Beginners question: Safety of VPN routing to Synology NAS

[DrGonzoNL]

I could use some confirmation from experts active on the forum.
Setup: Synology DSJ216 which is only open to local lan. Not setup for logging from outside sources

To use the NAS as a download station I followed the steps in https://forum.opnsense.org/index.php?topic=4979.15
Provided by Nilss. I also added my laptop to the vpn user group tot check if everything is setup alright with no DNS leaks.

Everything is routed nicely through my vpn provider via openvpn and the dns leak tests are good.

Now the question, when searching online I have came across people saying not to connect a NAS to a VPN connection. https://www.reddit.com/r/synology/comments/iaayq7/how_to_check_vpn_leak/

As far as I understand routing, there should not be an security issue bit the above linkade me doubt myself. Am I taking a risk I am not seeing?

Thanks for any help or guidance!

I have been monitoring my logs on the Synology and there is no extra activity found. I guess I am safe, so this topic can be deleted/closed
