Abstract
Embodiments of this application disclose a communication method and a related device. The method includes: A symmetric device listens on N local public ports, where N is a natural number greater than 1; and when the symmetric device receives a hole punching packet from the N local public ports, the symmetric device sends a response packet to a cone device based on the hole punching packet, so that the symmetric device establishes a communication connection to the cone device, where the hole punching packet is sent by the cone device, and the response packet carries a first network information mapping relationship. The cone device may directly communicate with the symmetric device, so that there is no need for a server having a data relay function, and costs of deploying the server are reduced.
