Subnet routers act as a gateway, relaying traffic from your Tailscale network onto your physical subnet. In these cases, you can set up a “subnet router” (previously called a relay node or relaynode) to access these devices from Tailscale. When incrementally deploying Tailscale (eg.When connecting large quantities of devices, like an entire AWS VPC.With embedded devices, like printers, which don’t run external software.However, in some situations, you can’t or don’t want to install Tailscale on each device: That way, traffic is end-to-end encrypted, and no configuration is needed to move machines between physical locations.

Tailscale works best when the client app is installed directly on every client, server, and VM in your organization.
