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 invention provides a user tracing method and device and a broadband access server. The method comprises the following steps: receiving a tracing request, inquiring a currently-stored first log record according to the tracing request, and acquiring a corresponding private network IP address, wherein the first log record comprises a public network IP (Internet Protocol) address, the starting port identity and the ending port identity of a port segment corresponding to the public network IP address, a private network IP address, and an allocation time range in which the public network IP address and the port segment are allocated to the private network IP address at the same time; and inquiring a currently-stored second log record according to a tracing time stamp and the private network IP address, and acquiring a corresponding user identity, wherein the second log record comprises the private network IP address, a user identity and a usage time range in which a user corresponding to the user identity uses the private network IP address. Through a scheme, the user is traced effectively and accurately, and the supervision of Internet network security is enhanced.

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 ...
