The influence of NAT (network address translator) devices is analyzed,which are widely in existence,on P2P (peer-to-peer) communications. NAT-Traversal technologies are expatiated such as connection reversal and UDP hole punching,then a scheme based on these technologies is advanced and implemented. With the scheme,hosts behind NATs can found P2P communication sessions across NATs with the help of Medi-Server,then they can communicate directly. At last,some key problems in NAT-Traversal technologies are analyzed and explained.
