* [client] Add WGConfigurer interface To allow Rosenpass to work both with kernel WireGuard via wgctrl (default behavior) and userspace WireGuard via IPC on Android/iOS using WGUSPConfigurer * [client] Remove Rosenpass debug logs * [client] Return simpler peer configuration in outputKey method ConfigureDevice, the method previously used in outputKey via wgClient to update the device's properties, is now defined in the WGConfigurer interface and implemented both in kernel_unix and usp configurers. PresharedKey datatype was also changed from boolean to [32]byte to compare it to the original NetBird PSK, so that Rosenpass may replace it with its own when necessary. * [client] Remove unused field * [client] Replace usage of WGConfigurer Replaced with preshared key setter interface, which only defines a method to set / update the preshared key. Logic has been migrated from rosenpass/netbird_handler to client/iface. * [client] Use same default peer keepalive value when setting preshared keys * [client] Store PresharedKeySetter iface in rosenpass manager To avoid no-op if SetInterface is called before generateConfig * [client] Add mutex usage in rosenpass netbird handler * [client] change implementation setting Rosenpass preshared key Instead of providing a method to configure a device (device/interface.go), it forwards the new parameters to the configurer (either kernel_unix.go / usp.go). This removes dependency on reading FullStats, and makes use of a common method (buildPresharedKeyConfig in configurer/common.go) to build a minimal WG config that only sets/updates the PSK. netbird_handler.go now keeps s list of initializedPeers to choose whether to set the value of "UpdateOnly" when calling iface.SetPresharedKey. * [client] Address possible race condition Between outputKey calls and peer removal; it checks again if the peer still exists in the peers map before inserting it in the initializedPeers map. * [client] Add psk Rosenpass-initialized check On client/internal/peer/conn.go, the presharedKey function would always return the current key set in wgConfig.presharedKey. This would eventually overwrite a key set by Rosenpass if the feature is active. The purpose here is to set a handler that will check if a given peer has its psk initialized by Rosenpass to skip updating the psk via updatePeer (since it calls presharedKey method in conn.go). * Add missing updateOnly flag setup for usp peers * Change common.go buildPresharedKeyConfig signature PeerKey datatype changed from string to wgTypes.Key. Callers are responsible for parsing a peer key with string datatype.

New: NetBird terraform provider
NetBird combines a configuration-free peer-to-peer private network and a centralized access control system in a single platform, making it easy to create secure private networks for your organization or home.
Connect. NetBird creates a WireGuard-based overlay network that automatically connects your machines over an encrypted tunnel, leaving behind the hassle of opening ports, complex firewall rules, VPN gateways, and so forth.
Secure. NetBird enables secure remote access by applying granular access policies while allowing you to manage them intuitively from a single place. Works universally on any infrastructure.

Quickstart with NetBird Cloud
- Download and install NetBird at https://app.netbird.io/install
- Follow the steps to sign-up with Google, Microsoft, GitHub or your email address.
- Check NetBird admin UI.
- Add more machines.
Quickstart with self-hosted NetBird
This is the quickest way to try self-hosted NetBird. It should take around 5 minutes to get started if you already have a public domain and a VM. Follow the Advanced guide with a custom identity provider for installations with different IDPs.
Infrastructure requirements:
- A Linux VM with at least 1CPU and 2GB of memory.
- The VM should be publicly accessible on TCP ports 80 and 443 and UDP port: 3478.
- Public domain name pointing to the VM.
Software requirements:
- Docker installed on the VM with the docker-compose plugin (Docker installation guide) or docker with docker-compose in version 2 or higher.
- jq installed. In most distributions
Usually available in the official repositories and can be installed with
sudo apt install jqorsudo yum install jq - curl installed.
Usually available in the official repositories and can be installed with
sudo apt install curlorsudo yum install curl
Steps
- Download and run the installation script:
export NETBIRD_DOMAIN=netbird.example.com; curl -fsSL https://github.com/netbirdio/netbird/releases/latest/download/getting-started.sh | bash
- Once finished, you can manage the resources via
docker-compose
A bit on NetBird internals
- Every machine in the network runs NetBird Agent (or Client) that manages WireGuard.
- Every agent connects to Management Service that holds network state, manages peer IPs, and distributes network updates to agents (peers).
- NetBird agent uses WebRTC ICE implemented in pion/ice library to discover connection candidates when establishing a peer-to-peer connection between machines.
- Connection candidates are discovered with the help of STUN servers.
- Agents negotiate a connection through Signal Service passing p2p encrypted messages with candidates.
- Sometimes the NAT traversal is unsuccessful due to strict NATs (e.g. mobile carrier-grade NAT) and a p2p connection isn't possible. When this occurs the system falls back to a relay server called TURN, and a secure WireGuard tunnel is established via the TURN server.
Coturn is the one that has been successfully used for STUN and TURN in NetBird setups.
See a complete architecture overview for details.
Community projects
Note: The main branch may be in an unstable or even broken state during development.
For stable versions, see releases.
Support acknowledgement
In November 2022, NetBird joined the StartUpSecure program sponsored by The Federal Ministry of Education and Research of The Federal Republic of Germany. Together with CISPA Helmholtz Center for Information Security NetBird brings the security best practices and simplicity to private networking.
Testimonials
We use open-source technologies like WireGuard®, Pion ICE (WebRTC), Coturn, and Rosenpass. We very much appreciate the work these guys are doing and we'd greatly appreciate if you could support them in any way (e.g., by giving a star or a contribution).
