Reolink is not able to play Preview in WebIF when behind Router

[TheManWithTheCam]

Hello,
i have a Prob with my RLC-823A and RLC-811A. But i feel other models should be affected too.
The Webpreview is not woking when a router is between the cam and the client who wants to show the preview.
The Network looks like this:


The Error is an HTTP 500 when requesting the flv ressource.




Unfortunately Reolink was not able to reproduce this issue (which i can not understand). Perhaps you can check if your Reolink products work ok throuht a router in a lan?
I would always recommend running such cameras on a separate network to protect your lan from potential camera security issues.

@themanwiththecam What's the firmware version of your cameras? Can you check if you have enabled the network ports? You can read this article to enable the network ports, https://community.reolink.com/topic/3183/why-do-i-fail-to-access-the-camera-via-the-web-browser-or-connect-to-the-third-party-software-after-upgrading-my-smart-cameras-with-the-latest-firmware-v-3-1-0764-v-3-1-0804.

@reolink-fiona
FW is v3.1.0.764_21121708
Of course alle Port are open, since it works when there is no router in between. I also opened a support Ticket #747315 but unfotunately reolink was not able to reproduce my problem. So i want to ask the community if they have the same issues...
