推荐答案
NAT穿透力是足够复杂，你真的不应该惹它，直到你很熟悉网络的内部。该使用的是pretty艺术的许多国家，这些天。
NAT penetration is complex enough that you really shouldn't mess with it until you're quite familiar with the internals of networking. The autonomous NAT traversal used by pwnat is pretty much the state of the art these days.
的基本思想是使用一个事实，即路由器可能具有的任何IP地址和尽可能在NAT都知道，任何的源IP地址是有效的一个ICMP错误消息，这在NAT将转发到它的客户机。
The basic idea is to use the fact that a router might have any IP address and as far as a NAT knows, any source IP address is valid for an ICMP error message, which the NAT will forward to its client.
请注意，你通常只能打通UDP。所以你必须实现自己的字节流协议。
Note that you can usually only get UDP through. So you'll have to implement your own byte-stream protocol.
