Since the STT protocol does not engage in the usual TCP 3-way handshake,
so it will have difficulty traversing stateful firewalls.
The protocol is documented at

+ https://tools.ietf.org/html/draft-davie-stt
- All traffic uses a default destination port of 7471. STT is only
- available in kernel datapath on kernel 3.5 or newer.
