I didn’t realize how overwhelming this would be, the amount of information is incredible.

Speaking from experience, it was quite overwhelming to me at first as well. It took me a handful of tries to wrap my head around Cloudflare Tunnels/Zero Trust. I persisted tho, and succeeded. It doesn’t help much that Cloudflare keeps rearranging their site, making it difficult to find necessary information. I will say, that when I migrated to a new server recently, it was a snap and everything clicked in place. There was no need to set up anything on their side. As I remember, it was a matter of a one liner code sequence they provided, to install the necessary components on my server. Jack’s a doughnut, Bob’s your uncle.
