On the problem that symmetric NAT cannot traverse NAT, my suggestion

When the moon node was first started,The node transfer module will be automatically opened,And it is set that when a client fails to penetrate, it will send a penetration failure message to this node, and this node will automatically forward the data flow of the virtual LAN for the client.At the same time, you can also force all data of the virtual LAN where one or all clients are located to be forwarded by this node through commands。
Thanks for an amazingly great product!
