[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

[Proxy Server] kingate-1.6.tar

Description: kingate是一个代理服务器，能代理多种协议,包括：http,https,socks,ftp,pop3,smtp,telnet,dns。能运行在linux,freebsd,...及其它类unix,还有windows(最新版本要求nt 4.0以上)操作系统上 kingate是一个多线程的程序(采用线程池的方式),所以短时间内大量的连接请求,kingate还能保持很高的性能。 kingate还支持tcp端口映射,可以实现别人访问你的内网主机。-kingate is an agent server, can act the many kinds of agreements, including: Http, https, socks, ftp, pop3, smtp, telnet, dns. Can move in linux, freebsd.. And other kind of unix, but also has windows (the newest edition to request above nt 4.0) on the operating system kingate is a multi-thread procedure (uses line Cheng Chi the way), therefore in the short time the massive connections requested, kingate also can maintain the very high performance. Kingate also supports the tcp port mapping, may realize the others to visit you in webmaster machine.
