Tailscale

Tailscale is a VPN solution that provides seamless connectivity between devices across different networks without the need for public IP addresses or complicated firewall rules.

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.

• 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.
