Orbi NBN connection via Netcomm AC modem (Aussie Broadband FTTN NBN)
Appreciate any help to setup Orbi to connect to Aussie Broadband FTTN NBN via supplied Netcomm AC modem router. Understand that I can connect with Orbi setup in AP mode but read somewhere that I will...

Just to update. Aussie Broadband replied that they do not support bridging setup on th netcomm modem/router due to the complexity of the settings setup between devices. They adviced me to contact Netcomm directly for the help.
On the Netgear Orbi, they indicated that it should just require to be setup with a DHCP connection and where it says "Does my connection require a login" select No.
The access point setup with Orbi seem to be working ok so did not have a real need to play around with modem bridging yet.
That proceedure is complicated so it's not surprising ABB elect not to support it (a bit disapponting though).
The settings they specified for the router are the most common ones used by ISPs for NBN, that sounds sensible.
If your happy with AP mode then that should work well too, but you do loose some of the functionality of the Orbi in that mode.
OTOH if you need the VoIP functionaily for you phones then this the simplest way to keep your phones working with the NBN without buying an ATA as well.
Setting my iiNet device to bridge mode was a bit difficult too but it works for me.
I also purchased another inexpensive modem/router (Dlink G225) and set it to bridge mode and it also works fine with iiNet NBN (but even that was slightly difficult to set to bridge mode).
It might be worth asking ABB how to reset the Netcomm to it's original settings (that work with ABB) so you could try out the bridge mode settings and if there's a problem perform the reset to restore it. You would hope that resetting it to factory defaults would be all you need to do but checking with ABB first on that would be the smart thing to do.
I backed up the settings for the Netcomm modem/router just in case. Wouldn't that work to restore ABB settings if my experiment with other setting doesn't work?
BTW, I am still unclear of the functionaly lost from Netgear Orbi when setup in AP mode. Thought there was benefit like not having to do the switching (DHCP handled by Netcomm) help free up processor at Orbi side. What's the downside of using Orbi in AP mode?
Probably a newbie question. For DMZ setup, do I turn off DHCP at Netcomm side and turn it on at Orbi side?

Backup/restore should work fine.
I haven't had my Orbi in AP mode for a long time so I can't remember the details.
You won't be able to use things like parental controls and probably not MAC filtering either.
I'm not sure how functional devices list is in AP mode ...
In AP mode the Orbi is just another device so DHCP and other router functionality is disabled when it's switched.
If you use DMZ to get the internet packets forwarded to the Orbi you wouldn't turn off DHCP on either device.
All this is meant to do is make the modem/router send all incoming traffic (for which it has nowhere to send it) to the Orbi.
There are a couple of things to be careful of.
The Orbi needs to be on a different network (eg. Netcomm 192.168.0.0/24 and Orbi 192.168.1.0/24) to the modem/router so that incoming packets can be properly routed to it.
Using this setup will introduce what is called Double NAT which can cause a problem for certain usage types, for example UPnP won't work with this setup so games console might have problems.
