Tailscale Funnel · Tailscale Docs

Tailscale Funnel is currently in beta. To try it, follow the steps below to enable it for your network using Tailscale v1.38.3 or later. Tailscale Funnel lets you route traffic from the broader internet to a local service running on a device in your Tailscale network (known as a tailnet). You can use it to share a local service, like a web app, for anyone to access—even if they don’t use Tailscale
