Someone familiar with the Chrous ONT and port forwarding able to assist?

The Deco is connected to the Chorus ONT. The Deco is in Router mode using IPTV/VLAN.

I get a 100.xx.xx.xxx IP address (Dynamic IP) but https://whatismyipaddress.com/ gives me a 161 address.
So apparently the Deco isn't getting an external IP? Is the ONT set as a router by default?

I have to use upnp otherwise I don't get the green tick for the port being open on uTorrent

and any Port forwarding I try doesn't seem to work but weirdly on the Vodafone Ultrahub I had zero problems however the HG659 and the Deco aren't playing ball.

Do I need to connect up the ONT directly to a PC login and check it's networking options? What should it be set to?

Presumably this issue is your ISP is using CG-NAT for IPv4.

EDIT: What ISP are you using?

CG-NAT related and not related to Chorus

Hi the chorus ont is a purely layer2 device and has no partition in port forwarding. Clearly you have no idea

Sounds like you're ISP is offering a CG-NAT solution therefore port forwarding is not an option.

The ONT is not in ant involved in port forwarding.

If your ISP uses CGNAT then port forward won't work.

What ISP are you using?

Seems the previous posters are big fans of redundancy. So allow me to be the fifth person to tell you that CGNat will cause you problems with port forwarding.

And don't forget the ONT has nothing to do with it. Was this mentioned before?

Oh, it might be CG-NAT. Surprised that nobody has mentioned it yet.

Thanks guys, I think it might be CG-NAT, If someone else can confirm that would be appreciated :)

I'm using 2degrees but previously I was using Vodafone. I'm aware Vodafone does not use CG-NAT but I had port forwarding issues there for some reason..

Any way around it besides uPnP? or requesting IPv6/Static IP (which I think costs extra?)

Request a static IP address but that does cost $10 per month

2Degrees now uses a CG-NAT address for all connections unless you pay for static IP. I believe all 2Degrees connections have IPv6 included, but that's only going to help if the incoming connections are from something that also has IPv6 access.

Ideally I want to be able to offer full download speeds from my Synology NAS, would setting up a VPN get around Quickconnect's limited speed or does that require ports being opened as well?

As I’ve said multiple times on here look into Tailscale. Works no problems (and quick) behind CG-NAT. There is an official package for the Synology you can install. Tailscale is free and very good.

You don’t actually need a static IP here for your use-case.

I read about that on Reddit where someone recommended it. If I remember rightly though it requires installation on the pcs connected to it? I don't want others ideally to have to install stuff.

Here is another option if you want to access your NAS from outside:

Use one of your domains on Cloudflare
Install Cloudflared on your Synology
use Cloudflare Zero Trust Access to configure tunnels pointing to subdomains without the need of port forwarding
use Cloudflare Zero Trust Access to create groups to allow only certain people to get to those subdomains

This works with browser-based services only. It won't do anything for your torrents.

Nice thanks, I'll give it a shot. I'll keep UPnP enabled for torrents.
