[Firewall-Security] 端口映射及TCP转发软件源代码

Description:

端口映射

PortTransfer_三种模式。
(1) PortTransfer Port Dest_IP Port
在运行本程序的计算机上监听Port端口，并将所有连接请求转到Dest_IP的Port去
(2) PortTransfer ctrlIP ctrlPort Dest_IP Port
和模式3配合用，程序将先主动连接ctrlIP:ctrlPort,之后所有在模式3的ServerPort端口的请求转到Dest_IP:Port去
(3) PortTransfer ctrlPort ServerPort
在执行模式2前先执行，将监听ctrlPort和ServerPort 端口,ctrlPort供模式2使用，ServerPort提供服务.

模式1适合在网关上运行，将内网IP的端口映射到网关上，
如：PortTransfer 88 192.168.0.110 80
那么网关将开启88端口，所有在88端口的请求将转到内网的192.168.0.110的80端口

模式2和模式3联合使用可以将内网的IP和端口映射到指定的IP和端口上，
一般在公网IP(假设61.1.1.1)上执行模式3，如：PortTransfer 99 80, 80是映射过来的端口
内网用户执行模式2如：PortTransfer 61.1.1.1 99 127.0.0.1 80，
那么程序在内网将先连接61.1.1.1:99建立个连接，并等待接收命令。

之后当61.1.1.1的80端口有请求，将通过99端口命令内网机子和公网机子建立条新的数据连接，
并将请求通过新建的连接将请求转发到内网机.

最后更新:2007.8.31 By DSSZ

最新更改了模3,接收到新连接接令后,不再创建新的临时端口,避免中转服务器有防火墙,临时端口连接不上的情况!
可参看 PortTransfer_3 的修改部分,在transport_old.cpp里面
