三.特殊命令及要求
防火墙nat 实验
1, 内网网段配置动态pat 将内网 192.168.1.0 网段映射到防火墙外网接口上
ciscoasa(config)# nat (inside) 1 192.168.1.0 255.255.255.0
ciscoasa(config)# global (outside) 1 interface
2，dmz 区域服务器做静态pat 将 两台服务器对应到一个外网接口的不同端口
static (dmz,outside) tcp 202.106.0.150 80 172.16.0.100 80
static (dmz,outside) tcp 202.106.0.150 23 172.16.0.200 23
access-list abc permit ip any host 202.106.0.150
access-group abc in int outside
3， 开启nat 控制
nat-control
4， 对内网网段192.168.2.0 或豁免 能够发访问外网
access-list bbs permit ip 192.168.2.0 255.255.255.0 host 202.106.0.2
nat (inside) 0 access-list bbs
