How to disable open ports on TrueNAS Scale - and keep it persistent

[tomtom85]

Hello everyone,

(Linux noob warning)
I'm wondering if there's an easy way to disable port 111 on TrueNAS Scale, and keep the setting persistent?
Please share all steps as my knowledge of Linux CLI is close to zero, unfortunatelly.

No, there isn't. It is expected that you are using the NAS on a reasonably secure network, as there are literally hundreds of ways to attack and subvert services running on a local area network. If your use case requires more security, put the machines in question, including the NAS, behind a firewall such as an OPNsense firewall host.
