WireGuard is the VPN protocol itself. It is fast, lightweight, and much simpler than older VPN options like OpenVPN. You can run WireGuard on pfSense, OPNsense, a Raspberry Pi, Linux, UniFi gateways, and many other platforms. The main advantage of WireGuard is control. You manage the server, the keys, the peers, the firewall rules, and the routing yourself. That gives you more flexibility, but it also means you are responsible for configuring everything correctly. I like WireGuard when I’m already managing a firewall or server that supports it. For example, if you already run pfSense, OPNsense

For most home lab users, I would set up both if possible. Use a split tunnel VPN when you are on a trusted network and only need access to internal services like a NAS, Proxmox server, Home Assistant, Blue Iris, UniFi, or a file share. Use a full tunnel VPN when you are on a network you do not trust and want all traffic routed through your home or business network. If you only want one configuration, this is how I’d decide: Use split tunnel if your main goal is remote access to internal devices. Use full tunnel if your main goal is securing traffic on public or untrusted Wi-Fi. Most people wh

Tailscale is a VPN service that uses WireGuard for the encrypted connections, but makes the setup much easier. Instead of manually creating WireGuard keys, configuring peers, opening firewall ports, and managing client configs, you install Tailscale, sign in, and your device joins your Tailnet. That is the main reason Tailscale is so popular. It removes a lot of the annoying parts of WireGuard setup. Tailscale is especially useful if you: Cannot port forward because of CGNAT or ISP limitations. Do not want to open ports on your router/firewall. Want an easy way to access devices across multi

For my own setups, I generally lean toward WireGuard when I want the VPN to be fully under my control and I’m already using a firewall or server that supports it. That is why I like WireGuard on pfSense, UniFi, OPNsense, or a Raspberry Pi. I would use Tailscale when I want remote access to work quickly, when port forwarding is not possible, when a device is behind CGNAT, or when I want easier multi-device management without manually building every peer relationship. Choose Tailscale if you want easy setup, no port forwarding, simple device management, CGNAT support, subnet routing, and exit no
