Hi, the use-case you're trying to achieve is possible, but there are
some issues with your configuration.

You want to specify "policy.PASS" without the brackets.
and these are the RPZ zones:
$ cat '/etc/knot-resolver/allowlist.rpz':
www.google.com 600 IN CNAME rpz-passthrough.
www.bing.com 600 IN CNAME rpz-passthrough.
When you provide kresd these RPZ zones, it will complain:
[poli] RPZ /tmp/kr_dev/etc/knot-resolver/allowlist.rpz:1: CNAME with
custom target in RPZ is not supported yet (ignored)
It's because you're trying to use unsupported CNAME. See the table in
our docs [1]. What you're probably looking for is "rpz-passthru."
instead. However, if you're using a separate allowlist with policy.PASS
action (which is your case) "." would also work here.
You should also be able to combine the blocklist and allowlist into just
a single rpz file, using policy.DENY_MSG("...") and controlling whether
domain is blocked ("CNAME .") or allowed ("CNAME rpz-passthru.") with
the RPZ rules themselves.
