I tried setting up two different distros

Would you mind telling what were the two distros you were trying to setup just for reference?

Out of curiosity, how can I know if it’s already the case?

No hardening will protect you from out of date software with serious security holes

Connecting to the NAS only via VPN won’t be enough?

Don’t make it available from internet. This will solve the issue.

Thanks, I’ve read this countless times but that’s basically half of the use I make from my NAS so no.

I’ll try to secure it and still use it from outside / Internet then.

If someone knows how to apply security updates to ancient NAS from the brand I’m interested. Sadly mine is out of the loop, I guess I’ll have to harden it like hell then

Hi mate, impressive work! I run linkding docker on a 2014 NAS, do you think it might be able to cope with your more advanced solution? If not I’ll keep a bookmark to use it on my next one, cheers
