VPN Server和Client 根据一条Key (4096 bytes)然后不定时转 port,那么他们不知道怎样block?

如题,不知道是否有这样的东西?

就是1秒就转一次port,那么怎样block呢?

没有人有反应?

You increase your own complexity: synchronization, sending and resembling incoming packets, resending mechanism, etc.

For blocker, if I found some communication between two IPs are unknown, I simply drop these traffic no matter which port you are using...

I prefer obfsproxy technique.

If the same mechanism and methodology apply to the IP address as well, what do you think?
