Turkey is invading Rojava/Kurdistan right now. What a fucking double standard.

Systemd-haters would rather install MacOS than admit that systemd is not that bad.

Headscale is pretty straight forward to set up and easy to use. And there are multiple WebGUIs available to choose from, if you need. If you have any questions, let me know.

Yes I'm running it on Docker and therefore have the docker0 interface.

Are you sure Tailscale in Docker is creating a wg0 interface? Because I got a working connection between my smartphone and my home server and the home server is not showing any interface related to Tailscale?

    
default via 192.168.178.1 dev ens18 
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 
192.168.178.0/24 dev ens18 proto kernel scope link src 192.168.178.178 

  

I'm not sure the Docker container is even using a tailscale interface, because there is none on my VPS or my home server.

And how do I see whether I have a device at /dev/net/tun?

There is no tailscale0, but also not on my home server which also runs Tailscale and which I can access remotely using my Android. Could my existing Wireguard setup interfere with Tailscale?

So to confirm your behavior, you can tailscale ping each other fine and tailscale ping to the internal network. You cannot however ping from the OS to the remote internal network?

Exactly.

Have you checked your routing tables to make sure the tailscale client added the route properly?

How do I do this? I use Headscale and headscale routes list shows the following:

    
ID | Machine | Prefix           | Advertised | Enabled | Primary
1  | server  | 0.0.0.0/0        | false      | false   | -
2  | server  | ::/0             | false      | false   | -
3  | server  | 192.168.178.0/24 | true       | true    | true

  

Also have you checked your firewall rules? If you’re using ipfw or something, try just turning off iptables briefly and see if that lets you ping through.

I'm not using a firewall, but the VPS is hosted on Hetzner, which has a firewall. But I already allowed UDP port 41641 and 41641. The wg0 rule is from the Wireguard setup I want to replace using Tailscale.

Yes, both clients can tailscale ping each other and after doing so the status shows active; relay "ams".

Using tailcale ping 192.168.178.178 also works for some reason.

Not sure what to do with the output of netmap.

No, I'm not using ACLs.

Doesn't seem to work.

Thanks, that's what I'm trying to do. :)

And my VPS doesn't have any IPs in the same range as my home server.

How do I make sure of this? What am I supposed to see using the command?

I'm using Headscale, but yes.

Of what?

VPS with public IPv4, Wireguard/Tailscale/Headscale and my own Domain.

Good for you, but this is the wrong sub for you then.

Is this as ad?

You could also use free LLMs, check out FMHY.

If you're using compression, try compsize.
