Macvlan network do not work and do not appear in my home router

Hi,

I am trying to create macvlan network for use with containers that need to access UPnP devices on my home network. A year ago, I did exactly that it “just worked”. Now, I can’t get it to work again. I am configuring the following using compose:

networks:
  macvlan:
    name: macvlan
    driver: macvlan
    driver_opts:
      parent: eth0
    ipam:
      config:
      - subnet: 192.168.50.0/24
        gateway: 192.168.50.1
        ip_range: 192.168.50.0/24

My container is correctly connected to this network.

But nothing happens on the host nor in my router. I remember that when a container was connected to the macvlan network, in my home router I could see its mac address appearing, alongside the one of the host itself. And it worked with UPnP.

But now I don’t see anything appearing in my router, and the UPnP devices on my network don’t see the container. I also tried with an ipvlan type network, with the same results.

I know very little about macvlan and home networking in general, so there might be something I don’t get. But I can’t find if the issue is with my network configuration or with the host.

Could someone help me ?
Any answer is welcome
Have a nice day!

Note : networking mode “host” works, but that is not the desired goal because it blocks me from connecting to other docker networks in bridge mode. I successfully got it working with macvlan in the past so it should still work
