Overview

This post summarizes the differences between Forward Proxy, Reverse Proxy, and Gateway servers.

What is a Forward Proxy Server?

A server that is placed between the client and server, acting as an intermediary for their communication (relay). It proxies requests from the client.

Client → Proxy Server → Internet → Server

The benefits include:

Log acquisition
Caching
Virus protection
Filtering (Access control)
Ensuring anonymity

What is a Reverse Proxy Server?

A server that is placed between the client and server, acting as an intermediary for their communication (relay). It proxies requests from the server.

Client → Internet → Reverse Proxy → Server

The benefits include:

Log acquisition
Caching
Virus protection
Load balancing
SSL offloading
Protection against unauthorized access

What is a Gateway Server?

A server that is placed between the client and server, relaying and controlling the conversion of networks and protocols.

The difference from Forward Proxy and Reverse Proxy is that a proxy acts as an intermediary for communication, while a gateway establishes the communication.
