KingSocket firewall Development Kit v2.0

用于检验局域网内的网卡处于混杂模式的主机，维护网络安全-it is the software for checking the network card in the LAN and the host computer which is in the jam,protecting the security of the net.

ibdnet为几个低级网络例程提供了一个简化的接口在，包括网络地址处理，内核arp(4) 和 route(4)表处理，防火墙，接口配置，以及原始以太网和IP数据包传输。-ibdnet network of several low-level routines to provide a simplified interface, including network addresses, core arp (4) and route (4) Table processing, firewall, port configuration, and the original Ethernet and IP packet transmission.

一个 ip过滤源代码的c++工程，可以看作简单的防火墙，希望对大家有帮助-an ip filter source code c works can be seen as a simple firewall, and I hope to be helpful

这是一个简单的防火墙，用VB开发的，功能很少，不过可以借鉴一下编程方法，很有用的-This is a simple firewall, using VB, functional little, but I can learn some lessons from programming, a very useful

一个简单的个人防火墙的例子程序源码- A simple individual firewall example procedure source code

vc++ 实现的防火墙，可是实现自己定义规则，防止ping，断开网络，监听网络等功能。-vc++ realize the firewall, but realize their own definition of rules to prevent ping, disconnect the network, monitor network functions.

ipsec vpn的例子程序 主要是演示vpn-ipsec ipsecsample-app.rar

这实际上己经是IISLogView的第三个版本了，最初写它的原因是实在无法忍受用记事本去查IIS的日志文件，所以就用BCB写了个小程序，当时的功能也十分简单，就是把IIS的日志文件塞到一个表格控件里面去，让它看起来舒服些。后来又添加了简单的筛选过滤功能，只是使用基本的字符串比较加上一些逻辑组合。因为是为读取IIS日志而设计的所以便命名为IISLogView了，不过实际上它已经可以支持所有的W3C格式的日志文件了，包含WINDOWS防火墙的日志文件。 版权所有 请勿乱传播-by IISLogView is the third version of the initial writing of the reasons for it is really could not bear to use the notebook to go IIS log files, using BCB wrote a small program, the function is also very simple, that is the IIS log files Bridge forms a component inside, it look a little more comfortable. Then add a simple screening filter function, but the basic use of the string comparison with some logical combination. Because it is read to the IIS log designed so named IISLogView, but in reality it can support all the W3C log file formats, including Windows firewall log file. Copyright do not spread chaos

微软的一个ndis驱动程序例子,写防火墙的朋友可以参考-A ndis driver example of Microsoft. and it can be referred to those who writes the firewall

防火墙提供了内核模式的防火墙和 NAT 机制，这些机制可以通过用户模式运行的接口程序进行监视和控制。 防火墙规则可以使用 ipf(8) 工具来动态地设置和删除。 NAT 规则可以通过 ipnat(1) 工具来维护。 ipfstat(8) 工具则可以用来显示 IPFILTER 内核部分的统计数据。 最后， 使用 ipmon(8) 程序可以把 IPFILTER 的动作记录到系统日志文件中。 -Firewall provides a kernel-mode firewall and NAT mechanisms, these mechanisms can be run through the user-mode interface program to conduct surveillance and control. Firewall rules can use the ipf (8) tools to dynamically set up and delete. NAT rules can be adopted ipnat (1) tools to maintain. ipfstat (8) tools can be used to show the core part of IPFILTER statistics. Finally, the use of ipmon (8) program can record the movements IPFILTER to the system log file.
