Multiproxy is a high-performance TCP proxy server capable to run multiple proxies at the same time. Supports up to 1023 proxies and 1024 active connections (configured in source code). It's a single-threaded and single-process application using epoll() for non-blocking and edge-triggered operations.
It can proxy any TCP traffic including TLS and file transferring (e.g. scp, ssh).
