# Tailscale LOPOWER
|
|
|
|
"Little Opionated Proxy Over Wireguard-encrypted Routes"
|
|
|
|
**STATUS**: in-development alpha (as of 2024-11-03)
|
|
|
|
## Background
|
|
|
|
Some small devices such as ESP32 microcontrollers [support WireGuard](https://github.com/ciniml/WireGuard-ESP32-Arduino) but are too small to run Tailscale.
|
|
|
|
Tailscale LOPOWER is a proxy that you run nearby that bridges a low-power WireGuard-speaking device on one side to Tailscale on the other side. That way network traffic from the low-powered device never hits the network unencrypted but is still able to communicate to/from other Tailscale devices on your Tailnet.
|
|
|
|
## Features
|
|
|
|
* Runs separate Wireguard server with separate keys (unknown to the Tailscale control plane) that proxy on to Tailscale
|
|
* Outputs WireGuard-standard configuration to enrolls devices, including in QR code form.
|
|
* embeds `tsnet`, with an identity on which the device(s) behind the proxy appear on your Tailnet
|
|
* optional IPv4 support. IPv6 is always enabled, as it never conflicts with anything. But IPv4 (or CGNAT) might already be in use on your client's network.
|
|
* includes a DNS server (at `fd7a:115c:a1e0:9909::1` by default and optionally also at `10.90.0.1`) to serve both MagicDNS names as well as forwarding non-Tailscale DNS names onwards
|
|
* if IPv4 is disabled, MagicDNS `A` records are filtered out, and only `AAAA` records are served.
