The invention discloses an NAT traversal method and a server and belongs to the network technical field. The method comprises the following steps: receiving first request information sent by a client to a predetermined address; establishing a first connection with the client based on the first request information; receiving second request information sent by the client through the first connection; establishing a second connection with a communication opposite end based on the second request information; and transmitting data packages between the client and the communication opposite end based on the first connection and the second connection. According to the NAT traversal method and the server, the problems that, in the prior art, when new types of NAT devices appear, a STUN server cannot detect the types of the NAT devices or the reliability of the detected types of the NAT devices is not high, so that the client cannot realize NAT traversal, and furthermore, the adaptability of the conventional scheme is
