Someone here brought up that they were able to replace Cloudflare Tunnels with Tailscale - I can't seem to find the post, as it was a comment and deeply buried in a thread I've since forgotten the title of. :)
Can anyone explain the process for doing this? I assume it's through the use of their Funnel? I have three primary services I require to be accessible through Authentik (that's one of them) via my domain name.
EDIT
To answer the question of why I want to leave Cloudflare Tunnels - is basically that I have several services behind it (I forgot one so make that 4 I wish to have exposed). Two password managers, Psono for my special needs daughter which finds it easier than Bitwarden and Vaultwarden for myself and my work logins. So, I can't just set up a VPN or Tailscale at work to connect my work passwords to. :) I also have Authentik and Home Assistant tunneled at present. That doesn't explain the reason why though so let me start here:
My step-daughter is learning video production and editing, we don't want to share her videos on Youtube or other sites, but would like to keep it more local to home. With that said, Cloudflare may not notice it at first, bit it's against their TOS to stream videos, not to mention their just over 100mb cap for file xfers which leads me to the next reason. Early in May of this year, we were in an auto accident, and we are frequently sending forms, accident photos and paperwork etc to the Attorneys, I want to have control of the ownership of the files and would prefer not to email them, but link them to my server, frequently, those files even zipped can be over 100mb.
I do have a private DDNS provider I have my domain CNAME pointed to so it resolves to the home IP that way, so the ultimate plan is to untie my site from Cloudflare's DNS to a offload to a VPS or two for (NS1 and NS2) With a recent issue with Oracle Cloud, I'm not motivated to use them for this basic purpose.
And just a small part of me is starting to get tin hat against the idea that Cloudflare can decrypt the data before it hits my site before it encrypts it. Just just isn't sitting well with me at the moment. I can't verify this data yet, but I like to play it safe than sorry.

So, I ran a funnel test and yes it works, but still have to use the ts.net like others said, so at best, I can figure this to be a good backup service. I can't forward a CNAME to my TS DNS. I checked /r/tailscale (Duckduckgo sent me there), and about a month ago, someone asked if you could use your own domain, the answer was "not yet" but there seems to be some interest.
What I found pretty fascinating is the mobile app does work quite well on Android and is so far so good, I can at least feel better knowing that the phones are on WG full time now through Tailscale. I had issues with the official WG client and another one staying on with our phones full time, so this so far has been a good improvement.
I have been using Tailscale, connected it to my domain, I use Authentik for my OIDC/SSO Sign in and tied it that way for the MFA OIDC Login Tailscale let's you use. All I needed to do is setup a webfinger for it and once it verified my domain, I was able to give them my OIDC settings for them. Tailscale so far for me in the last year or so has been quite simple to use. Plus, being able to log into my admin console and any devices I enroll through Authentik's front end, has given me peace of mind knowing it's quite secure. (All of this on a Proxmox server BTW).
One may argue about self hosting Wireguard and I agree, it's quite easy to do if you use something like wg-easy which makes it simple to add phones to your network. My concern with it though was having to poke a hole into my firewall for the WG traffic to hit the server, once I got into Tailscale, it's made it easier and I don't have any open ports on the router now. I think this is primarily why the Jupiter Broadcasting guys push it so much on their podcasts, not to mention one of the hosts on his podcast is an employee for Tailscale as well, so that probably helps a bit.
As for funding for both Nebula, or Tailscale, they do cater to enterprise customers so you have the assurance that they do have to answer to them if they revoke a service or ruin it. :)
For Tailscale, it's just a matter of them allowing you to add 100 devices for free and it's simple command to install it on any client via the cli including Apple TV for example. For phones, I have Tailscale on my phone connected 24/7 to my exit node which is my Proxmox server which acts as one, and as a backup, my Raspberry Pi which acts as one as well. So, even if I'm on the road or away from home, I'm always on my home network (unless blocked by overzealous sysadmins on their public WiFi networks). There's not much to manage via the phone, but I like to think it's 'set and forget' really, once you have it all configured, it just runs in the background and they do not decrypt your traffic much less care what goes through it.
