WireGuard on Ubuntu 24.04 LTS

WireGuard VPN on Ubuntu 24.04 LTS for Azure Marketplace

WireGuard is the modern open-source VPN that delivers state-of-the-art cryptography with a fraction of the code of legacy VPNs, making it fast to audit and fast to run. This image ships WireGuard pre-installed, pre-configured, and hardened on Ubuntu 24.04 LTS, ready to accept VPN peers on first boot inside your Azure subscription.

Why this image: Standing up WireGuard on Azure without a managed service means more than a package install. You also generate the server keypair, write a valid wg0 configuration, enable IP forwarding, wire the interface to start on boot, and patch current Ubuntu CVEs. This image does all of that so your team ships a working VPN gateway without the manual configuration work.

Who this is for: Platform engineers providing secure remote access to private Azure networks. Teams who need a self-managed VPN gateway in their own Azure subscription. Operations teams connecting on-premises sites to Azure over an encrypted tunnel.

Target use cases:

• Secure remote access — give employees encrypted access to private Azure subnets without exposing services publicly
• Site-to-site connectivity — connect on-premises networks to Azure over a fast encrypted tunnel
• Bastion alternative — reach management interfaces of private VMs through a single hardened entry point
• Multi-cloud networking — link workloads across Azure and other environments with a lightweight VPN mesh

What is pre-installed and configured:

• WireGuard with kernel module — wireguard-tools installed from the Ubuntu noble repos; the kernel module ships with Ubuntu 24.04
• Server keypair and wg0 generated at first boot — keys are never baked into the image; listens on UDP port 51820
• IP forwarding enabled — configured at build time so the gateway routes peer traffic immediately
• Pre-publish checks — automated audit covering Trusted Launch, SSH key injection, walinuxagent, and cloud-init idempotency
• Trusted Launch ready — Gen2 image with vTPM and Secure Boot support per Microsoft requirements
• Azure Linux Agent pre-installed — custom-script extension, run-command, and managed identity work on first boot
• Monthly patch cadence — rebuilt from upstream Ubuntu and project security advisories within days of each release

Recommended deployment: Standard_B2s (2 vCPU, 4 GB RAM) for small peer counts. Standard_D2as_v5 (2 vCPU, 8 GB RAM) for higher throughput. Assign a Public IP and place the VM in a subnet that can route to your private workloads.

System requirements: Minimum 1 vCPU, 1 GB RAM. Gen2 VM. Open UDP 51820 inbound in your Network Security Group.

Azure integration: Azure Monitor Agent, Defender for Cloud, Azure Backup, and Update Manager extensions install without conflicts. Assign a Managed Identity to let your workloads retrieve secrets from Azure Key Vault without embedding credentials in configuration files.

Licensing: WireGuard is GNU GPL version 2 open-source software. No per-seat license or royalty required. Azure compute and storage rates plus a $0.09 per vCPU-hour software fee apply.
