Wonder how this compares to wireguard. Been thinking about https://github.com/juanfont/headscale

🤯That is super cool! Is there a good comparison between this and WireGuard from a security perspective? I know Cloudflare is moving away from WireGuard and implementing MASQUE which uses HTTP/3+QUIC. Wonderful to see multiple attempts at this, interested to see what gets the adoption.
this sounds a lot like part of how cloudflares tunnel works. me like!
I never used CF tunnels, but from the descriptions I read, it seem to serve a very different purpose. Yggdrasil will just connect your server to an overlay network that's fully encrypted (but public). If you expose services over Yggdrasil, your server will be directly exposed on the network, you just get full encryption as a bonus. Cloudfare on the other hand will "shift" your server access to their own server, and redirect traffic internally to your server over a secure channel. This means that your server is not publicly accessible.
Not quite true, I use cloudflared daily, its simply a daemon that connects back to CF. The daemon is configured on the CF side to proxy various local network (class C) URIs. I usually toss the daemon in the private network with the containers. The machines themselves still work fine over normal internet, the daemon does not cut a system off it simply provides proxy forward services.
This sounds very similar but without the configurability, just whatever I toss on the line I get. Which for the cases im thinking (replacing VPNs as suggested here) it will be great.
Ok thanks for the clarification (I've never used CF). Yggdrasil doesn't act as a proxy at all though so it's quite different. It simply creates a virtual interface on your host, and whatever comes in or get out of this interface is encrypted by default. Also, this interface can only access and be accessed over the Yggdrasil network.
its just attached at a different network layer. this would show up as an adapter on the machine i suspect.
Doesn't seem like a direct replacement. A VPN will anonymize you when connecting via regular protocols. This is kind of its own protocol. If your intended destination doesn't use Yggdrasil then you can't talk to them. Do I have that right? Not saying it's bad, it's just not equivalent.
VPN per sé is a connection between 2 points (Virtual Private Network) so that the remote host can be reachable with a private IP and doesn't meet this be public;, what you're talking about is VPN services (ProtonVPN, NordVPN, etc.) that are used to bypass Internet blocks and makes you appear as you are accessing Internet from a different location.
This is a cleaner way of presenting it, and more proprietary in nature versus the standard RFCs.
Does this require a static IP address? Can it be easily used when all nodes are behind a NAT with dynamic IP addresses?
No static IP required ! I use it on my phone over LTE and it works great. Same goes for the NAT, I use it at work to where my laptop sits behind a NAT and I don't have any issue.
From my understanding by reading the website, if non of your devices have a static IPv6 address, you need to add a public node or get a VPS that has static IPv6 address, is that true?
Thanks for sharing. I recall hearing about this before. After reading this thread I've been trying to vend some of my selfhosted apps over yggdrasil. The documentation is difficult to find. A good tutorial would be really useful. Here are my two biggest ~~stumbling blocks~~ headaches:
- ipv6 headache: I had to update my server host binding from
0.0.0.0to::(from ipv4 to ipv6). Apparently ipv4 still works but now ipv6 also works. This was the biggest blocker for me gaining access to my apps over yggdrasil using ipv6. - yggdrasil.conf headache: ipv6 syntax issues (apparently I need to learn me some ipv6 stuff) You need to put ipv6 ip addresses in brackets. This is an excerpt from my Listen attribute in my yggdrasil.conf file.
# Listen addresses for incoming connections. You will need to add
# listeners in order to accept incoming peerings from non-local nodes.
# Multicast peer discovery will work regardless of any listeners set
# here. Each listener should be specified in URI format as above, e.g.
# tls://0.0.0.0:0 or tls://[::]:0 to listen on all interfaces.
Listen: [
tls://[::]:8000
tls://[::]:8080
]
I also downloaded an yggdrasil vpn app for Android and was able to access both apps with Android after adding a peer connection in the settings. Later, I added my Android public key to the AllowedPublicKeys to lock down my apps to be only accessible to my client.
Thanks @wgs for the tip! 🏆
