# OpenWrt

[Sinip](https://sinip.tech) enables you to remotely manage **OpenWrt** devices that don't have a public IP address.

## Pre-requisites

To remotely manage your *OpenWrt* devices you'll need:

* One or more OpenWrt devices to be used as `Remote Devices`
* A PC or Smartphone to be used as `Admin Device`
* A *key* (file with .ovpn extension) downloaded from you [Sinip account](https://my.sinip.tech)

{% hint style="danger" %}
Remember: *key* files allow you to connect devices to your *Sinip* network, don't give them to anyone!
{% endhint %}

The *OpenWrt* firmware supports various network devices like:

* TP-Link
* D-Link
* Linksys
* MikroTik
* Ubiquiti
* Netgear
* TRENDnet
* Asus
* Xiomi

And many other brands, here is an exhaustive list: <https://openwrt.org/toh/start>

To install *OpenWrt* on your devices follow the official documentation: <https://openwrt.org/docs/start>

## Connect an OpenWrt device to your Sinip network

Connect to its web interface using a web browser (the default local IP address is `192.168.1.1`). Login as the `root` user.

Go to `System` -> `Software` and click `Update lists`.

Use the "Filter" field to find and install these packages:

* luci-app-openvpn
* openvpn-easy-rsa
* openvpn-openssl

Logout and Login back again to refresh the interface.

Download an unused *key* from your [Sinip account](https://my.sinip.tech). Make sure that you're not currently using the same key in another device. Then, on the OpenWrt device's web interface, go to `VPN` -> `OpenVPN` and upload the *key* file on the `OVPN configuration file upload` section using the name "Sinip".

{% hint style="warning" %}
Each device must use a *key* that is not currently used by any other device in your *Sinip* network.
{% endhint %}

Check the `Enabled` box for the "Sinip" connection, click `start`, and then click `Save & Apply`.

If everything went well, the `Started` field of the "Sinip" connection will have a `yes` value.

{% hint style="success" %}
If the *"Started"* field is *"yes"*, your device is successfully connected to your *Sinip* network and ready to use!
{% endhint %}

## Remotely manage an OpenWrt device

Once your OpenWrt device is connected to you *Sinip* network, you can manage it from an admin PC or Smartphone using a web browser, just connect to its *Sinip* IP address.
