Problems solved by technology

[0005] When NAT444 linkage goes online, it is necessary to configure the address group, port block size, port block range, and interface application address group on the DP in advance, which may cause conflicts between the NAT configurations on the CP and DP, and affect user access.

Abstract

The present disclosure relates to a method and device for synchronizing NAT information. Wherein the method is applied to the forwarding plane of the virtual remote broadband access server, and the method includes: receiving a NAT information synchronization message from the control plane, and the NAT information synchronization message includes the NAT-related configuration of the control plane Parameters: set the NAT-related configuration parameters of the forwarding plane according to the NAT-related configuration parameters of the control plane. In this disclosure, the forwarding plane can synchronize the configuration parameters related to NAT from the control plane, without configuring the configuration parameters related to NAT on the forwarding plane, which is beneficial to prevent the NAT configuration conflict between the control plane and the forwarding plane, and can be done before the user requests to go online Make the NAT configurations of the control plane and the forwarding plane consistent, so as to ensure that users go online normally.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for synchronizing NAT information. Background technique [0002] NAT (network address translation, network address translation) converts private network addresses into public network addresses, so that private network hosts without legal public network addresses can also access the Internet (internet). NAT is a commonly used network technology for saving IPv4 addresses. [0003] Port block NAT divides each public network port into multiple independent port blocks. Each private address uses ports within the range of the port block for port translation. Port block NAT is a commonly used type of NAT on NAT444 gateways. NAT444 is an overall solution for deploying NAT in operator networks. NAT444 is based on port block NAT and PPPoE (Point-to-Point Protocol over Ethernet, point-to-point Ethernet bearer protocol) access, combined with AAA (...
