How do I configure the AR router to map multiple internal IP addresses to external IP addresses using a NAT address pool

A Huawei AR router can use the NAT address pool to implement mapping between internal IP addresses and public IP addresses in the public address pool. The configuration is as follows:
1. Configure a NAT address pool on the router.
[Huawei] nat address-group 1 202.169.10.100 202.169.10.200
2. Configure an ACL rule to permit the internal address segment that allows NAT translation.
[Huawei] acl 2000
[Huawei-acl-basic-2000] rule 5 permit source 192.168.20.0 0.0.0.255
[Huawei-acl-basic-2000] quit
3. Associate outbound NAT with an address pool on an outbound interface
[Huawei] interface gigabitethernet 3/0/0
[Huawei-GigabitEthernet3/0/0] ip address 202.169.10.1 24
[Huawei-GigabitEthernet3/0/0] nat outbound 2000 address-group 1
[Huawei-GigabitEthernet3/0/0] quit
