VDSL 4g backup ISP modem as bridging mode with Google NEST WIFI

[ramjip]

Hi,  I'm receiving a VDSL (4g backup on outage) ISP modem.  Do I need to setup as bridging mode?  Or can I just turn off NAT alone.  Because.  ISP modem has feature of 4g backup on VDSL outage.  I don't want to loose this functionality.

Hi ramjip,

Bridge mode is generally not a hard requirement. However, it usually solves issues you may encounter with a double NAT configuration, such as port forwarding and UPnP not working as expected --especially in games.

Since your ISP-provided modem has a failover feature that switches to 4G in case of failure of your NBN broadband line, I'd recommend first to set up your Nest Wifi without enabling bridge mode, in order not to lose the feature. 

Disabling the Wi-Fi of your ISP-provided NetComm modem/router combo might also be a good idea to avoid wireless interference with your Nest Wifi network.

Thanks Gradient.

What if I want to use UPnP?  Does that man disabling just NAT would help solve the problem?  Or do I stop few services in the router?

Hi folks,

@Gradient, thanks for the help.

@ramjip, as long as your modem does not have the Wi-Fi capability on, it should be good. Some ISP provides modem with Wi-Fi capability and this needs to be turned off, usually by setting it to bridge mode, to avoid double NAT issues.

@Jhonleanmelstill waiting answers for my questions.

Of course, I will be turning off my WiFi.

Hi ramjip,

UPnP is enabled by default. It allows devices on your network to communicate with less friction, both with the internet and with other devices on your local network. Ideally, we recommend setting your modem to bridge mode to avoid double NAT issues.

Turn UPnP on or off (UPnP is enabled by default)

1. Open the Google Home app .
2. Tap Wi-Fi and then Settings and then Advanced Networking.
3. Turn UPnP on or off.

Best,

Mel

My question is can we use Upnp without bridge mode but disabling NAT alone?

Hi ramjip,

You may need to confirm this with your ISP if this is supported by the modem they provided.

Best,
