I have found a new project which I have to say it's more powerfull than n2n

[LysLee111]

But the probrom is that its server is not open source, so it may contain a backdoor Guys help me to check it: https://github.com/openp2p-cn/openp2p

server side is open source(not full version) https://github.com/openp2p-cn/gateway-lite

The project is different from N2N, but I would suggest again N2N to utilize the public DHT network for hole-punching.

该项目与 N2N 不同，但我再次建议 N2N 利用公共 DHT 网络进行打孔。

打孔可以考虑QUIC

Modified tinc vpn is better. I have switched to it.
