Model: Deco X50-5G  
Hardware Version:
Firmware Version: 1.0.1 build20241211

Previously, I had a standard router wired via the copper network.

 

To view my locally recorded videos, I had enabled port forwarding.

 

 

 

However, I switched to a 5G router (TP-Link Deco X50-5G).

 

Since then, even with port forwarding, I can no longer view my videos outside my home network.

Hi, yes, I'm afraid so.

Many mobile service providers use CG-NAT, and there isn't a public IPV4 address available for Port Forwarding/OpenVPN server features.

CG-NAT Blocks my OpenVPN and restricks the NAT type

 

Thank you very much.

Best regards.

In my 5G router, I have an IP address of 10.xxx, and when I go to https://whatismyipaddress.com/,

I have an IP address of 178.xxx, so I have a NAT layer (CGNAT) managed by the operator? Is that the problem?

So I also tried to configure OpenVPN so that my smartphone can access the home network via OpenVPN outside the house. So I tried to create a server from the app as described in the FAQ. Then I exported the configuration file to put it in the OpenVPN app for my client (smartphone), I have the impression that the server never gives a response. It's the same cause ?
