Very welcome to SNB!
If you enable all black-lists
, you risk that the memory of the R7800 will become full, and the router not working.
I suggest you use NO black-list to start with.
Then add a specific address to your private black-list and try if it is blocked.
Then check one black-list, eg MVPS.
If you refresh the page, you will see how many addresses that are in the black-list.
The DNS status is reporting cloudflare.com, and that is the address that is pinged to test the DNS.
As a beta tester I now expect you to try figure out what is wrong and then report your progress here for everyone to learn.
I'll try to fix bugs you encounter, of course!
