Optimize NAT traversal and support multiple listening modes.

[lp-learn]

In this commit, we have optimized NAT traversal and added support for multiple listening modes. By improving network communication and enhancing protocol support, we have increased the success rate and reliability of NAT traversal. Additionally, we have added support for multiple listening modes to allow applications to more flexibly adapt to different network environments.

These improvements will enhance the user experience and make applications more reliable across a variety of network conditions.

Please note that these changes may require some testing and validation to ensure they work properly in various scenarios. Please search for related changes in the code and test accordingly.
