For now my NAS it not really running anything (I want to have proper DNS/IDM before starting any other service and for storage I think I may go with owncloud ocis or nextcloud)

I am still using my ISP’s router, so the firewall rule is on the NAS (for now it is almost a do it all server), otherwise I would run the pihole on the router I think

Do you have any idea on how to do it ? Knowing that I am on opensuse

Thank you for the reply. It is exactly this

So, for nextcloud and automatic torrenting it should not be too bad to protect windows users ?

I don’t selfhost mail but I heard of stalwart

Just wanted to add that in my experience, Castlevania lord of shadows was unplayable due to graphical bugs on windows, but flawless through proton (that didn’t need any setup btw)
