Abstract

The invention discloses a method and system for enabling a VXLAN (Virtual eXtensible LAN) message to traverse NAT (Network Address Translation) equipment. The method comprises the steps of: receivinga first VXLAN message which is from a source VTEP (VXLAN Tunnel End Point) on a private network side and is sent to a target VTEP on a public network side; if an NAT rule matched with the first VXLANmessage exists, after carrying out public network conversion on a source IP address and a source port number of the first VXLAN message, sending to the target VTEP; receiving a second VXLAN message which is from the target VTEP and is sent to the source VTEP; and after determining that the second VXLAN message is matched with the NAT rule, after carrying out private network conversion on a targetIP address and a target port number of the second VXLAN message, sending back to the source VTEP. The invention can avoid the problem that the VXLAN message sent from equipment on the public network side cannot traverse the NAT equipment.

Description

technical field [0001] The invention relates to a technology for forwarding XLAN messages from a NAT device, in particular to a method, a system and a storage medium for a VXLAN message to pass through a NAT device. Background technique [0002] VXLAN (Virtual eXtensible LAN, Extensible Virtual Local Area Network) is a technology that uses the encapsulation form of "MAC inUDP" to encapsulate Layer 2 packets into a Layer 3 network. It provides a Layer 2 interconnection for distributed users. method, and can provide business isolation for different tenants. With the rapid development of virtualization technology, VXLAN technology has been widely used. [0003] VTEP (VXLAN Tunnel End Point, VXLAN tunnel terminal) is used as the termination point of the VXLAN tunnel to perform VXLAN encapsulation and decapsulation operations on data, such as figure 1 As shown; Terminal A sends the message to VTEPA, VTEPA encapsulates the message in VXLAN, and passes through the network without...
