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).
-
No trolling.

Unencrypted HTTP can mean that anyone can see your traffic as it passes through their network. Your ISP will see that traffic. If you're streaming pirated music and you're in a country that cares about those things, might not go very well. From a security stand point though, you still wouldn't want to trust the authentication on the open port. A vulnerability may exist that you don't know about. It's always better to keep them closed and add another layer or two between your home computer and the public.
Tailscale let's you tunnel into your home network without opening any ports, and it encrypts the traffic. Much safer way of doing it.
Thanks. I really appreciate the insight. I’ll start learning about tailscale as a priority.
Here you go friend, enjoy! 😁

Thanks again! Do I understand right that once I:
The machines will be able to see each other, but the machines can not be seen outside of the network of those machines?
Also, my Raspberry Pi is hosting some other publicly exposed services that need to remain that way. Will tail scale take over those too?
I found a nice overview video here for anyone who might want it: https://invidious.nerdvpn.de/watch?v=Kzyolu9yn0E
It shouldn't mess with your current routing but if you're running other VPNs you may run into issues.
After you join the machines to the tailnet, each machine gets a new IP address ( only visible to other machines in the tailnet), by default it's a 100.x.y.z you can check the tailnet for the device IP.
Now you can keep the port closed on your router and it will still be accessible over the usual lan ip and port. But when you want to access remotely, turn on tailscale and connect using the tailnet IP.
Another cool thing you can do with this setup is turn your home server into an exit node. By default it will only route things that are in the tailnet (100.x.y.z subnet). But if you turn your home server into an exit node you can funnel all your traffic back through the exit node. Instant free VPN back home!
That sounds promising, thanks! You say LAN, but I can share this with people over the internet too, right?
