How to make my server reachable - eviltoast

Hello all,

I have started experimenting again with a local server and I am facing a few issues, here is my case.

I run Debian o an old HP prebuilt without GUI. I do everything with ssh from my laptop (basic connection ssh user@addr)

I have installed docker. I have installed a few containers. I also installed portainer for easier management.

All good so far because everything is local.

I have purchased a domain with cloudflare and set up a tunnel as to avoid exposing any ports and having an easier time managing and deploying stuff.

I have set up jellyfin and vaultwarden but when I tried to install nextcloud AIO it was advised to add a local reverse proxy as to avoid many problems.

My questions are:

Is the tunnel solution appropriate for jellyfin?

I suppose it’s OK for vaultwarden as there isnt much data being transfered?

Would it be better to run nginx proxy manager for everything or can I run both of the solutions?

Any general recommendations on the above and in general are appreciated!
