Hi all,

I have the Ultimate Broadband UFC (Fibre to hub, coaxial to home) package with a UltraHub (configured as ). I want to remove the double NATting that is happening with my Nest Wifi 6 router / mesh network.

My WAN settings are as follows:

IIRC the UltraHub doesn't support bridging mode and so playing around with switching NAT off etc won't work?

Has anyone had success with swapping the UltraHub with something like a Draytek router and enabling bridging mode?

HFC = hybrid fibre coax doesn't use PPPoATM so they would be lost.

EDIT: So you have a cable modem connecting to WAN interface of the UltraHub?? or you have an ADSL connection over copper phone lines??

Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.

HFC Coax DHCP with VLAN 10 / or (Old TCL connections) Static IP with manually configured subnet mask and gateway

Thanks both, I had a PEBCAK moment :-), when I double checked my WAN settings I realised my active WAN connection is actually fibre not ADSL. I've edited my question above!

Are you sure that the Nest router doesn't support the vlan tag?? If not then use a managed switch to remove the tag.

Fairly sure the recent Nest gear supports VLAN tagging on the WAN, so just set VLAN 10 / DHCP and dispense with the UltraHub altogether, unless it's also doing a VoIP line.

If you are using the UltraHub for VoIP as well, you can probably just disable the VLAN tag on the WAN and connect it's WAN to the Nest LAN so it picks up an internal IP

If your Nest router has a fire wall you could set its ip address as the DMZ device in the Ultra hub. I've done this in my network with an edge router.
