21.7 Legacy Series / Unbound issues
« on: September 11, 2021, 08:56:20 pm »
While running Unbound as a local resolver, I had come across three issues:
1. Unbound fails to resolve certain domains. I have no DNSBL in Unbound. Unbound only delivers the CNAME, but no A record. When using Unbound as DoT forwarder, it resolves the hostname normally.
2. Even though I have unchecked "Flush DNS cache during reload", the statistics and cache are cleared with every Unbound reload. This should not happen.
3. Unbound failing to start, see https://github.com/opnsense/core/issues/5150 - I don't experience this anymore, though.
Has anyone experienced similar issues or could suggest possible (configuration) errors?
