nat技术实验(纯干货)
实验步骤:
第一步:设置lsw1交换机配置:
-int g0/0/1
-port link-type access
- port default vlan 10
-un sh
-int g0/0/2
-port link-type access - port default vlan 20
-un sh
-int g0/0/3
-port link-type access - port default vlan 30
-un sh
-int g0/0/4
-port link-type access - port default vlan 20
-un sh
-int g0/0/6
-port link-type access - port default vlan 10
-un sh
-int g0/0/5
-port link-type access - port default vlan 40
-un sh
-int Vlanif 10
-ip add 192.168.10.1 24
-int Vlanif 20
-ip add 192.168.20.1 24
-int Vlanif 30
-ip add 192.168.30.1 24
-int Vlanif 40
-ip add 11.0.0.2 24
-Dis ip int b (查看配置信息)
IP route-static 0.0.0.0 0.0.0.0 11.0.0.1 )
第二步:设置r1路由器:
-int g0/0/0
-ip add 11.0.0.1 24
-un sh
-int g0/0/1
-ip add 12.0.0.1 24
-un sh
-ip route-static 0.0.0.0 0.0.0.0 12.0.0.2 向上只默认
-ip route-static 192.168.10.0 24 11.0.0.2 (数据转发路由)
-ip route-static 192.168.20.0 24 11.0.0.2
-ip route-static 192.168.30.0 24 11.0.0.2 向下静态的同网段不用写路由
(-nat static global 8.8.8.8 inside 192.168.10.10 (pc1)
-int g0/0/1
-nat static enable)
(-nat address-group 1 212.0.0.100 212.0.0.200 (pc20网段)
-acl 2000 (定义总规则)
-rule permit source 192.168.20.0 0.0.0.255 (定义总规则的明细)
-rule permit source 11.0.0.0 0.0.0.255
-int g0/0/1
-nat outbound 2000 address-group 1 no-pat ) 公私匹配
(-acl 3000
-rule permit ip source 192.168.30.0 0.0.0.255 (pc30网段)
-int g0/0/1 同网段不需要配回城路由
-nat outbound 3000 )
(-int g0/0/1
-nat server protocol tcp global 9.9.9.9 www inside 192.168.10.100 www
)
第三步:设置r2路由器:
(-int g0/0/0
-ip add 12.0.0.2 24
-un sh
-int g0/0/1
-ip add 13.0.0.1 24
-un sh
-int loo 0
-ip add 114.114.114.114 32
-ip route-static 9.9.9.9 32 12.0.0.1 pc服务器
-ip route-static 8.8.8.8 32 12.0.0.1 pc1
-ip route-static 212.0.0.0 24 12.0.0.1 pc 2 4
