I will try again soon, but when I had the following setup, blocking did NOT work:
Modem -> Deeper Connect Mini -> Router -> Devices
When I set it up as follows it works:
Modem -> Router -> Deeper Connect Mini -> Desktop Computer
Does it matter what direction/ethernet port I use plugging into?
It is currently work and the router is plugged into the ethernet closest to the power and the other ethernet is plugged into my computer. Just a thought...?
