Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

Visibility how? You don't need to open any ingress ports on the VPS instance unless you plan on reverse proxying something back to your client node. Your client visibility will be to any endpoint you connect to, and any DERP servers you get proxied through from Tailscale.
The way I understand it, there's 2 use cases for a VPN, with different concerns and providers:
Is Tailscale fit for the second? I thought not, as the exit node is not an anonymized VPN server but one of your own machines.
If you create little solar-powered micro computers and toss them onto the roof of a bunch of random businesses with public Wi-Fi, then run them as exit nodes then you could bounce your connection around through a random set.
I didn't come up with this, I think it was a plot point in some novel I read.
That's crazy and genius!
"I don't do cloud computing, I do solar computing"
Yes, OP understand that, which is why he is asking about security to the exit node on a Tailnet.
I'm sorry...I'm just asking all the stupid questions up front.
They're good questions. I wasn't being rhetorical 🤣
It's hard to know exactly where your concern about visibility lies, hence my question 😉
Nah, it's good. I do have a knack for asking silly, basic questions. I certainly don't have the networking prowess and certifications that some of the group here has, and I just want to be cautious, perhaps overly cautious when implementing what I have proposed. I know what an overlay vpn does, and I know what a traditional vpn like say, PIA, does. I just want to proceed with caution because the end use has serious implications if improperly deployed. At the very least I want to make myself confidant that I have covered all bases.
Well if it demystifies Tailscale a bit, just think of it like a traditional VPN with specific controls over the traffic flow. It's e2e encrypted between every node, and you control the exit node. You're use-case would work just like OpenVON, for example, where your client traffic exits where you decide (your VPS).
If you really want a deeper understanding, have a looke at Headscale and maybe set it up on your VPS. You use your same Tailscale client, and just register it with the Headscale instance on your VPS. Just setting it up will give you a tutorial on how Tailscale works in general. You can ping me with questions, or the Discord is really active and responsive.
