How to Install Tailscale on pfSense and Configure it as an Exit Node.

If you’re looking to enhance your home network security while enjoying the flexibility of accessing your devices remotely, setting up Tailscale on your pfSense router as an exit node is an excellent option. Tailscale, a powerful mesh VPN solution, allows for secure and private connections between your devices, no matter where you are in the world. Pairing it with pfSense, a versatile open-source firewall and router software, takes your networking setup to the next level. In this guide, we’ll walk you through everything you need to know about configuring Tailscale on your pfSense router to use it as an exit node.

What is Tailscale, and Why Use It with pfSense?

Tailscale is a peer-to-peer VPN service built on the WireGuard protocol. It simplifies networking by enabling secure connections between devices with minimal configuration. It’s especially useful for accessing devices behind NATs or firewalls without needing to open ports or deal with complicated forwarding rules.

When combined with pfSense, Tailscale provides:

• Secure access to your home network from anywhere.
