NetBird

NetBird is an open-source, WireGuard-based network overlay that connects servers and devices into a peer-to-peer private network. It does not require opening inbound ports or configuring firewall rules. All connections are initiated outbound. This image ships the NetBird client pre-installed, ready to join your network.

Software included

Component	Version
NetBird	0.71.4
Ubuntu	24.04 LTS

Getting started

1. Connect to your VM

ssh ubuntu@<your-vm-ip>

2. Join your NetBird network

You will need a setup key from your NetBird management console. Setup keys are created under Setup Keys in the NetBird dashboard.

With NetBird Cloud (app.netbird.io):

sudo netbird up --setup-key <your-setup-key>

With a self-hosted management server:

sudo netbird up \
  --management-url https://<your-management-server> \
  --setup-key <your-setup-key>

3. Verify the connection

netbird status

You should see the VM listed with its NetBird IP. Other peers in the same network will appear in the status output.

Managing NetBird

# Check connection status
netbird status

# Disconnect
sudo netbird down

# Reconnect
sudo netbird up

# View logs
sudo journalctl -u netbird -f

Security

NetBird uses WireGuard for encrypted peer-to-peer tunnels. All traffic between peers is encrypted end-to-end. UFW is enabled and allows SSH (port 22) only. No additional ports need to be opened for NetBird traffic.

Access control between peers is managed via policies in the NetBird management console.
