Abstract

The invention discloses a method for traversing NAT (Network Address Translation) equipment, comprising the following steps of: A, sending an NAT equipment type detection request by a client to acquire NAT equipment type information which corresponds to the client; B, initiating a conversation to a communication opposite end by the client to send the NAT equipment type information which corresponds to the client to the communication opposite end, and simultaneously acquiring the NAT equipment type information which corresponds to the communication opposite end; and C, traversing NAT equipmentby adopting corresponding modes by the client and the communication opposite end according to NAT equipment types which correspond to both parties. The invention actively sends the NAT equipment typedetection request through the client and adopts a corresponding traversing method aiming at the detected NAT equipment type which corresponds to the client, thereby realizing the traversing of the NAT equipment, meeting the real-time network application requirements of users inside enterprises and enhancing the network experience of the users.

Description

Methods of Traversing NAT Devices technical field The invention relates to the technical field of Internet communication, in particular to a method for traversing NAT equipment. Background technique At present, with the continuous increase of Internet users, the Internet Protocol Version 4 (IPv4) address resources used by the Internet are already very tight, and it is simply not enough for every user to have an IPv4 address that can directly access the Internet, that is, Public IP address. A large number of enterprise units only have a small number of public network IP addresses, so the enterprise can only use a large number of private network IP addresses that cannot directly access the Internet to meet the internal network communication needs of users in the enterprise. In order to allow users in the enterprise to use the Internet Enterprises generally use Network Address Translation (NAT) devices to convert private IP addresses within the enterprise into public IP addr...
