I'd like to share a simple NAT configuration on NE router, Here we configure easy-IP mode for NAT pool, which means that NAT will choose the interface IP address to make the NAT.

1. create NAT instance, Binding a Service Board to a NAT Instance

[~HUAWEI] service-location 1

[*HUAWEI-service-location-1] location slot 1

[*HUAWEI-service-location-1] commit

[~HUAWEI-service-location-1] quit


[~HUAWEI] service-instance-group group1

[*HUAWEI-service-instance-group-group1] service-location 1

[*HUAWEI-service-instance-group-group1] commit

[~HUAWEI-service-instance-group-group1] quit


[~HUAWEI] nat instance nat1 id 1

[*HUAWEI-nat-instance-nat1] service-instance-group group1

[*HUAWEI-nat-instance-nat1] commit

[~HUAWEI-nat-instance-nat1] quit



 2. configure easy IP NAT pool, here we suppose the outbound interface is 0/2/1

[~HUAWEI] nat instance nat1 id 1

[*HUAWEI-nat-instance-cpe1] nat address-group group1 group-id 1 unnumbered interface GigabitEthernet 0/2/1


 3. confiure ip address for outbound interface:

[~HUAWEI] interface gigabitEthernet 0/2/1

[~HUAWEI-GigabitEthernet0/2/1] ip address

[*HUAWEI-GigabitEthernet0/2/1] commit

[~HUAWEI-GigabitEthernet0/2/1] quit


4. configure ACL to match the traffic that need to do the NAT:

[~HUAWEI] acl 3001

[*HUAWEI-acl4-advance-3001] rule 5 permit ip source

[*HUAWEI-acl4-advance-3001] commit

[~HUAWEI-acl4-advance-3001] quit

5. apply NAT at the outbound interface: 

[~HUAWEI] interface gigabitEthernet 0/2/1

[*HUAWEI-GigabitEthernet0/2/1] ip address

[*HUAWEI-GigabitEthernet0/2/1] nat bind acl 3001 instance nat1

[*HUAWEI-GigabitEthernet0/2/1] commit

[~HUAWEI-GigabitEthernet0/2/1] quit
