Abstract

The present application discloses a NAT conversion method, device, computer equipment, and storage medium. The NAT conversion method includes: obtaining the corresponding first public network IP address segment according to the first IP address of the first local area network to which the first user terminal belongs; Obtain the first public network IP address from the first public network IP address segment, and assign the first public network IP address and the first public network port to the first user terminal; receive the first forward report sent by the first user terminal text; convert the source IP address of the first forward message to the first public network IP address, and convert the source port of the first forward message to the first public network port, and convert the first forward message after NAT Send the message to the server. In this application, by corresponding the IP address of the local area network with the public network IP address segment, each local area network is assigned a corresponding public network IP address segment, and the user terminal in the local area network can use the corresponding public network IP address segment to access the server on the external network, Thereby, the problem of IP conflict among multiple local area networks can be solved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a NAT conversion 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 application...
