Intranet and extranet communication method, device and system, proxy server and storage medium

Abstract

The invention discloses an intranet and extranet communication method, device and system, a proxy server and a readable storage medium, and the method is applied to the proxy server of an extranet, and comprises the steps: obtaining a data message sent by an extranet node; determining identification information of a target intranet node carried in the data message; and sending the data message to the corresponding target intranet node according to the identification information, so that the target intranet node executes a corresponding operation according to the information of the data message. According to the invention, the data message containing the identification information of the corresponding target intranet node and actively sent by the extranet node can be forwarded to the corresponding target intranet node; therefore, the target intranet node executes the corresponding operation according to the data message, namely, when the intranet and the extranet communicate with each other, the extranet node does not passively wait for the connection of the intranet node, but can actively realize the communication with the target intranet node, so that the requirement that the extranet node hopes to actively communicate with the intranet node is met.

Description

technical field [0001] The present application relates to the technical field of network communication, and more specifically, relates to a method, device, and system for intranet and intranet communication, a proxy server, and a computer-readable storage medium. Background technique [0002] Under the traditional penetrating NAT (Network Address Translation, Network Address Translation), the communication between internal and external network nodes is realized by actively connecting internal network nodes to external network nodes, that is to say, external network nodes can only passively wait for internal network nodes If the external network node wants to actively communicate with the internal network node, such as connecting to the internal network node or controlling the internal network node, the traditional communication method cannot meet the needs of the external network node. Contents of the invention [0003] The purpose of this application is to provide a metho...
