PostgreSQL is running in a docker container:

$ docker ps CONTAINER ID        IMAGE                         COMMAND CREATED             STATUS              PORTS                    NAMES 6f11fc41d2f0        postgres                  "docker-entrypoint..."   4 days ago          Up 4 days           0.0.0.0:5432->5432/tcp   postgres $

The various docker interfaces and virtual bridges are not assigned to any specific zone.

Why is port 5432/tcp open?

You will see it if you check the netfilter rules with:

iptables -L -n -v --line -t filter iptables -L -n -v --line -t nat
