Problems solved by technology

However, for devices that do not have client software installed or cannot be installed due to system configuration problems, such as mobile phone devices in the mobile network, after the user passes the authentication, there is no mechanism to trigger the release of the private network IP address that the client has obtained and Trigger the client to re-apply for a public network IP address, which will cause the client to be unable to apply for a public network IP address even if it passes the authentication, and cannot access more Internet resources

Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] The Portal secondary address authentication method provided by the present invention does not need to additionally load the Portal client software described in the background technology on the terminal, that is, in the case of no Portal client software, the Portal secondary address authentication is realized through DHCP and Portal linkage . The method provided by the invention is described below:

[0046] see figure 2 , figure 2The flow chart of the method provided by the embodiment of the present invention. This method is applied to a network access device with a DHCP relay (relay) function, that is, the network access device has a DHCP relay function on the one hand, and on the other hand, accesses a client and has the function of a...

Abstract

The invention provides a Portal secondary address authentication method and a Portal secondary address authentication device. The method is applied to network access equipment with a dynamic host configuration protocol (DHCP) relay function, and comprises the following steps that: the network access equipment intercepts a DHCP renewal message transmitted by a client; the network access equipment modifies the DHCP renewal message when the authentication state of a client user indicates that the client user passes authentication to carry a public network gateway address in the DHCP renewal message, and transmits the DHCP renewal message to a DHCP server to trigger the DHCP server to transmit a DHCP negative acknowledgement (NAK) message to the client; and after receiving the DHCP NAK message, the client releases a currently used Internet protocol (IP) address, and reapplies for an IP address.

Description

technical field [0001] The invention relates to network communication technology, in particular to a Portal secondary address authentication method and device. Background technique [0002] Portal means entrance in English. Portal authentication is usually also called web authentication, and the portal authentication website is generally called a portal website. As for the portal secondary address authentication, it means that the user obtains a private network IP address through the Dynamic Host Configuration Protocol (DHCP) before authentication. This private network IP address only allows the user to access the Portal server, and the set free access address is After the user is authenticated, the user will apply for a public IP address, which can be used to access network resources. The secondary address authentication of the portal solves the problem of IP address planning and allocation, and does not assign public IP addresses to users who have not passed the authenti...
