Anybody Using Nebula?

After a very enlightening discussion in a previous thread, I decided to plunge into a mesh type network to connect my various servers and devices.

Nebula has been fairly straight forward to set up so far, but I’m having some trouble with the details and am curious if anybody has successfully got Nebula up and running for their network.

Installation on Linux platforms has been a breeze. Windows I can’t seem to get working. I was able to install but the service refuses to start. Can’t find any documentation besides random GitHub issue threads. MacOS was easy to install but having issues due to a VPN that’s running already.

I use a VPN because I travel a lot. I also use my MacBook to SSH into my servers or access remote file storage. My previous network configuration was connecting via wireguard to my network. I was able to do this while maintaining an always on VPN with the mullvad app. With Nebula that VPN seems to muck things up.

I’m also curious if anybody has had experience setting up a dual config for Nextcloud. Essentially accessing a Nextcloud server from nebula with a trusted device while still allowing public access for things list public shared links.

I got a small network running with Linux, android and Windows, but seldom use it. Windows install worked fine, but it remember it was not well documented (needed to use some argument for it to setup the service). Don’t use nextcloud but I do have vaultwarden working over it.

I’m planning to move to headscale due to the certificate management overhead.

I’m using nebula to remotely access the raspberry pi in my home network and it mostly just works. The dual setup for nextcloud might be a bit more tricky, at least if you want to use HTTPS. You’ll probably have to set up a reverse proxy in Nginx for at least one of the routes, since they need different certificates (although since Nebula already authenticates and encrypts your traffic, HTTPS is probably not necessary there).

I’ve not seen nebula, that looks a lot like tinc. Iight have to see how hard nebula is to get running.

If your looking for a mesh VPN, tinc is very easy to setup

Yes, have it running and it works well. Nextcloud setup is sth that I will still have to set up but the only problem I see there is certificates. To debug Nebula, simply try executing it by hand, e.g. nebula --config /path/config.yml and see what the error message is. Or check your journalctl of course. Share the message here and we can have a look!

What is nebula?

    But also self-hosted (the central server, i.e. “lighthouse”) and open-source

    There is a demand, and there is a supply. Decentralization trends lead more and more people to self-host, and you can’t get around it any other way.

    Self-hosting is essential for many commercial uses. You don’t want your critical infrastructure to rely on a third party which might or might not meet all regulatory requirements in your industry.

    Maybe you mean that but that is not what software means when they advertise self-hosting on their website.

    I wouldn’t call it a clone, Tailscale didn’t invent mesh VPN’s. I believe Nebula is fully self hosted, while Tailscale makes initial connections through their servers. That means Nebula is more secure and private if you’re paranoid, but also harder to set up. They’re also based on different VPN protocols.

    Tailscale actually published a surprisingly unbiased comparison: tailscale.com/compare/nebula

    daed ,

    Should probably be pointed out (and I assume the tailscale link does), but Tailscale offers a fully self-hosted option called Headscale also

    pluja ,

    Tailscale does not offer this. It is a community project. Headscale is not official.

    EncryptKeeper ,

    Given that Nebula is older than Tailscale, and was inspired by tinc, it’d be more accurate to say that Tailscale is the clone.
