使用samba4-server在使用OpenWrt固件的树莓派4B上搭建SMB文件共享服务。

服务端：OpenWrt v21.02.2

客户端：macOS Monterey 12.3

I want to make the devices in my local network could access the internet through proxy. There are two use cases for me:

1. Provide a proxy service in the local network. So an application could use the proxy setting to access the internet.
2. For the application that DOES NOT have the proxy setting or DOES NOT use the system proxy setting(e.g., Youtube on the Nintendo Switch), create a transparent proxy service for those applications.

Prerequisites: you have set up a proxy service in the server.

The article will only introduce the basic concept and the process about how to set up a service.

You should refer to the exact step on this page.

后端可以分为三层：Controller Layer, Service Layer, 以及Data Persistence Layer。
