Wake on Lan + WiFi Mesh

I recently added a wifi mesh appliance to my home WLAN to enforce wifi signal in rooms more far from router. As soon as I did it I experienced problems with AppleTV and aTV app on iPad: I use both to view videos stored into aTV app soon my iMac (macOS 12.6.6).

The problem is that if iMac is in sleep mode AppleTV or iPad aren’t able to connect the library.

I think the real issue si that WakeOnLan signal (or Bonjour, I don’t know…) is blocked by mesh appliance. 

I experienced the same issue if I try to connect iMac using a VNC connection.

Which mech appliance configuration is needed to enable AppleTV or other device do wake up iMac?
