Hello,

I'm blocked trying to configure my NVR & 4G router to allow remote access from gdmss app.
I discovered that my provider blocks inbound traffic (port forwarding does not work: I tried to configure port forwarding + ddns on my Huawei B315 but unable to see open ports from a remote location).
Maybe a VPN could help but I'm not familiar of these techniques.

Then, I tried to scan the QR code displayed by the Easy4IP section of the NVR from the gdmss app ... And it works. Honnestly I don't understand why !!

Any idea to configure a proper & pretty secure remote connection ?
