Embodiment Construction

[0040] In view of the technical problems existing in the prior art, the present invention proposes a network protocol IP access method. In the web page-based access scenario (Portal), the core idea is not to allocate a valid public network IP before authentication. Only the private network IP is assigned for authentication, which is called the initial IP. The initial IP (authentication IP) is reserved in conjunction with DHCP during the online period of the user, and will not be distributed to other users. At the same time, on the premise of keeping the initial IP unchanged, the new IP (authorized IP) can be changed at will, so that after the public network IP is allocated, or when there are multiple public network IPs (such as IP and IPv6 dual stack), even the allocated public network When the IP is an IPv6 address, it can realize user-based original IP handshake check and offline processing.

[0041] Such as image 3 As shown, the method specifically includes the following...

Abstract

The invention discloses an IP access method. The IP access method includes the steps that an initial IP address used by a user device in the Portal authentication process is reserved through an access device after the user device passes Portal authentication, and is forbidden from being distributed to other user devices, then a new IP address is distributed to the user device when an IP address application request of the user device is received, and the corresponding relation between the new IP address and the initial IP address is saved. The access device and an authentication server can not need to perceive IP address changes of a user at any time, and the networking flexibility of NAS devices is greatly improved. The invention further discloses the access device.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a network protocol IP access method. The invention also relates to an access device. Background technique [0002] Such as figure 1 As shown, it is a schematic diagram of the composition of the Portal system in the prior art, wherein each device and its functions are as follows: [0003] Authentication client: the client system installed on the user terminal, which is a browser running (Hyper Text Transport Protocol, Hypertext Transfer Protocol) HTTP / (Hypertext Transfer Protocol Secure, Hypertext Transfer Protocol Secure) HTTPS protocol or running a Portal client software host. [0004] Access equipment: a general term for broadband access equipment such as switches and routers, which mainly have the following three functions: [0005] (1) Before authentication, all HTTP requests of the user are redirected to the Portal server; [0006] (2) During the authentication p...
