Imou rex cam and rtps stream

[seboost]

Hello,

I have one (several?) network problem with my imou rex cameras.

I have retrieved the rtps stream from the form rtps:/adminassword@192.168.x.x:554/cam/realmonitor...onvif, if I put this url in vlc, I can access the video stream without any problem.

If I replace the local address by the ip address of my 4g router (a cudy lt450), having redirected the port 554 on the local ip of one of my cameras, when I enter the url rtps:/adminassword@ipv4(92.23.xx.xx):554/...onvif in vlc, impossible to get the video stream...

I did some research, redirected the port 80, 8080, 5002, 5003 ... still nothing.

I'm not sure how to access this stream from outside, first for one camera, then for several, knowing that I think the video stream always goes through port 554 for all the cameras and that I can't access any management interface for my cameras...

Could someone help me?

Even though the router specs state port forwarding is available (not a good idea), the ISP may employ CGNAT (Carrier Grade Network Address Translation) as most cellular 4G/5G carriers do, meaning no WAN public IP is available so you can't get to your LAN from outside with conventional means. A phone call or online visit with your ISP should shed some light on that.

If CGNAT is, in fact, employed by your ISP, consider a VPN such as Zerotier.
