简单的ACL控制实验

Posted 2021-01-29

实验名称：简单ACL控制实验
实验拓扑：

实验要求：
模拟一个简单的公司内部网络
WG用一个路由器来模拟。
-路由器R1 只允许WG远程登陆
-YF和CW之间不能互通，但都可以和WG互通
-WG和YF可以访问Client1
-YF和CW只能访问server的www服务
-只有WG才能访问server1的所有服务
-网关设置都为.254
实验步骤：
1、先按照图中的地址，进行配置。并做通链路。
#R1

ip address 192.168.12.1 255.255.255.252
interface GigabitEthernet0/0/2
ip address 192.168.13.1 255.255.255.252

  interface GigabitEthernet0/0/1
    ip address 192.168.10.254 255.255.255.0 
 interface GigabitEthernet0/0/2
    ip address 192.168.20.254 255.255.255.0

#wg

interface GigabitEthernet0/0/0
ip address 192.168.10.1 255.255.255.0
ip route-static 0.0.0.0 0.0.0.0 192.168.10.254

检查互通之后
2、进行控制访问ACL的配置
#R1：
-配置telnet
-仅能允许WG访问telnet
acl 2000
rule permit source 192.168.10.1 0
rule deny source any

telnet server enable

user-interface vty 0 4
acl 2000 inbound
authentication-mode aaa
aaa
local-user tedu password cipher tedu
local-user tedu server-type telnet

#R2：
YF主机访问控制
-YF和CW之间互能互通
-YF可以和WG和Client1 互通
-YF 只能访问Server1的www服务
acl 3000
rule 5 permit ip source 192.168.20.1 0 destination 192.168.10.1 0
rule 10 permit ip source 192.168.20.1 0 destination 1.1.1.1 0
rule 15 permit tcp source 192.168.20.1 0 destination 192.168.1.1 0 destination-port eq www

interface g0/0/2
traffic-filter inbound acl 3000

#R3
CW主机访问控制
-CW和YF、client1 之间不能互通
-CW可以和WG互通
-CW只能访问server1 的www服务
acl 3000
rule permit ip source 192.168.30.1 0 destination 192.168.10.1 0
rule permit tcp source 192.168.30.1 0 destination 192.168.1.1 0 destination-port eq 80
rule deny ip source any
interface g0/0/1
traffic-filter inbound acl 3000

3、验证
