Just as that title suggests really, it turns out I'm double NATed and I can't quite work out why.
My simple is fairly convoluted, but I can't see anything that should be causing the issue I'm seeing.
Symptoms: I appear to be double NATed. For example, if I look in my Netgear D7000's settings I see an external IP of 172.16.x.x. When I look at something like whatsmyip.org, I see 1.85.24.x.x which obviously shouldn't be happening.
It's causing chaos with things like Plex, and I'm fairly sure it's what is causing the wife's intermittent connectivity issues for things like Slack in the home office.
Setup:
ISP: Origin Broadband VDSL.
VDSL Router: Netgear D7000 all updated etc. It has NAT etc turned on, and it's obviously the first thing connected to the outside world. This serves devices via Ethernet and both 2.4GHz and 5GHz WiFi hotspots.
Network kit beyond the Netgear:
TP-Link AV1000/2000 home plugs. I can't remember which of the two models it is, but it doesn't really matter for this issue. One in the living room where the Netgear is, the other in the home office.
TP-Link Archer C2 WiFi Router in the home office: This extends the existing WiFi access points. Same SSIDs, and takes the connection from the home plugs and turns it into WiFi. The TP-Link is configured with DHCP and NAT DISABLED. This should not be causing the issue as far as I can tell, and the issue does not appear to go away with it turned off.
Sky Q Silver and additional box: This is where I wonder if things are getting a bit messy. The Silver box is connected to the Netgear directly, and the additional box is connected to the Silver box via its own Ad-Hoc network. It should not be touching my network except for downloading content/online services. But I do wonder if this is creating its own NAT somewhere along the line. I need to try powering the whole lot down when the kids will let me!
There are various WiFi devices connected - phones, tablets, notebooks etc. Again, no good reason why any of that should be causing an issue. I can't see why it would.
So that's about it. Any thoughts as to what's going on here? I could understand the double-NAT if there were DSL modems and extra routers hanging off them, but I use the Netgear to avoid all that.
Thanks all - it's getting on my nerves!
