防火墙，自动操作不感觉好吗？这个程序是允许的哟…

基于tdi驱动的个人防火墙，用vc++实现，是一个开源的防火墙-Tdi-driven based on the personal firewall, using vc++ Realized, is a open source firewall

一个VPN软件（freeswan）的源码可编译，有MakeFile文件 -A VPN software (freeswan) can compile the source code, Makefile document has

The doorman guards the door of a server, manipulating firewall rules to admit only recognized parties

基于ndis层的防火墙，相对TDI和SPI的防火墙，ndis防火墙更加底层，能过滤所有的网络底层包-Based on the NDIS layer firewalls, relative TDI and SPI firewall, ndis firewall more bottom to filter the bottom of all network packets

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.

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
