Bear with me here, this may be a silly question! :-D

I'm currently buying and setting up some Ubiquiti gear for my new build (currently 2 x AC PRO's, the 8-port PoE switch and a Cloud Key). Long-term I plan on adding a USG to take over the firewall & router-function that will be carried out by the ONT, so my understanding is that I:

- Configure the USG to run in bridge mode
- Disable the routing aspects of the ONT (DHCP - I believe double-NAT is ok?)

So the ONT effectively is then just a modem. If that's the case, and it's on the WAN side of the USG, how do I browse to it, should I need to trouble-shoot anything? Is is this done by Spark using it's public IP?

The ONT does not carry out any firewall or gateway function - that is the function of the CPE router (USG in your case).

Oh, ok - I'd just assumed the ONT was an all-in-one unit - modem, gateway, wireless router etc?

Nope - you need to have a router sitting behind it that does any authentication, gateway, firewall, AP duties. Not 100% true, but for simplicity sake it's a media converter - optical to ethernet.

The only exception to this for the average user is that some RSPs (Spark are one) use the voice port(s) to provide a voice service. Other RSPs use an ATA (either separate, or built into their supplied router).

You will need a router of some description, be it a USG, or one provided by Spark - without this, no internet! As for browsing to the ONT, you can't. The only troubleshooting is checking the colour of the LEDs, and if it's not right, lodge a fault.

Cool, thanks for clarifying; so the router Spark will provide is likely one of those Huawei models. which I can use from day one (disabling the Wifi of course) to provide gateway functionality etc until I implement the USG?

Yes, that's fine.

That's what I'm doing at home, Huawei router for routing, Ubiquiti AP for WiFi.
