1.配置接口IP地址

[Router] vlan 100
[Router-vlan100] quit
[Router] interface vlanif 100
[Router-Vlanif100] ip address 192.168.20.1 24
[Router-Vlanif100] quit
[Router] interface ethernet 2/0/0
[Router-Ethernet2/0/0] port link-type access
[Router-Ethernet2/0/0] port default vlan 100
[Router-Ethernet2/0/0] quit
[Router] vlan 200
[Router-vlan200] quit
[Router] interface vlanif 200
[Router-Vlanif200] ip address 10.0.0.1 24
[Router-Vlanif200] quit
[Router] interface ethernet 2/0/1
[Router-Ethernet2/0/1] port link-type access
[Router-Ethernet2/0/1] port default vlan 200
[Router-Ethernet2/0/1] quit
[Router] interface gigabitethernet 3/0/0
[Router-GigabitEthernet3/0/0] ip address 202.169.10.2 24
[Router-GigabitEthernet3/0/0] quit
2.配置缺省路由，指定下一跳地址為202.169.10.1
[Router] ip route-static 0.0.0.0 0.0.0.0 202.169.10.1
3.配置NAT Outbound
[Router] nat address-group 1 202.169.10.100 202.169.10.200
[Router] nat address-group 2 202.169.10.80 202.169.10.83
[Router] acl 2000
[Router-acl-basic-2000] rule 5 permit source 192.168.20.0 0.0.0.255
[Router-acl-basic-2000] quit
[Router] acl 2001
[Router-acl-basic-2001] rule 5 permit source 10.0.0.0 0.0.0.255
[Router-acl-basic-2001] quit
[Router] interface gigabitethernet 3/0/0
[Router-GigabitEthernet3/0/0] nat outbound 2000 address-group 1 no-pat
[Router-GigabitEthernet3/0/0] nat outbound 2001 address-group 2
[Router-GigabitEthernet3/0/0] quit

配置舉例:
