CISCO PIX 防火墙配置实践 ---- 介绍一个PIX防火墙实际配置案例,因为路由器的配置在安全性方面和PIX防火墙是相辅相成的,所以路由器的配置实例也一并列出。
PIX 防火墙
设置PIX防火墙的外部地址:
ip address outside 131.1.23.2
设置PIX防火墙的内部地址:
ip address inside 10.10.254.1
设置一个内部计算机与Internet上计算机进行通信时所需的全局地址池:
global 1 131.1.23.10-131.1.23.254
允许网络地址为10.0.0.0 的网段地址被PIX 翻译成外部地址:
nat 1 10.0.0.0
网管工作站固定使用的外部地址为131.1.23.11:
static 131.1.23.11 10.14.8.50
允许从RTRA发送到到网管工作站的系统日志包通过PIX防火墙:
conduit 131.1.
