Moved to misc. Yes, you missed something: the point :-) The idea is that the existence of this entire 'ultranet' is undetectable by even someone snooping all national traffic. So a TCP port 80 connection looks to the snooper _exactly_ like an HTTP connection handshake. Only the ISN and the source address mark the connection as 'ultra' and take it into a back room where it connects to the real network. If the snooper tries to connecto to that port they the same HTTP service that all the other muggles see. Ian
