Any luck with this? I had no issues playing Splatoon 2 or Mario Kart online before. I played a few games of Smash Bros on the night it released and it also worked fine. My Virgin TV was screwed so an engineer came out to fix it and ever since then my Switch has had NAT type F and can't play anything online!?
What the hell did the engineer to to my superhub to screw this up?
I have tried port forwarding and setting a DMZ and I'm still getting NAT type F.
<SNIP As long as your not in the IPv6 Trial, or Northern Ireland, then UPnP/UPnP should be all that's needed.<snip>
I'm curious why UPnP would not work in Northern Ireland ? Is this a legacy hangover from NTL ?
I am fairly sure NI has had IPv6 rollout with CGNAT as the solution. Quick test would be if any IPv6 sites work, if so then CGNAT is the problem here.
So IPv4 going Forwarding is not going to work any longer sadly. It's probably worth going to boards.ie and asking for help there as I think the staff can move you back to a IPv4 ONLY connection (No IPv6) where port forwarding still works.
---- I do not work for VM, but I would. It is just a Job.
I would also make websites for them, because the job never seems to require the website to work.
I think you might be referring to Virgin Media Ireland which operate in the Republic of Ireland; Northern Ireland is still serviced by Virgin Media so won't get the IPv6 rollout until the rest of the UK does.
I called them. Have not tried their online chat, not sure how far you can get. But a phone call telling them you will change providers unless a new router is sent FOC will quickly get you sorted, which you have good reason to threaten considering I have seen no other ISPs with this NAT issue for Switch.
