GS Proxy - TCP Proxy for Galileosky Devices

This project implements a TCP proxy server for forwarding traffic to various backend services.

Description

The proxy accepts TCP connections and forwards them to target servers.

Device Configuration

To configure your Galileosky device to use this proxy server:

Remote Configuration Server

Command format: REMOTECONFIGADDR server,port

Example:

Request: REMOTECONFIGADDR <your-proxy-ip>,9444
Response: REMOTECONFIGADDR=<your-proxy-ip>,9444

Firmware Update Server

Command format: UPGRADEIP server,port

Example:

Request: UPGRADEIP <your-proxy-ip>,32132
Response: UPGRADEIP=<your-proxy-ip>:32132

Note: Commands are available on 7x terminals with firmware 44.0 and higher.

Requirements

• Docker
• Docker Compose

Usage

Start the proxy

docker-compose up -d

Stop the proxy

docker-compose down

Restart the proxy

docker-compose restart

View logs

docker-compose logs -f tcp-proxy

Check status

docker-compose ps

Configuration

HAProxy configuration is located in haproxy.cfg. After changing the configuration, restart the container:

docker-compose restart
