Community FAQ

Questions by product

Headscale FAQ

How complex is it to self-host Headscale compared to using the official Tailscale service?

Self-hosting Headscale requires moderate to advanced infrastructure knowledge, including managing a Linux server, setting up persistent storage for state, and configuring DNS and firewall rules. Unlike the official Tailscale service, you must handle updates, backups, and scaling yourself. While Headscale automates coordination for WireGuard meshes, it does not provide a managed UI or support, so operational overhead is higher.

Community insight informed by Reddit discussions

Does Headscale support offline or air-gapped environments where clients cannot reach an external coordination server?

Yes, Headscale is designed for self-hosted use and can operate entirely within an offline or air-gapped network as long as clients can reach the Headscale server. Since it implements the Tailscale coordination protocol locally, no external internet connectivity is required for client coordination or key distribution once the server is set up.

Community insight informed by Hacker News discussions

How does Headscale ensure data ownership and privacy compared to using Tailscale's cloud service?

Headscale stores all coordination metadata, authentication keys, and device information on your own infrastructure, giving you full control over data ownership and privacy. Unlike Tailscale's cloud service, no user or device data is sent to third-party servers, eliminating reliance on external trust boundaries and reducing exposure to data leaks or surveillance.

Community insight informed by Reddit discussions

Are there any API limitations or missing features in Headscale compared to the official Tailscale coordination server?

Headscale implements the core Tailscale coordination protocol but lacks some advanced features present in the official service, such as Magic DNS integration, ACL policy management UI, and certain device authorization workflows. The API surface is sufficient for basic client coordination, but some newer Tailscale features may not be supported or require manual configuration.

Community insight informed by StackOverflow discussions

Is there a straightforward migration or export path from Tailscale's official service to Headscale?

Currently, there is no automated migration tool to export device states or ACLs from Tailscale's cloud to Headscale. Users typically need to manually onboard devices to Headscale by generating new keys and re-authenticating clients. ACL policies must also be recreated manually. The community is actively discussing tooling improvements, but migration remains a manual process.

OpenVPN Access Server FAQ

How complex is the self-hosting and deployment process for OpenVPN Access Server compared to other VPN solutions?

OpenVPN Access Server requires a more traditional deployment approach involving installation on a dedicated server or VM, configuration of certificates, and network routing setup. Unlike modern mesh VPNs, it does not offer zero-config peer-to-peer connections, so initial setup and maintenance can be more complex and require networking expertise. However, its centralized web-based admin UI helps manage users and policies once deployed.

Community insight informed by Reddit discussions

Does OpenVPN Access Server support offline functionality or does it require constant internet connectivity?

OpenVPN Access Server itself does not require constant internet connectivity once the VPN server and clients are configured on the same network or connected via a routable link. However, for remote access scenarios, clients need internet access to reach the VPN server. The server can operate fully offline within a private network, but remote access use cases inherently depend on network connectivity.

Community insight informed by Hacker News discussions

Who owns the VPN session and user data when using OpenVPN Access Server, and how is data privacy handled?

With OpenVPN Access Server, all VPN session data and user credentials are stored locally on the self-hosted server under the enterprise's control. No user data is sent to third-party cloud providers by default. This ensures full data ownership and privacy as long as the server environment is secured and access is properly managed by the organization.

Community insight informed by StackOverflow discussions

Are there any API limitations or automation options available for managing OpenVPN Access Server users and policies?

OpenVPN Access Server provides a REST API and command-line tools for user and configuration management, but the API coverage is somewhat limited compared to fully cloud-native VPN solutions. Automation is possible but may require combining CLI scripts with API calls. The API primarily supports user management, session monitoring, and basic configuration tasks rather than full policy orchestration.

Community insight informed by Forums discussions

What are the recommended migration or export paths if we want to move from OpenVPN Access Server to another VPN solution?

OpenVPN Access Server allows exporting user certificates and configuration files, which can be used to migrate clients to other OpenVPN-compatible servers. However, there is no automated migration tool for policies or centralized settings, so these need to be manually recreated in the new system. Enterprises typically export user keys and reissue server configs when transitioning to alternative VPN platforms.
