Yeah, exactly. That’s what I was trying to convey with that comment as well. The only thing necessarily exposed is whatever you’re running on the only port(s) that the tunnel uses.

There are some things you could do relatively easily to have more peace of mind.

With Cloudflare Tunnel you’re at least only allowing port 80/443 to hit your server already. You could consider also configuring Cloudflare to block countries outside your own to limit exposure.

You’d definitely want to have SSL configured for your site, or better yet, have it (and your other services) run behind a proxy that supports SSL.

It is also typically pretty easy to implement fail2ban so that you can limit brute force attempts to login on any of your exposed services.

I guess lastly make sure you’ve got backups elsewhere of these photos and videos.
