Unbound DNSBL - logging blocked queries

[hfvk]

I know this topic has been discussed earlier but I haven't yet found a solution for this.

So, I am on OPNsense 20.7.7. I am using Unbound and DNSBL to filter DNS queries. I have enabled Advanced Settings / Log Queries and I have also set loglevel to 5. I am not still seeing from the log what queries are being blocked.

Does anybody have any idea how to check what queries are being blocked by the DNSBL blacklists?

I have to say I'm curious about this as well. Sometimes a certain website doesn't work anymore and it's difficult to see wether it's the firewall, VPN, DoT or DNSBL. Or something completely unrelated.

is this perhaps the same issue as: https://forum.opnsense.org/index.php?topic=20516.0   ???

Can't speak for the TS, but for me personally it's more a feature request or general questions than a specific problem I have.

And yes I had the unbound instability issues with 20.7.7 but thanks to the topic I reverted to the old unbound version weeks ago.

This is not an answer to Unbound blocklists, it is rather that I currently uses DNScrypt-proxy and it has a logging function just as you request. And DNSBlock lists.

Until I get Unbound to not restart all the time, which is an issue in my config with DNS block lists, I will most likely stick with DNScrypt-proxy. However as soon as Unbound and OPNsense stops with restarts all the time, I will change back to Unbound.

looks like patch works well
(https://forum.opnsense.org/index.php?topic=20516.msg95675#msg95675)
on my test vm unpatched version works stable with verbosity level 0 or through DoT forwarder

unbound itself not logging "resolved" address(es) at any verb level.
its FR at github for changing "local-data 0.0.0.0" dnsbls records to "local-zone refuse".
i have tested suricata alert for this. works

I am new to OPNsense /Unbound and I am looking for an explanation how to read the logs.
E.g. to find:
- Request coming from Client u.v.w.x looking for abc.com blocked by blacklistA
- Request coming from Client u.v.w.x looking for abc.com resolved from cache with 1.2.3.4
- Request coming from Client u.v.w.x looking for abc.com forwarded to 8.8.8.8 and resolved to 1.2.3.4

Is there any way to get this information from unbound ?
