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


Public server - Pixelfed ;)
I think Pixelfed can sit nicely behind a reverse proxy, to reduce exposure.
I don’t know if there are prebuilt scenarios for pixelfed in crowdsec or fail2ban but it shouldn’t be so hard to at least write something to prevent bruteforce.
