I have set it to go via OpenVPN to be able to view and access externally (outside my local network), and I no longer use P2P:
1. I turned off the P2P service on my NVR.
2. On my TP-Link Archer AX73 router, I enabled OpenVPN Server and then generated and exported a configuration file that I copied somewhere to the mobile phone.
3. On the provider's ONT router, I forwarded only UDP port 1194, which is required for the Open VPN service .
4. I downloaded the OpenVPN Connect application on my mobile phone and loaded that configuration file, and now when I access via DMSS from the outside, everything works flawlessly and there is no more chopping and stopping of the stream!
