Networking Requirements

As shown in Figure 1, private network users in Area A and Area B of a company connect to the Internet. The public IP address of GigabitEthernet3/0/0 on the router is 202.169.10.1/24. The IP address of the carrier device connected to the router is 202.169.10.2/24. Users in Area A want to use addresses in the public address pool (202.169.10.100 to 202.169.10.200) to replace IP addresses (192.168.20.0/24) of hosts in Area A in NAT mode to access the Internet. Users in Area B want to use addresses in the public address pool (202.169.10.80 to 202.169.10.83) to replace IP addresses (10.0.0.0/24) of hosts in Area B to access the Internet.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure IP addresses for ports, default route, and outbound NAT on the WAN interface to allow internal hosts to access external networks.

Procedure

  1. Configure an IP address for ports on the router. 

    <Huawei> system-view [Huawei] sysname Router [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 202.169.10.1 24  [Router-GigabitEthernet3/0/0] quit


  2. Configure a default route with next hop address 202.169.10.2 on the router. 

    [Router] ip route-static 0.0.0.0 0.0.0.0 202.169.10.2


  3. Configure outbound NAT on the router. 

    [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
