What is GOST - GO Simple Tunnel?

GOST (GO Simple Tunnel) is a simple yet powerful security tunnel written in Golang. It is designed to establish secure connections between clients and servers, allowing for secure data transmission over untrusted networks. GOST supports multiple protocols and provides a range of features that make it a versatile tool for securing network communications.

GOST can be used as a standalone proxy server or as a tool for building secure tunnels between networks. It supports various protocols such as HTTP, HTTPS, HTTP2, SOCKS4, SOCKS5, and Shadowsocks. GOST also provides additional features like multi-level forward proxy, protocol conversion, traffic routing, and more.

Key Features

GOST offers a wide range of features that make it a powerful tool for securing network communications. Some of the key features include:

  • Support for multiple protocols: HTTP, HTTPS, HTTP2, SOCKS4(A), SOCKS5, Shadowsocks

  • Multi-level forward proxy with proxy chain support

  • Tunnel UDP over TCP

  • TCP/UDP transparent proxy

  • Local/remote TCP/UDP port forwarding

  • Intelligent routing control

  • DNS resolver and proxy

  • TUN/TAP device support

  • Proxy protocol conversion

  • Reverse proxy and intranet penetration

  • Dynamically adding data channel to existing services

These features allow GOST to handle various scenarios and provide flexible options for securing network traffic.

Who Should Use GOST - GO Simple Tunnel?

GOST is suitable for a wide range of users who need to secure their network communications. Some common use cases include:

  • Developers and system administrators who need to set up secure tunnels between networks

  • Users who want to bypass network restrictions and access blocked content

  • Organizations that need to secure their internal network communications

  • Individuals who value privacy and want to protect their online activities from surveillance

  • Anyone who needs a lightweight and easy-to-use tool for establishing secure connections

Whether you are a network professional or a casual user, GOST provides a simple and effective way to secure your network traffic.

How Does GOST - GO Simple Tunnel Work?

GOST works by establishing secure tunnels between clients and servers. It acts as an intermediary, encrypting and forwarding traffic between the two endpoints. Here's a high-level overview of how GOST works:

  1. The client initiates a connection to the GOST server using one of the supported protocols (e.g., HTTP, SOCKS5, Shadowsocks).

  2. GOST authenticates the client's request and establishes a secure tunnel between the client and the server.

  3. The client sends data through the secure tunnel to the GOST server.

  4. GOST encrypts the data and forwards it to the destination server through the configured forwarding chain.

  5. The destination server responds, and GOST encrypts the response and sends it back to the client through the secure tunnel.

  6. The client receives the encrypted response, decrypts it, and processes the data.

GOST supports various configuration options and can be used in different modes, such as proxy mode, forwarding mode, or reverse proxy mode. It also allows for dynamic configuration and supports a plugin system for extending its functionality.

How to Get GOST - GO Simple Tunnel?

You can obtain GOST in several ways:

  1. Binary files: Pre-compiled binary files for different platforms are available on the GOST releases page.

  2. Docker image: You can pull the GOST Docker image using the following command:

  3. Homebrew (for macOS users): Install GOST using Homebrew with the following command:

  4. Ubuntu Snap: Install GOST on Ubuntu using the Snap package manager:

  5. Building from source: If you have Go installed, you can build GOST from the source code:

Choose the installation method that best suits your needs and follow the instructions to get GOST up and running on your system.

How to Use GOST - GO Simple Tunnel?

Using GOST is straightforward and can be done through the command line. Here are a few examples of how to use GOST:

  1. Starting an HTTP proxy server:

gost -L=:8080

This command starts a GOST server listening on port 8080 and creates an HTTP proxy. Clients can now connect to this proxy server to access resources.

2. Starting a SOCKS5 proxy server with authentication:

gost -L=socks5://user:pass@:1080

This command starts a SOCKS5 proxy server on port 1080 with username and password authentication. Clients need to provide the correct credentials to use this proxy.

3. Creating a local port forwarding tunnel:

gost -L=tcp://:2222/

This command creates a local port forwarding tunnel. It listens on the local port 2222 and forwards all traffic to This is useful for accessing remote services securely.

4. Creating a remote port forwarding tunnel:

gost -L=tcp://:2222/ -F=socks5://

This command creates a remote port forwarding tunnel. It listens on the local port 2222, forwards traffic to, and uses a SOCKS5 proxy at for the outgoing connection.

5. Using a forwarding chain:

gost -L=:8080 -F= -F=socks5://

This command creates a forwarding chain. It starts a server listening on port 8080, forwards traffic through an HTTP proxy at, and then through a SOCKS5 proxy at before reaching the destination.

These examples demonstrate some common use cases for GOST. You can customize the commands based on your specific requirements, such as changing the listening ports, proxy types, or forwarding destinations.

For more advanced configurations and options, refer to the GOST documentation at The documentation provides detailed information on the available flags, configuration files, and usage scenarios.

By leveraging the power and flexibility of GOST, you can easily set up secure tunnels, bypass network restrictions, and protect your network communications.

Bottom Line

GOST - GO Simple Tunnel is a powerful and versatile tool for securing network communications. Its simple design, extensive protocol support, and rich feature set make it an excellent choice for anyone looking to establish secure connections between networks.

Whether you are a developer, system administrator, or privacy-conscious user, GOST provides an easy-to-use solution for protecting your data and ensuring secure communication over untrusted networks. With its command-line interface and flexible configuration options, GOST can be easily integrated into existing network setups or used as a standalone tool.

If you value security, privacy, and simplicity, GOST - GO Simple Tunnel is definitely worth exploring. Its open-source nature and active development community ensure that it will continue to evolve and provide reliable security solutions for users worldwide.
