Residential gateway
A residential gateway is a small consumer-grade
Devices
Multiple devices have been described as residential gateways:
- Cable modem
- DSL modem
- FTTxmodem
- IP-DECT telephone (base station)
- Network switch
- Smart home hub
- TV/VoD set-top box
- Voice over Internet protocol (VoIP) analog telephone adapter
- Wired router
- Wireless access point
- Wireless router[1]

- A USB modem plugs into a single PC and allows a connection of that single PC to a WAN. If properly configured, the PC can also function as the router for a home LAN.
- An internal modem can be installed on a single PC (e.g. on a PCI card), also allowing that single PC to connect to a WAN.[6] Again, the PC can be configured to function as a router for a home LAN.

Many modems now incorporate the features mentioned below and thus are appropriately described as residential gateways, such as some Internet providers which offer a cable modem router combo.[7]
Features
A residential gateway usually provides
- configuration via a web interface,[8] or app on mobile device.
- routing between the home network and the Internet.
- connectivity within the home network like a WLANbase station.
- network address translation (NAT),[9][10]
- and
- firewall functions[10]
It may also provide other functions such as
Most gateways are self-contained components, using internally stored firmware. They are generally platform-independent, i.e., they can serve any operating system.
Wireless routers perform the same functions as a wired router and base station, but allow connectivity for wireless devices with the LAN, or as a bridge between the wireless router and another wireless router for a meshnet (the wireless router-wireless router connection can be within the LAN or can be between the LAN and WWAN).[13]
Security
Low-cost production and requirement for user friendliness make gateways vulnerable to network attacks, which resulted in large clusters of such devices being taken over and used to launch DDoS attacks.
