Regarding the firewall, at the moment I do not use Docker and I only use the DSM builtin firewall. The rules are set quite tight. There is also a NAT / SOHO router between NAS and the internet with the bare minimum ports open needed to access services on the NAS like poort 21, 80, 443, 1194, 5001, 6690 and 55536-55899. All is well when using DSM builtin MariaDB. No issues.
The issues started when I deployed the official MariaDB Docker instance. I have a bad experience with the Docker setup. The MariaDB Docker should not phone home, or whatever it was doing at 20 mbit/s.
