ARC and Tailscale: Connect to RoonServer Without Port Forwarding

ARC and Tailscale: Connect to RoonServer Without Port Forwarding

ARC requires a connection back to your RoonServer in order to function and the vast majority of ARC users can satisfy this requirement through a straightforward network port forwarding setup. Unfortunately, port forwarding is not an option for some users, especially those with highly restrictive internet service providers or wireless carriers. While some blocked connections can be resolved through extensive tinkering or costly upgrades to ISP services there are still many Roon users who were effectively locked out of ARC.

We are pleased to announce that after diligent testing by Roon staff and the assistance of several Roon community volunteers, we have found a solution that is both free and easy to install which can immediately resolve many of these issues—Tailscale.

What is Tailscale?

Tailscale is a VPN service that makes the devices and applications you own accessible anywhere in the world, securely and effortlessly. Tailscale uses a technology called WireGuard to create private, encrypted subnetworks over the internet. This allows devices in separate locations with completely separate internet connections to reach one another as if they were on the same WiFi network. 

How does Tailscale Work?

Tailscale creates a secure tunnel between your devices without requiring manual port forwarding. This is particularly useful in environments with restricted network configurations, such as CG NAT, ever-changing IP addresses, and multiple layers of network routing (Double NAT).

What about Security?

Tailscale creates a secure tunnel based on WireGuard, an open-source VPN that is known for its elegant simplicity, strong encryption, and robust security. The connection through Tailscale does not expose your network to additional risks; instead, it actually fortifies the privacy and integrity of your data.

If you’d like to read more about what Tailscale is or how it works, please refer to their documentation:

Conditions Overcome by Tailscale:

  • CG-NAT issues due to ISP implementation
    This is a common practice with some major providers such as Vodafone Germany and Orange Group. Tailscale bypasses CG-NAT entirely.

  • Double-NAT scenarios
    If you have multiple active routers between your RoonServer and the internet, you have a complex network configuration that would require manual intervention. Tailscale can solve this problem without any intervention needed.

  • University/Corporate Networks (University WiFi, Government WiFi)
    Many university and corporate networks prohibit RoonServer from using the port forwarding required for ARC. Tailscale doesn’t require port forwarding and presents a workaround for these cases. 

  • Restrictive WiFi and Cellular Networks
    Public networks such as hotels, airports, cafes, or universities. In most cases, Tailscale will bypass downstream filtering that prevents ARC from properly connecting on heavily-managed public WiFi networks. 

Getting Started with Tailscale
Setting up Tailscale is straightforward. We will provide detailed guides and support to ensure you can seamlessly integrate Tailscale with your Roon ARC experience.

Tailscale Setup Guides

You will need to install Tailscale on both your RoonServer machine and your phone. Please see the appropriate guide for your Roon setup.
