I mean, I am using CloudFlare to manage my outbound/inbound connections, at least though my domain name. I've been having some issues with people just poking at my Public IP for months now, and I really don't want to have to change my public IP. Even if they block access to my own printer, they aren't always remote, and I can easily get physical access to my machines whenever. They literally sit right next to me while I am at home.
See above; I will look into doing safe mode from CLI and check out that guide for Safe Remote Access. Nothing on the internet is safe. If need be, I will post any more issues and errors, in an attempt to help you guys squash vulnerabilities like this.
I've updated OctoPrint. Not much has changed. One of my instances is perfectly fine. One of my instances is bugged. I will change haproxy to point to the webcam, which will indeed break my abilities to upload directly from Slic3r and Cura, but I guess I will have to deal with that for now.
