TCP端口映射工具，有几种工作模式，可以简单的映射端口，可以通过几种模式配合实现端口反弹（在防火墙只允许单向访问的时候将内网的服务映射到外网）可以实现在只允许访问一个端口的情况下访问任意端口等。可以对TCP数据加密，防止在网络上被人监听。可以多种模式串联起来实现复杂网络环境下的网络访问(TCP port mapping tool, there are several operating modes, can simply map the port, with the port rebound (in the firewall to allow only one-way access when mapped within network services to the external network) through several modes can be achieved in only access to any port, such as in the case to allow access to a port. TCP data encryption, to prevent be listening on the network. Series can be a variety of modes of the complex network environment, the network access)

什么是防火墙？防火墙就是一种过滤塞（目前你这么理解不算错），你可以让你喜欢的东西通过这个塞子，别的玩意都统统过滤掉。在网络的世界里，要由防火墙过滤的就是承载通信数据的通信包。(failed to translate)
