I have a network traffic problem.
At my cabin I have a TP-Link TL-MR150 4G router, FW updated in september.
It’s a fairly simple HA installation, using cloudflared for remote access.
It all works very well, but:
The 4G network traffic is over the top. All the time. It will get close to 13GB in december, and I haven’t even been there. There are no web based services, everything is local, just a few temperature and lighting automations.
- The Cloudflare dashboard says that the total bandwidth, last 30 days, is 736MB. Makes sense.
- The TL-MR150 integration in HA says 9740MB in december.
- My 4G ISP says I’ve used 10GB in december.
Could it be a NAT Loopback problem? My TL-MR150 doesn’t have NAT loopback functionality, I think (which is surprising and silly for a 4G router).
I’m very confused!
Experts, please: What is wrong?
