摘要
防火墙技术是网络安全的关键技术。文章介绍了一种基于DOM的,以FreeBSD操作系统为内核的防火墙的设计和实现,主要包括3个部分:FreeBSD操作系统目录结构的裁减、FreeBSD的断电保护设计以及使用FreeBSD的ipfw和natd实现防火墙的细节。在此基础上实现了设计,并且将此防火墙投入到实际使用当中,效果良好。
Firewall technology is the key technology of network security. In this paper,the design and implementation of a firewall with the FreeBSD kernel on the DOM are introduced. Cutdown of partial contents of the FreeBSD operating system, the design of protecting the FreeBSD operating system in the power cutoff accident and the details of configuring the FreeBSD firewall with ipfw and natd are described. The presented design has been put into use,which shows that the firewall is quite good.
