看了一下supernode的介绍
https://www.ntop.org/products/n2n/
an supernode: it is used by edge nodes at startup or for reaching nodes
behind symmetrical firewalls. This application is basically a directory
register and a packet router for those nodes that cannot talk directly.

不仅仅是登记用，而且是packet router

: edge1向supernode注册自己的内网ip，伪mac,公网ip和端口，获取edge2（虚拟ip2）的
