   Yes, I know I could use google and I think all chinese know google. And in
china there is a more popular search technology ISP named baidu than google. I
only want to get some  resolution method. 
   The simplest method is to programe with socket. I receive the TCP packet and
send  it out with UDP packet. It is ok. But if i implement it by myself I think
the efficiency is a problem.
   Yesterday I communicate with my friends about this problem. They suggest the
tunnel proxy may be a good method. When I need to transform the TCP to UDP I could
encapsulate the UDP to the payload of TCP protocol. If I need to transfrom the UDP
to TCP I could encapsulate the TCP to the payload of UDP protocol. I think it is a
good suggestion.
   Because I have ever done some work about IPv6. In Ipv6 over IPv4 they use
tunnel 
   I don't like anyone to teach me how to code or programe and I only want to get
a solution. :)

  Thank you. In every textbook it tells us the TCP reliable but UDP is not even in
Chinese textbook. :)

   OpenVPN may be a good method. But I think it is too complex for my project. I
like the simple solution. 
   In the end. Thank you very much :)
   Best wishes.
