This is a proxy server hosted by my virtual machine to route traffic through an VPN, as well as a jump proxy server on the host machine to route shared network traffic.

The primary motivation for creating this setup is that the eduroam network in France causes several issues:

• Eduroam blocks many CDNs used by Tencent and other Chinese network service providers.
• Eduroam restricts UDP ports 4500 and 500, which are required for establishing a VPN connection on the host machine.
• Eduroam employs forced transparent DNS to monitor and potentially intercept user privacy.

• Node.js installed on the virtual machine.
• VPN configured and active on the virtual machine.
• A local network connection between the host machine and the virtual machine (e.g., NAT or Bridged).

1. Clone or copy the proxy server files to your virtual machine.

   git clone https://github.com/SaturnTsen/http-proxy
   cd http-proxy
   

2. Install dependencies using npm:

   npm install

Before running the proxy server, you need to configure the constants for your environment. You can modify the constant.example.js file in the root directory and rename it to constant.js to set the necessary parameters.

To start the proxy server, run the following command in your terminal:

npm run serve

If you want to route shared network (e.g. Wi-Fi) traffic through the host machine to your proxy server, you can run the jump proxy server on the host machine.

npm run serve:jump-proxy

Install PM2 to manage the proxy server:

npm install -g pm2

Start and save the proxy server process:

pm2 start "path/to/the/http-proxy/src/proxy.js" --name http-proxy

Similarly, start and save the proxy server process:

pm2 start "path/to/the/http-proxy/src/jump-proxy.js" --name jump-proxy
