I've spent the better half of the last two days trying to sort out my NAT type (from moderate to open) on my PC with little to no success. Things I've tried so far include:
Static IP address: No change
Port forwarding: All the recommended ones except 53 because I can't: moderate NAT
DMZ: Tried to set that up: moderate NAT
Switching uPnP off and on again
Wired connection to hub: moderate NAT
Disabling router firewall: moderate NAT
Disabling router firewall & Norton TV firewall: Open NAT temporarily
Re-enabling Norton TV firewall: Strict NAT
Re-enabling router firewall: Strict NAT
Re-setting everything back to normal: Moderate NAT
All attempts include restarting computer and router
I've been round in circles too many times now and have kind of lost what I need to be doing to fix this.The port forwards are still set up and I'm basing whether I have the correct NAT setting on the windows settings page:
Settings>Gaming>Xbox Networking>Xbox Live multiplayer NAT type
Occasionally I also get the "Teredo is unable to qualify" script which tends to disappear if I check my NAT type again or hit the "fix it button in the settings.
Does anyone have any other recommendations? Anyone familiar with Norton TV or any interaction between the Norton & router firewalls?

I found the UPnP on the SH3 to be terrible. But i am glad to say my ASUS does it a whole lot better, on PC and PS4. I am on NAT 2 for both.

I'm not against buying a better router so long as it solves the issue.
But can I rule the issue down to the router? I'm concerned it has something to do the multiple firewalls from Norton & the router and I'm not sure that a new router would fix that.
@Athollian Put the hub into modem mode and connect just your gaming PC, this will show you what is achievable without the Hub 3's infamous routing in the way. If this gives you the desired result then a good third party router should solve the issue. If it does not work then the issue lies with something on the PC (probably Norton) as in modem mode you are getting unfettered access direct to the Internet.
My setup: V6 TV box, M350 Fibre broadband with Hub 3 in modem mode connected to a Netgear R7000 router. Telewest/VM user since 2001.
