3proxy is a lightweight, configurable proxy server for routing traffic between clients and network services. It combines several proxy protocols within a single application, allowing administrators to manage different types of connections without deploying separate proxy servers.
The software can provide controlled access to external network resources or allow clients to reach services through intermediary servers. It supports direct connections as well as more complex arrangements involving multiple proxies and different network protocols.
Configuration is handled through text files, with options for managing individual services, controlling access and defining how traffic should be forwarded. This makes 3proxy suitable for small network gateways, dedicated proxy servers and environments requiring detailed control over network connections.
This is free and open source software.
