To enable button support, create the /etc/hotplug.d/button/00-button script, which can be found at openwrt.org/docs/guide-user/hardware/hardware.button#using_atheros_00-button_uci.

The WAN interface is configured as a DHCP client by default, making it easy to plug the router between an existing router and a computer. This allows both subnets and the Internet to be reachable simultaneously. Alternatively, the new router can be connected to a second physical interface if the computer has another one and routes correctly.

To preserve the config when updating the system, add /etc/hotplug.d/button/00-button as a line on http://192.168.8.1/cgi-bin/luci/admin/system/flash.

The Domino GUI is a great option for those who want a more user-friendly interface, especially if you plan to let others use your router.

It's much more intuitive and easier to navigate than LuCi, which can be overwhelming for some users.

The Domino GUI makes complex tasks simple with just a few clicks, whereas LuCi requires dozens of clicks to achieve the same result.

This is especially useful for those who need to configure settings quickly, like when you're on-the-go with a portable router.

Tying configuration settings to a physical switch on the router is also a convenient feature of the Domino GUI.

This can save you time and effort in the long run, especially if you're not a tech expert.

The wpad package is crucial for connecting to Eduroam, and upgrading it will ensure a smooth setup process.

After installing the full version of wpad, you'll need to access the web UI and click "Scan" on either WiFi interface. This will help the device identify available networks.

Select "Join network" for any "eduroam" connection/AP and enter your institution's configuration settings. Don't worry too much about the password for now, just submit the form.

Under "Wireless Security", select WPA2-EAP as the encryption method and set the remaining settings according to your institution's Eduroam configuration.

You can try using Tailscale as an exit node on your GL.iNet Mango, but it might not work as expected. The issue is that Tailscale doesn't cooperate with the Mango's routing by default.

If you try tailscale up --exit-node=seafile, it will cut off access to local clients connected to the Mango. However, you can add the --exit-node-allow-lan-access flag to restore local access.

But even with this flag, the Mango's local devices won't be able to pass traffic any farther than the Mango itself.

Tailscale is a modern VPN that integrates seamlessly with OpenWRT. It's a great alternative to traditional VPNs, which can be cumbersome to set up.

Tailscale uses WireGuard, a fast and secure VPN protocol, to establish secure connections between devices. This makes it ideal for remote access and networking.

One of the key benefits of Tailscale is its ease of use. It eliminates the need for complex VPN configurations, making it a great choice for those new to VPNs.

To set up OpenVPN as a client, start by installing the necessary packages, openvpn-openssl and luci-app-openvpn. Reboot and reload the web interface afterwards.

You'll also need to add the VPN's interface to the wan zone by running a specific command, uci add_list firewall.@zone[1].device="tun0"; uci commit firewall; /etc/init.d/firewall restart.

To configure the OpenVPN client, you'll need to get your client config file, a *.ovpn file. This file can be uploaded to the OpenWRT device through the web interface.

You can install Tailscale on your GL.iNet Mango router, which runs OpenWRT 19.

The Tailscale package is only 2.8 megabytes, which is a small size that fits on the Mango's stock firmware.

However, the GL.iNet firmware doesn't have Tailscale packages in its repositories, which can make installation tricky.

But, if you download the latest version of OpenWRT for your Mango from the OpenWRT site, you'll have enough room to install Tailscale and its packages will be available for installation.

The Mango's stock firmware has around 7 megabytes of free space, which is more than enough to install Tailscale.

To install Tailscale, you can follow the steps outlined in the example, which involves adding a line to the OpenWRT startup script.

This line will run the Tailscale startup script after a 15-second delay, which allows the script to unpack and configure Tailscale properly.

You can also use a USB drive to store your Tailscale configuration and packages, as described in the example.

This approach can be useful if you need to modify the Tailscale startup job without logging in to the Mango.

Here's a list of the steps to install Tailscale on your Mango:

Note that configuring Tailscale to use an exit node can be a bit tricky, as described in the example.

However, with the right configuration, you can use your Mango as an exit node to route traffic through a VPN.

To install OpenWrt on your GL.iNET device, start by checking the OpenWrt Table of Hardware to ensure your model is supported. Download the correct OpenWrt firmware build from their site.

The installation process is relatively straightforward. Download the "Firmware OpenWrt Upgrade" from the table and go to the router's internal updater page to upload the build image. Confirm the checksum and wait for the process to complete.

If you're using a GL.iNET GL-AR750 or GL-MT300N_V2, you can follow the steps below to flash OpenWrt:

Note that you may need to uncheck "keep settings" or reset to defaults after flashing, depending on your device and configuration.

First and foremost, check the OpenWrt Table of Hardware to ensure your device is supported.

To start, download the correct OpenWrt firmware build from their website.

Uploading the build image through the router's internal updater page is a straightforward process.

You'll then have full access to LuCI, the web UI, and SSH for deeper customization.

One of the benefits of OpenWrt is the ability to create split WiFi networks for yourself and guests.

OpenWrt is a custom, open-source Linux-based firmware for routers. It's a game-changer for anyone looking to unlock advanced features and customization options.

For those new to OpenWrt, it's essentially a replacement for the stock firmware that comes with your router. This upgrade offers a ton of benefits, including:

Having a full package manager is a major plus, allowing you to easily install and manage software just like on a real OS.

Two years ago, installing Tailscale on an OpenWRT router required manual installation, which is no longer the case thanks to the OpenWRT package manager.

I cheated and put the Tailscale binary on a USB flash drive when I set things up two years ago, which turned out to be a clever move.

Having the Tailscale configuration and keys on a USB drive provides a layer of security, as it can be easily removed if needed.

This setup also makes it easy to loan out the router to a friend, as they won't have access to the Tailscale configuration without the USB drive.

The convenience of the OpenWRT package manager is a game-changer, but it's also worth considering the potential benefits of a more manual setup.

In my case, not having to install Tailscale manually has been a blessing, but I'm also glad I didn't have to rely on the package manager from the start.
