I want to start with self hosting something available from internet. Currently I have jellyfin, nas etc but everything is available in local network.
My biggest concern is securing local network. I thought i will run application on separate server, I will use small vps as proxy, but Im not sure if it will be enough


I run my server on the internet, and my security is crowdsec + geo ip block (well, white-list my country’s ip but same idea) and authelia.
Using this setup, I barely ever have even bots randomly pingig me, let alone anyone trying to access my NAS.
