简单个人防火墙 可拦截IP包

通信机制：C-S-C中继在中间，代理为控制台提供双向服务，承诺控制台命令并向代理发送文件，代理命令返回执行结果文件并开始接收，接收信号的功能。此外，继电器接受控制台（与类似的代理，DosPipe实现）。这样的设计是为了解决穿透防火墙或路由器（NAT）的障碍——由连接代理发起，由内向外路由，然后中继到控制目的。通过预定顺序的中继文件地址，由搜索代理循环中继；连接，通过文件传输功能更新地址顺序。

以前对防火墙接触甚少，所了解的也是从系统底层实现角度看的一些分析细节，最近由于毕业设计的需要，对防火墙的发展、分类、现状和趋向等方面做了概略的了解，也有一些体会，做个简单的分析报告。 -previously little contact with the firewall, as well as knowledge of the underlying system from the point of view of achieving the details of some analysts, the recent graduate design needs, the development of firewall, classification, and the status and trends so on a broad understanding, have some experience and become a simple analysis.

ip-filter不但具有SNAT、DNAT、端口映射、透明代理等已经成熟的功能，同时还实现了IPv4和IPv6协议以及IPSec安全协议的支持。此外还有诸如规则分组、blackhole、数据包捕获等特色-ip-filter not only had SNAT, DNAT, the port mapping, the transparent proxy and so on already the mature function, meanwhile has realized IPv4 and the IPv6 agreement as well as the IPSec security agreement support. In addition also has such as the rule grouping, blackhole, characteristic and so on data packet capture
