# Tailscale

By joining a Tailscale network, your router can function as a subnet router, enabling remote access to local resources or securely connecting multiple subnets.

## Example of Setting Tailscale

Navigate to the router menu: SYSTEM > Terminal. Enter the username root and log in with the password you set.

### 1. Install Tailscale

All commands are executed in the SYSTEM >Terminal section of the router menu.

```
opkg update
opkg install tailscale
```

### 2. Enable the ZeroTier

Enable and start the Tailscale service.

```
/etc/init.d/tailscale enable
/etc/init.d/tailscale start
```

### 3. **Authenticate and Join Network**

Use this command to authenticate your device:

```
tailscale up
```

This command will generate a URL. Open the URL in your browser and log in with your Tailscale account to authorize the device.

### 4. **Configure as Subnet Router (Optional)**

If you need to expose the local subnet through Tailscale, use:

```
tailscale up --advertise-routers=192.168.30.0/24 --accept-dns=false
```

Replace `192.168.30.0/24` with your local subnet.

Prevent Tailscale's DNS Settings from disrupting your local network.

### 5. Enable Subnet Routes in Admin Console

* Visit the [Tailscale Admin Console](https://login.tailscale.com/admin).
* Go to **Machines**, locate your router device, and turn on the **Subnet routes** option.

After completing the above settings, we can connect the remote device to the router and to the devices connected to it.
