Squid Proxy with OpenVPN

Overview

This project sets up a Squid proxy server that routes traffic through an OpenVPN client. It allows you to route your traffic through a VPN for added privacy and security.

Prerequisites

• Docker
• Docker Compose
• An OpenVPN configuration file (client.ovpn) should be in the $project_root/local directory.

Usage

1. Place your OpenVPN configuration file (client.ovpn) in the $project_root/local directory. Note: The CONFIG_FILE environment variable specifies the OpenVPN configuration file to use (e.g., client.ovpn). If this variable is not set, the container will automatically select a random .conf or .ovpn file from the /config directory using the following command:

   config_file=$(find /config -name '*.conf' -o -name '*.ovpn' 2> /dev/null | sort | shuf -n 1)

   To unser this variable edit the docker-compose.yaml

2. Build and start the services:

   docker compose build   
   docker compose up -d

Usage

1. Set your proxy settings to http://localhost:3128.
2. Verify the proxy is working:

   curl --proxy http://localhost:3128 http://ifconfig.co

Troubleshooting

• Check the logs for the OpenVPN client and Squid:

  docker logs openvpn-client
  docker logs squid

use flag -f to monitor logs like this docker logs -f openvpn-client

• Ensure DNS resolution works inside the OpenVPN container:

  docker exec -it openvpn-client ping ifconfig.co

Stopping the Services

To stop the services, run: sh docker compose down
