description The invention discloses a network address translation (NAT) information acquisition method. The NAT information acquisition method comprises the steps: establishing an intercommunication channel between a broadband remote access server (BRAS) device and a carrier-grade NAT (CGN) device; through the intercommunication channel, receiving NAT information, which is transmitted by the CGN device; transmitting the NAT information to a server, thereby ensuring that a user searches for the NAT information through the server. The invention further discloses a BRAS device. Establishment of a channel, for transmitting associated information, between a distributive BRAS device and an independent CGN device is implemented, so that user-associated NAT information is convenient to be directly acquired at the BRAS device. 本发明公开了种获取NAT信息的方法，通过建立宽带远程接入服务器BRAS设备与运营商级NAT CGN设备之间的互通通道；通过所述互通通道接收所述CGN设备发送的NAT信息；将所述NAT信息发送给服务器，以使得用户通过所述服务器查找所述NAT信息。本发明还公开了种BRAS设备，实现在分布式BRAS设备和独立式CGN设备之间建立条通道，用来传递相关信息，从而方便的在BRAS设备上直接获取用户相关的NAT信息。
