    Thank you everybody for your help, especially u/thisischemistry. I finally found a solution. My problem was the rtsp link that was not correct. The path depends on the brand of the camera. I went on ispyconnect.com where you can generate the correct URL base on you camera's brand. And that was it ! Magical :). Source: almost 4 years ago

    What external access are you talking about? If you mean access from ispyconnect.com then use that switch - if you mean access from the LAN you'll just need to block the 8090 port with the firewall. Source: almost 4 years ago
