Cannot reach wired cameras from HA

Hi!

I’m running HA on a RPi3b+, connected by wire to a router. I also have three Reolink cameras on my network. One Wi-Fi and two wired. The problem is, although the cameras are reachable from outside my network, from inside HA I can only reach the wireless one. I’ve tried using ping from within HA but the cameras (wired) does not respond.

When using nmap they wired cameras do not show either.

All the three cameras, as well as my HA Rpi, are visible in my router (all have reserved ip addresses).

Does anyone know what’s wrong? What more info needs to be provided for you to be able to help!
