Problems solved by technology

[0004] But at the same time, with the continuous expansion of Internet coverage and the increasing importance of network security, it is increasingly necessary to trace the source of private network users accessing the public network. However, there is no user traceability for NAT technology in the existing technology Methods

Abstract

The present invention provides a user traceability method, device, and broadband access server. The method includes: receiving a traceability request, and querying a currently stored first log record according to the traceability request, and the first log record includes the public network IP address, the starting port identifier and the ending port identifier of the port segment corresponding to the public IP address, the private network IP address, the public network IP address and the port segment are assigned to the distribution of the private network IP address at the same time time range, to obtain the corresponding private network IP address; according to the traceability timestamp and the private network IP address, query the second log record currently stored, the second log record includes the private network IP address, user identification The user corresponding to the user identifier uses the usage time range of the private network IP address to obtain the corresponding user identifier. Through this solution, users can be traced effectively and accurately, and the supervision of Internet network security can be strengthened.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for user traceability and a broadband access server. Background technique [0002] As the number of Internet users continues to increase, how to solve the shortage of public network IP addresses has become a research focus. For this reason, Network Address Translation (NAT for short) technology, also known as Carrier-Grade NAT (Carrier-Grade NAT for short) CGN) technology is proposed. Specifically, the CGN device converts the private IP address into a public IP address by allocating different ports corresponding to the same public IP address for the private IP address according to the received public network access request including the private IP address , so that multiple private network users can share a public network IP address for external network connection. [0003] An existing NAT solution is that when a CGN device receives a public network access ...
