Static NAT444 configuration example
Network requirements
As shown in Figure 74, configure static NAT444 to allow users at private IP addresses 10.110.10.1 to
10.110.10.10 to use public IP address 202.38.1.100 for accessing the Internet. Configure the port
range as 10001 to 15000, and set the port block size to 500.

Configuration procedure
# Specify IP addresses for the interfaces on the router. (Details not shown.)
# Create NAT port block group 1.
<Router> system-view
[Router] nat port-block-group 1
# Add the private IP addresses from 10.110.10.1 to 10.110.10.10 to the port block group.
[Router-port-block-group-1] local-ip-address 10.110.10.1 10.110.10.10
# Add the public IP address 202.38.1.100 to the port block group.
[Router-port-block-group-1] global-ip-pool 202.38.1.100 202.38.1.100
# Set the port block size to 500.
[Router-port-block-group-1] block-size 500
# Configure the port range as 10001 to 15000.
[Router-port-block-group-1] port-range 10001 15000
[Router-port-block-group-1] quit
# Apply the port block group 1 to the outbound direction of GigabitEthernet 2/0/2.
[Router] interface gigabitethernet 2/0/2
[Router-GigabitEthernet2/0/2] nat outbound port-block-group 1
[Router-GigabitEthernet2/0/2] quit
