What does the hole mean? Server (Tencent), A, B two client (QQ) A, B, bute, I can't send information, I don't understand that I will apply to the server to give it to it. When the server wants to send one: Broadway to the passage (this is a hole), the hole is a direction, it turns out that QQ is a hole in every minute, and I have not measured QQ to keep the port map. How long does it take to make a hole? Is it true? I'm listening to the UDP package qq sent to the server to the server to the server is because the UDP package is not connected to the connection. Anyq has a source agent, you will go with it, you will be a minute. For 30 seconds, you can keep it implied, you can only use it on UDP! ! ! Of course, QQ consumes system resources.
