Configuration

After installing Tailscale, the next step is to configure it according to your needs. Here’s how you can do it:

Basic Configuration

1. Open the Tailscale admin console from your browser by visiting Tailscale Admin Console.
2. In the admin console, you can see all the devices connected to your network. You can also manage access controls and settings.
3. To configure access control lists (ACLs), edit the acl.json file in the admin console. For example:

   {
     "groups": {
       "group:admins": ["user@example.com"]
     },
     "acls": [
       {
         "action": "accept",
         "src": ["group:admins"],
         "dst": ["*:*"]
       }
     ]
   }

The above configuration allows users in the ‘admins’ group to access all devices on the network.

Advanced Configuration

For advanced users looking to customize their setup, Tailscale offers several options:

• Subnet Routes: Enable subnet routes to allow devices on your Tailscale network to access other devices on your local network. This can be configured in the admin console.
• Exit Nodes: Use an exit node to route internet traffic through a specific device on your Tailscale network. This can be useful for accessing geo-restricted content or improving privacy.

For more detailed configuration options, refer to the Tailscale Knowledge Base.

Advanced Tips

For those looking to get the most out of Tailscale, here are some advanced tips:

Using Subnet Routes

To enable subnet routes, you need to configure your Tailscale settings. This allows devices on your Tailscale network to access your local network. Here’s how:

sudo tailscale up --advertise-routes=192.168.1.0/24

This command advertises the 192.168.1.0/24 subnet to your Tailscale network, allowing other devices to access it.

Setting Up Exit Nodes

To set up an exit node, follow these steps:

1. Choose a device to act as the exit node and run the following command:

   sudo tailscale up --advertise-exit-node

2. On other devices, configure them to use the exit node:

   sudo tailscale up --exit-node=DEVICE_IP

This setup routes all internet traffic through the chosen exit node, enhancing privacy and allowing access to geo-restricted content.

Common Issues/Troubleshooting

Here are some common issues users may encounter and how to troubleshoot them:

1. Installation Errors: If you encounter errors during installation, ensure your system meets the minimum requirements and that you have the necessary permissions.
2. Connection Issues: If devices are not connecting, verify that the Tailscale service is running on both devices and that they are properly authorized in the admin console.
3. Network Access Problems: If you’re having trouble accessing local network resources, check your subnet routes and ensure they are correctly configured.
