Thanks for the reply Ian.

As far as I'm aware, that port tester listens for a response from the pcwintech.com server.

I am with Vodafone Qatar, who's technical support is rubbish and online forum is non existant. However I've read this thread from Ooredoo Qatar, where a user experiences the exact same issues as me. His router also receives a private IP. However (this is my take on the thread, I may be wrong!) after setting up his ONT/router correctly, he is able to forward ports and also use a DDNS service to access his computer from outside his network.

As far as PCWintech goes (and I know nothing directly about the software) I believe you are testing to the wrong IP (assuming it is connecting from an external server). The 192.168.0.2 address is internal to your network - nothing outside of your network will connect to your machine on that address.

You need to test to your public IP address. You can check your public IP address with this. Try doing the test to that address and see what you get back.

EDIT : Just having a quick look at that app... Not sure what it is doing with the IP address as it is odd that it has a field for it considering what it appears to be doing. Try doing a port forward to a different port on the router - say port 30000 - just to keep it up out of the way. You need to ensure the forward is to the same computer you are running the test on. Then run the software using that port.

Of course, that may already be what you've done but ideally you want to test a port on that software that isn't already being provisioned by another application.

It would be good to sort out if it really is CGNAT or not. I am coming to the feeling it isn't and it is the modem that is blocking the ports.

EDIT2: Never used this but it may be able to test an open port using your public IP.

It looks like it already checks on that IP. This is the screen during the tests

If I disconnect my WAN, all of the tests fail.

OK, that is proving it is testing the right thing and does suggest you do have some active port forwarding. Is the machine you are running that tool on the same PC as the one running the Mumble application? I assume your port forwarding is set to forward to 192.168.1.2 on port 13337 and that Mumble is running on that same IP?

I also assume you can access the service from another machine on your network on that port (or does Mumble require an external server to operate)?

Yes you're correct. My computer is 192.168.1.2, which is where I'm running the mumble server and port testing tool from.

Correct again - I can access the mumble server from my laptop and phone using both the 192.* address and the 10.* WAN address that my router shows in it's config panel.

Also, my router's routing table shows an IP region of 169.254.0.0. I can't seem to find the actual IP right now, perhaps because of the new firmware, but yesterday I could also access my router's config page and my mumble server using this 169.x.y.z IP.
I don't know if this is either normal or relevant, but I thought I'd mention it.

Running out of ideas here.

When someone tries to talk to you over mumble do they get any error messages?

It feels like something that Vodafone are doing but very difficult to diagnose further from thousands of miles away.

Ha yeah, it certainly makes things difficult. Is there anything I can do and relay to you?

Over LAN, communication on mumble is fine.
When trying to connect over WAN it just says connection error.

As it stands I think you have an issue with Vodafone. But, given their level of expertise I am not sure how you can resolve. You have mentioned that someone else got this working - are you not able to get further info from that source? If it comes to hacking the modem then I can't help as we don't have that kit in the UK.

The other person got it working with Ooredoo. From what I can gather from his thread, his ONT was forwarding ports and then his router was too - causing the problem.
To resolve the issue he logged into his ONT (different make and model to mine. I can't find the IP for mine anywhere) and set his portforwarding rules there, then set his router up as a bridge.
Obviously without the ONT's IP, I can't set any port forwarding rules up there. Vodafone phone support have no idea what I'm talking about when I say ONT, and the technician I had come out to the house said he couldn't configure it or tell me the IP. He rang his supervisor who said the same thing.

I've tried putting my router into DMZ but nothing changes.
