Abstract

The invention discloses a Portal authentication method and system based on network address conversion 444 and relates to the technical field of information technology (IT) device authentication. Wlanuserip attributes are carried in a broadband remote access server (BRAS) redirection message and used for transferring private network Internet protocol (IP) attributes obtained by a user. When the user visits a Portal authentication webpage, the Portal can acquire a private network IP of the user. Due to the fact that a Portable platform builds a correlation between a BRAS device IP and a private network IP address pool when hot spots are built and opened, and the Portable authentication platform can determine an access device of the user through the user private network IP to achieve interaction between the Portal platform and the BRAS device and finish functions of authentication, offline and the like of the Portable user.

Description

technical field [0001] The present invention relates to the technical field of IT equipment authentication, in particular to a portal (Portal) authentication method and system based on Network Address Translation 444 (NetworkAddressTranslation444, NAT444). Background technique [0002] As the public IPv4 addresses are about to be exhausted, and the IPv6 technology has not yet matured for commercial use, NAT444 technology is recognized as one of the transitional technologies. [0003] The main idea of ​​the NAT444 solution is to improve the deployment position of NAT44. The operator deploys the carrier-grade NAT44 equipment CGN, and at the same time forms a two-level address translation with the user-side NAT to form three address spaces, namely, the user-side private address, the operator's private address, and the user-side NAT. public network address. This is also the origin of the name NAT444. The NAT444 solution can improve the reuse rate of IPv4 addresses, alleviate t...
