I have factory reset my router to see if there could be a problem between these two, which I highly doubted there could be but I did it anyway. After the factory reset, Unraid still disappear from the network after I start the docker service (with no installed dockers)
I have attached a disgnostics file right after I rebooted the server with the docker service enabled.
This is what I did : Deleted docker.img, restarted the server with dockers enabled. Waited for the server to restart and for the docker service to start. once I saw that the server disapeared from the network, I stopped the docker service and the server reappeared. Then I created the disagnotics file.

When I go back to 6.9.2 and restore my config, everything works fine with dockers enabled...
