Hi Adrian,

I'm afraid you would have to implement such an element. The TCP protocol is
reasonably complex, and Click does not yet support it natively. However,
you could use a simple Click script to divert packets to a user-level
program, which would then encapsulate the packets in a TCP connection. We
have elements that would help you do that; look for the 'transparent
traffic diverter' in our OPENARCH paper or my thesis, and let us know if we
can help further.
