Kia ora,

Apologies, I'm at the edge of my technical abilities here, but will do my best to describe my issues.

I have the following set up:

ONT -> Vodafone Ultra Hub -> TP Link Deco X20 -> W11 mini PC (Plex media server)

The UltraHub has wifi disabled and is only being used to pass connection on to Deco X20, which has much better wifi. All other devices in the house connect to Deco X20. Both UltraHub and Deco are running stock settings as far as I know.

I have the following problem:

I can't get the remote access to work properly in the Plex media server due to a double NAT issue. Presumable this is because Ultra Hub and Deco X20 are both assigning local IP addresses at different levels.

From reading threads, I know the Ultra Hub can't be set to bridge mode.

Can anyone help suggest the simplest way to deal with the double NAT issue in this set up? I phoned One, but they couldn't help. Thanks so much for any help you can provide!

If you don't have a home line with One NZ, you can remove the UltraHub and plug the Deco into the ONT.

Thanks Delorean!

We just have naked broadband, no landline. So I should be able to remove the Ultra Hub entirely?

Do you think I'll need to do anything more than just plug the Deco into the ONT directly?

Thanks again

2 solutions

1 if no home line remove the UltraHub and enable VLAN Tagging for NZ UFB on the Deco X20. Plug it in. Double NAT gone.

2, if you have home line, change the Deco X20s to just Access Point only, Double NAT also gone.

As per MaxineN comments - Just need to enable VLAN 10 and job is done

Thanks! I've just tried this, and the connection seemed to work (well, I didn't check the double NAT thing yet), but interestingly my download speed dropped from about 450Mbps to under 100Mbps.

What I did:

removed UltraHub
under advanced settings, I enable "IPTV/VLAN" and set mode to "New Zealand UFB"
When I did this it entered two more values that I can't change
- Internet VLAN ID = 10
- Internet VLAN Priority = 0

Any ideas why there would be such a drop in performance?

Are you hitting something like 95mbps? If so yeah 100mbps link rather than 1000mbps and it's a faulty cable.

Thanks - it's the same cable that connected the ONT to the UltraHub, it just now goes to the Deco.

I disabled IPTV/VLAN and put the UltraHub in the middle again, and speeds went back to just under 500

Are your Deco X20 units running Ethernet or wireless backhaul when Ultrahub was removed? If wireless, then it will reduce your speed. Always connect the mesh units via Ethernet where possible for best performance.

Mōrena,

Thanks everyone for your help, I've somehow solved it despite myself.

Last night I played around with it some more. And it was really clear, when I removed the UltraHub and switched to VLAN, it again had a drop in speed; put the UltraHub back in, speed returns to full.

I left it in VLAN for a while and inexpertly played around with other settings, most of them broke things completely. In the end I reverted everything to the original VLAN/NZ UFB setting, and suddenly I was getting full speed! No idea what happened, but it all works without the UltraHub now, double NAT issue sorted! Thanks for your help.

In the end, this is such and easy fix and lets me remove an entire piece of hardware - any idea why Vodafone (One) couldn't (wouldn't?) have suggested this fix?

We don't market/promote the X20s as part of the super wifi promo to replace your current RGW. Only to extend and compliment (also because of how our voip works we need you to keep the RGW in place if you had a phone line).

In the same vein we also say you should turn off the wifi of your RGW as well.

None of the less glad it's resolved :)
