## Introduction


## VPN Setup

The VPN Survice I use the ==Zerotier==. It is free and friendly to setup, so it is satisfy to initial Setup.

* https://www.zerotier.com

1. Sign up
2. Create a Network

After creating Network you will into the dashboard and see the Network ID.
You can modify the Name and add the description also choose the Access Control private or public. In my case I select private.

Choose the IP address.
Because free version is limit of 50 connects and one `*` mean 0~255 so I just need one star. For the reason I select the `192.168.195.*`.
