The Windows Proxy Server is built to provide Android-side access to the extranet.

During this time, there is a situation where the mobile network is charged. But you can access the school's internal network, such as the school's official website library. So here I think of a way to use a host within the school to access the Internet to act as a proxy server (I use my own computer, not the server).

One, need the software:

PC-Side, Ccproxy

Android, proxydroid If you want to set up a global proxy, the phone needs to root the software's source address: https://github.com/madeye/proxydroid

Second, building the necessary conditions:

The PC that acts as a server can be a server with fixed IP (external network IP), and its own PC (intranet IP), which requires your networked device to be in the same network segment as the intranet host.

Third, software configuration

Simple configuration of CC proxy:

Download the free version and limit the number of connections to 3. But it's completely enough for your own use. After installing the software, click on the account to add the account. In the properties, select Allow section in the Allow range. Then click New "like:

Other defaults are available. For the full use of the software, you can search by yourself.
