A further update... If I do an NMAP scan of the camera IP it's not showing any ports open at all.

Has anyone managed to get an RTSP stream from a C100 with the 1.0.10 firmware?

@CT800 

Good day.

Do you want to live view the camera locally or remotely?

---If remotely, Have you opened port 554 for the Tapo C100 on the VR2800?

---And could you please also check the internet IP address on VR2800 a public IP address, not a private one?

Have you checked if you could live view the camera locally when the computer is located behind the VR2800?

And Are you able to ping 10.50.10.106/111 on this computer?

Thank you very much.

@Brook  Hi, thank you for your reply.

I am just trying to view the RTSP stream locally, so there are no firewall issues. 

A ping of 10.50.10.106/111 gives the result "Ping request could not find host 10.50.10.106/111. Please check the name and try again."

As mentioned in the earlier post, I am not able to ping the camera at all & scans show no ports open. This is the same for both new cameras.

OK, this is even more strange. I plugged both cameras back in today. I haven't changed anything on the router and the only thing I can think is different is that I'd removed the micro SD cards from the cameras (Kingston Endurance 32GB Class 10). I can now ping both cameras and I'm able to stream from RTSP port 443.

Having scanned both cameras with NMAP, both cameras show open ports on 443, 554, 8800 & 2020. Strangely, one of the cameras also has port 20002 open. I'm not sure why this is only on one camera...?

I've put the SD cards back in the cameras & the ports have remained open. I'm not sure why the ports weren't opened initially? The Firmware version still shows 1.0.10. The build version is 200519 Rel 66820n(455), but I didn't take a note of this before.

Im having the same issues rtsp feed comes and goes. Ping is the same when I get a feed ut also replyes to ping. I leave vlc on, and eventually it will connect but its annoying to deal with. Anyone with same issues?
