System and method for processing network address conversion preferable regulation

Abstract

The invention provides a system and a method of the network address conversion preferred rule conversion treatment, wherein the system includes an NAT matching inyoite interface configuration module for configurating the NAT namely the network address conversion matching inyoite interface rule, and performing the information synchronizntion and transmission to the NAT inyoite interface rule list module; an NAT inyoite interface rule list module, for recording the NAT inyoite interface rule list, and performing the list item organization, for providing the information to the NAT matching inyoite interface rule list module as the reference standard; an NAT matching inyoite interface rule operating module, matching to find the NAT conversion item on the received data package, using the information in the NAT inyoite interface rule list as the reference standard, if matching with the NAT inyoite interface rule, novel NAT conversion items are generated according to the data package and therule information, and conversion is performed according to the novel NAT conversion items.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a system mechanism for network address translation (NAT) to perform translation processing according to optimal rules when communicating between a private network and a public network in a network. Background technique [0002] With the rapid development of the Internet, the Internet has gradually become a part of people's daily life. The continuous development of network technology and the continuous increase of people's demand for the network have resulted in the continuous expansion of the network scale and the increasingly tight network IP address resources. And NAT (Network Address Translation) technology solves this problem very well. Its main method is to convert illegal private network addresses into legal public network IP addresses, and establish a distinction between public and private networks so that network resources are fully utilized. When users acc...

Problems solved by technology

[0004] The purpose of the present invention is to provide a system and method for network address translation optimization rule conversion, to solve the problem that the public network address cannot be effectively used in the prior art, and to realize the public network address when communicating between the private network and the public network. The use can be carried out according to the configuration of the network administrator
