Updated Tailscale client for jailbroken Kindles adds SSH, proxy, and TUN modes
Key points
- Tailscale SSH is now enabled by default.
- A new proxy mode allows apps like KOReader to reach other Tailscale nodes.
- Full TUN mode is available on some Kindles for device-level networking.
- The update improves Tailscale's utility on jailbroken Kindles.
Enhanced Tailscale Functionality on Kindle
An updated version of Mitanshu Sukhwani's Tailscale implementation for jailbroken Amazon Kindles has been released by open-source developers. This update brings several new capabilities to the device, improving its integration with Tailscale networks.
Previously, Tailscale on Kindle offered basic connectivity, allowing the device to appear on a tailnet and be reachable via its Tailscale IP. However, it lacked the ability for Kindle applications to route traffic through the Tailscale network.
Key New Features
The updated client now includes Tailscale SSH enabled by default, removing the need for USB networking SSH and its default credentials. A significant addition is the proxy mode, which enables applications such as KOReader to connect to other nodes within a tailnet, like Calibre/OPDS or Wallabag servers. Furthermore, a full TUN mode is now available on certain Kindle models, allowing for device-level Tailscale networking.
Addressing Routing Limitations
The previous Tailscale client on jailbroken Kindles typically operated in userspace mode, preventing it from utilizing the device's network routing layer (TUN mode). This meant applications could not directly access other Tailscale devices. For example, KOReader attempting to reach a Calibre server on a Tailscale IP would fail because the Kindle's operating system lacked the necessary routing information.
How Proxy Mode Works
The new proxy mode, facilitated by an update to the Kindle KUAL app by greywolf1499, resolves these routing issues. Users can start Tailscale in proxy mode and configure apps like KOReader to connect to a local proxy at 127.0.0.1:1055. The Tailscale daemon, listening on this port, then routes the connection through the Tailscale network, enabling communication between the Kindle and other Tailscale-connected devices.

Open-source developers have released an updated Tailscale client for jailbroken Amazon Kindles, introducing features like Tailscale SSH by default, a proxy mode for applications, and a full TUN mode for device-level networking on some models. This update significantly enhances the functionality of Tailscale on these unofficial devices, allowing apps to connect to other Tailscale nodes directly.
