The change in `/etc/firewalld/firewalld.conf` of `DefaultZone=external` to `DefaultZone=public` seemed suspicious since, according to my notes, I had never touched that file. Choosing to accept the packager maintainer’s version when I [attempted](https://discuss.freedombox.org/t/update-when-to-panic/2608/11) the manual upgrade (selecting `Y` at the conffile prompt) seems to have been the wrong choice for me. That said, I noticed that one of my FreedomBoxes that did successfully automatically upgrade without any issue (besides a [minor Mediawiki hiccup](https://discuss.freedombox.org/t/mediawiki-upgrade-notes-bullseye-to-bookworm/2609)) ended up with `DefaultZone=external` in its `firewalld.conf` file.

The box that had a successful automatic upgrade from Bullseye to Bookworm (originally spun up 2022-09-01) now has 3 files in `/etc/firewalld/`:

- `firewalld.conf` with `DefaultZone=external`. Modified 2023-06-11.
- `firewalld.conf.old` with `DefaultZone=public`. Modified 2023-01-06.
- `firewalld.conf.dpkg-old` with `DefaultZone=external`. Modified 2022-08-17.

The FreedomBox that had the failed upgrade to from Bullseye to Bookworm (originally spun up on 2022-05-09) and which I reverted to an evening backup had in its backup image:

- `firewalld.conf` with `DefaultZone=external`. Modified 2022-05-09.
- `firewalld.conf.old` with `DefaultZone=public`. Modified 2021-02-01.

When I next attempt an upgrade, I’ll try making sure `DefaultZone=external` remains in `/etc/firewalld/firewalld.conf`.
