When enabled, port forwarding (IPv4) and port opening (IPv6) let traffic from the outside world (the internet) pass through the Google Wifi firewall to a specific device on your home network. Don’t worry: this only happens when you turn it on and only with a device of your choosing.
Set up port forwarding/port opening
1. Open the Google Wifi app.
2. Tap the tab, then Network & general.
3. In the ‘Network’ section, tap Advanced networking.
4. Tap Port management.
5. Choose the tab for the type of IP address you’re forwarding, IPv4 or IPv6.
6. Select the device you want from the list and tap Next.
6. For IPv4: Enter the WAN starting port, then the port range.
For IPv6: Enter the port range.
Note: Some devices will suggest what ports to use, while others let you choose. If you don’t know which ports to forward, contact the manufacturer of the device or check their manual.
7. Choose either TCP, UDP, or TCP and UDP. These are different protocols used to send data over the internet.
8. Tap Done.
