How to block or filter devices attaching to powerline ethernet ports (alien.top)

Hi,

I'm a regular home user (am not an IT or networking professional).

I have a shed at the end of my garden which is out of range of the WiFi router in the house. Because of this, I use a TP-Link powerline adapter to get network connectivity in the shed and at the end of the garden. The adapter provides both WiFi and an ethernet port.

I'd like to limit/control what devices can connect to the ethernet port of that powerline adapter. In the device settings there doesn't appear to be any options to disable the ethernet port or to perform any allow list filtering of devices connected to that port or to the powerline network in general. I could perform allow list filtering at the level of my main router in my house, but I don't want the inconvenience of applying this to my whole network. The ethernet port on the powerline adapter outside the house is the only one I want protection on. I'm not worried about the WiFi network or any ports inside the house.

This leads me to a couple of questions

Are there any powerline brands which provide ability to do allow list filtering at the level of the powerline network itself, provide ability to disable individual ethernet ports on powerline adapters, and/or sell adapters which are WiFi only (no ethernet ports).
I suspect there is probably something I can install that sits between my main router and the powerline network to enable me to perform allow list filtering of devices attached to the powerline network without having to do it at my main router. But I'm not sure what that would be or what to read up on to set it up. I do have an old spare router in case it could be used for this purpuse.

Any help or guidance would be much appreciated.

Thanks

Whitelist the devices on your network, to only allow known devices. You would do that on your router.

The problem with that is the OP would have to whitelist every device in the entire home, every phone, camera, smart switch, AND every a visitor comes over and want to use their network. It's just not manageable for most people.
