Secure Socket Funneling (SSF) is a cross-platform network tool and toolkit that multiplexes TCP and UDP traffic through a single TLS-encrypted tunnel to a remote host. It provides TCP/UDP port forwarding, local and remote SOCKS proxies, remote shell access, file copy, and a native relay protocol via standalone executables.

Use cases

• forward tcp and udp ports through a secure tls tunnel
• create a socks proxy over an encrypted connection
• get a remote shell without ssh
• tunnel udp traffic like dns or voip through a firewall
• relay traffic across multiple hops
• copy files between machines over an encrypted channel
• ssh alternative that runs on windows without admin rights

When to choose

• you need UDP port forwarding, which SSH lacks
• you want a standalone cross-platform tunneling tool with no installation or admin rights
• you need SOCKS proxies in both directions (client-to-server and server-to-client)
• you want to chain tunnels through relay circuits

When to avoid

• you need a mature, actively maintained tool - the last release was 2021
• you only need basic TCP forwarding, where SSH is simpler and more ubiquitous
• you need a full VPN with network-layer routing
• you require a well-audited license - the repository has no standard open-source license (NOASSERTION)
