Whatever state is in FreeBSD ports first full week of January is going to be in 20.7.8. Threads in the forum with multiple workarounds regarding this already exist. My favourite scenario would be that 1.13.1 is released soon...
1.13.0_1 is now part of 20.7.7. We will continue to monitor for newer Unbond versions but for now that will be everything we can possibly do.

Describe the bug A bug in Unbound causes it to crash with a segmentation fault which renders DNS resolution inoperable on the network. The bug is described here: https://github.com/NLnetLabs/unbound/issues/376
On the 17th of December, a fix for this was committed to the FreeBSD ports tree with version 1.13.0_1: https://svnweb.freebsd.org/ports/head/dns/unbound/?view=log
Personally, I think this is well worthy of a hotfix because today a client called me saying that his network was down and the cause was this bug.
I also saw it mention on the FreeBSD forums: https://forums.freebsd.org/threads/libunbound-error.78121/
To Reproduce I do not know precisely how to reproduce this. My client said it happened a few days ago and he rebooted his router, today it also happened at random. I checked his log file and I saw this error happening literally every second:
[69515:1] error: udp connect failed: No route to host for 2600:9000:5302:e300::1 port 53
Expected behavior Unbound not crashing.
Environment OPNsense 20.7.7_1 (amd64, LibreSSL).
