Pi-hole blocking internet access

Unfortunately I cannot configure the upstream DNS. I can only configure what the router distributes locally, so I can choose automatic or manual.

However assuming the upstream DNS are handled automatically, I've configured the rest as per above.

Not sure if this is what was expected or provides any clarity.

Looks like this is the only option given the Vodafone router behaviour.
