Configuration procedure

Configure NAT:

# Specify IP addresses for GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2.

<Router> system-view
[Router] interface gigabitethernet 1/0/1
[Router-GigabitEthernet1/0/1] ip address 192.168.0.2 24
[Router-GigabitEthernet1/0/1] quit
[Router] interface gigabitethernet 1/0/2
[Router-GigabitEthernet1/0/2] ip address 202.38.1.100 24
[Router-GigabitEthernet1/0/2] quit

# Configure ACL 2000 to identify packets from subnet 192.168.0.0/24.

[Router] acl basic 2000
[Router-acl-ipv4-basic-2000] rule permit source 192.168.0.0 0.0.0.255
[Router-acl-ipv4-basic-2000] quit

# Create address group 1, and add address 202.38.1.100 to the group.

[Router] nat address-group 1
[Router-nat-address-group-1] address 202.38.1.100 202.38.1.100
[Router-nat-address-group-1] quit

# Enable outbound PAT on interface GigabitEthernet 1/0/2 to translate the source address of outgoing packets matching ACL 2000 into the address in address group 1.

[Router] interface gigabitethernet 1/0/2
[Router-GigabitEthernet1/0/2] nat outbound 2000 address-group 1

Enable the ARP PnP feature on GigabitEthernet 1/0/1.

[Router] interface gigabitethernet 1/0/1
[Router-GigabitEthernet1/0/1] arp pnp
[Router-GigabitEthernet1/0/1] quit
