Contact is not offering help over the long weekend and I have remote work morning starting tomorrow, so I'm reaching out to see if anyone has any ideas.

I've been living in the UK and I have my Asus Nighthawk router set up for all my PC's and so I would prefer to use it.

Back in the UK I just told the virgin modem-router to go into "modem only mode" and the nighthawk took over. I was kind of hoping something similar might exist in this NF18ACV?

On the modem interface gateway I see it has the following options:

PPP Over Ethernet (PPPoE)

IP over Ethernet (IPoE)

But I'm unsure if that is relevant. I could not see any other option that would indicate there was a modem only mode.

Advice welcome :)

It will probably work if you turn off the wifi on the NF18ACV, and then connect your Nighthawk to it LAN-LAN, but turn off NAT and DHCP on your Nighthawk. It is often less hassle to let the ISP modem do the Routing/DHCP server/NAT stuff.

I have also set up firewall rules to allow my Synology NAS to be seen from outside on the Nightwalk, will that be lost if I let the ISP modem handle DHCP server/NAT stuff?

Have you checked if you can configure the netgear to be the router and just plug it straight into the ONT? You dont really need to use the ISP provided one unless you're buying their phone service to allow boomers and scammers to call you.

Be aware that Contact Energy use CG-NAT which means that external access via port forwarding will not work. And as mentioned you need to remove the NF18ACV from circuit and configure WAN interface on your NightHawk with IPoE (which means a DHCP client) tagged with vlanid=10.
