Configure an internal user to access the Internet using a NAT address pool on the AR router
A Huawei AR router allows internal users to access external servers and the Internet using a NAT address pool. The configuration is as follows: 1. Assign IP addresses to interfaces on the router. [Huawei] vlan 100 [Huawei-vlan100] quit [Huawei] interface vlanif 100 [Huawei-Vlanif100] ip address 192.168.20.1 24 [Huawei-Vlanif100] quit [Huawei] interface ethernet 2/0/0 [Huawei-Ethernet2/0/0] port link-type access [Huawei-Ethernet2/0/0] port default vlan 100 [Huawei-Ethernet2/0/0] quit [Huawei] interface gigabitethernet 3/0/0 [Huawei-GigabitEthernet3/0/0] ip address 202.169.10.1 24 [Huawei-GigabitEthernet3/0/0] quit 2.
