transparent socks proxy to tunnel tcp-traffic
"In this document, we'll access another machine's network internal DNS services (UDP port 53) with only SSH access to it. We will forward local UDP/53 traffic to TCP, then TCP traffic with the port-forwarding mechanism of SSH to the other machine, then TCP to UDP/53 on the other end."
"Tcpcrypt is a protocol that attempts to encrypt (almost) all of your network traffic. [...] Tcpcrypt is opportunistic encryption. If the other end speaks Tcpcrypt, then your traffic will be encrypted; otherwise it will be in clear text."
