配置设备介绍:(只为做实验实际应用请根据自己具体情况更改相关参数即可) 核心交换机 4507

提供VLAN3 网关地址:192.168.3.254 提供 DNS 服务器连接:192.168.0.1

接入交换机 2960

提供 VLAN3 TURNK 连接, 可用IP 地址为

192.168.3.0-192.168.3.240 掩码:255.255.255.0 网关:192.168.3.254 DNS: 192.168.0.1

内网实验防火墙 CISCO ASA 5510 E0/0 IP:192.168.3.234 E0/1 IP 10.1.1.1

实现配置策略

1. 动态内部 PC1 DHCP 自动获得IP 地址,可访问INTERNET,并PING 通外部网关。 PC1 Ethernet adapter 本地连接:

Connection-specific DNS Suffix . : gametuzi Description . . . . . . . . . . . : Broadcom 440x roller Physical Address. . . . . . . . . : 00-13-77-04-9 Dhcp Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IP Address. . . . . . . . . . . . : 10.1.1.20 Subnet Mask . . . . . . . . . . . : 255.255.0.0 Default Gateway . . . . . . . . . : 10.1.1.1 DHCP Server . . . . . . . . . . . : 10.1.1.1 DNS Servers . . . . . . . . . . . : 192.168.0.1

2. 静态内部 PC2 手动分配地址,可访问 INTERNET ,并PING 通外部网关。 PC1 Ethernet adapter 本地连接:

Connection-specific DNS Suffix . : gametuzi Description . . . . . . . . . . . : Broadcom 440x roller Physical Address. . . . . . . . . : 00-13-77-04-9 Dhcp Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IP Address. . . . . . . . . . . . : 10.1.34.34 Subnet Mask . . . . . . . . . . . : 255.255.0.0 Default Gateway . . . . . . . . . : 10.1.1.1 DHCP Server . . . . . . . . . . . : 10.1.1.1
