Abstract

The disclosure provides an authentication-free access method, which is applied to a gateway device, and the method is: receiving the first DNS query message sent by the terminal to the DNS server; if the domain name list includes the first DNS query message to be queried A domain name, then forward the first DNS query message; the domain name list is used to record the domain name in the DNS query message received by the gateway device; if the domain name list does not include the first domain name and the first domain name and the pre-configured authentication-free If the domain name matches, the first domain name is recorded in the domain name list, and the second DNS query message is sent to the DNS server. The source IP address of the second DNS query message is the address of the gateway device, and the second DNS query message is also used for Query the first domain name; if a DNS response message indicating that the domain name resolution is successful for the second DNS query message is received, configure a release rule for the resolved first IP address, and forward the first DNS query message.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to an authentication-free access method and gateway equipment. Background technique [0002] When a user accesses the network, the gateway device can control the user's access to the network. For example, the gateway device can cooperate with the authentication server to authenticate the identity of the user, and grant access to the external network to the authenticated user. For another example, the gateway device can exempt certain domain names from authentication, so that users can access designated websites or servers without authentication. [0003] One of the authentication-free access schemes is: configure authentication-free rules on the gateway device for the domain names of websites or servers that can be accessed without authentication; ) The server queries the IP (Internet Protocol, Internet Protocol) address corresponding to this type of domain nam...
