Abstract

The present application discloses a message transmission method, device, computer equipment, and storage medium. The message transmission method includes: receiving a first forward message encapsulated by VXLAN sent by a first user terminal; Obtain the first public network IP address according to the VNI network identifier of the first forward message, and obtain the first public network port according to the quintuple information of the first forward message; convert the source IP address of the first forward message to the first public network IP address, and converting the source port of the first forward message to the first public network port; and sending the first forward message to the service system. By using the VNI network identifier to associate with the public network IP address, and assigning the corresponding public network IP address to the forward message according to the VNI network identifier of the forward message, the user terminals in each LAN can use the public IP addresses corresponding to each LAN. The network IP address can be used to access the server on the external network, so as to solve the problem of multi-LAN IP conflicts.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message transmission method, device, computer equipment, and storage medium. Background technique [0002] With the rapid increase in the number of computers connected to the Internet, public network IP address resources are increasingly stretched. Generally, even for large-scale LAN users with hundreds of computers, when they apply for a public IP address, the public IP addresses allocated are only a few or a dozen. Obviously, such a small number of public network IP addresses cannot meet the needs of network users at all, so Network Address Translation (NAT) was born. [0003] NAT is the process of converting the IP address in the data packet header to another IP address. Currently, when using NAT technology for packet transmission, IP conflicts are prone to occur between multiple LANs. Contents of the invention [0004] Embodiments of the present app...
