net.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
