有人做过UDP nat穿透的没，用QT实现，从一个局域网到两外一个局域网，我按照原理写，两个局域网中的电脑向一个公网IP发送请求，公网记住两个内网机子的外网IP和端口，然后一个像两外一个发请求，然后一个在想另外一个发请求，可以没实现？

I don't understand you, but QT is not Qt.

有人知道不为啥不？？？

IMHO, QT - may be Quality Time, QuickTime or other, but Qt - software framework. "Wikipedia":http://en.wikipedia.org/wiki/QT

my server has gotten clientA and clientB's LAN's ip and port ,now clientA send a message to clientB , server tell clientB to connecte clientA. clientB is start to connecte clientA, but both are not get message from each other.

bq. clientB to connecte clientA

UDP are can not establish connection, only send and receive messages. Maybe I did not understood you correctly
And are you can show problem code?
