6.3.2 (Optional) Configuring an NAT Address Pool
To ensure that response packets still pass through the SPU when user requests pass through links
of different ISPs, you need to configure an NAT address pool for translating source addresses
through NAT.
Context
The NAT address pool takes effect only when it is bound to a Layer 3 classifier or a load balancing
member instance.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
nat address-group group-index start-address end-address
An NAT address pool is configured.
Up to 1024 NAT address pools can be configured.
By default, no NAT address pool is configured.
The IP address of the outbound interface must be different from any IP address in the NAT
address pool that is bound to the Layer 3 classifier referenced by the load balancing policy on
the outbound interface.
l If the IP address of the outbound interface is the same as an IP address in the NAT address
l After the Layer 3 classifier or the load balancing instance is bound to the NAT address pool,

Data
Parameters of the Layer 7 classifier, including the classifier name and matching rule
Name and parameters of the load balancing action profile, including the description
and action
Parameters of the advanced ACL, including the ACL number, and matching rule
Parameters of the Layer 3 classifier, including the classifier name and the ACL and
Layer 7 classifier bound to the Layer 3 classifier
(Optional) Name and parameters of the connection parameter profile, including the

Parameters of the load balancing policy, including the load balancing policy name
and Layer 3 classifier bound to the load balancing policy
Object where the load balancing policy is applied (type and number of an interface)
pool, the Layer 3 classifier or the load balancing instance cannot be bound to the NAT address
pool.
if the IP address that is to be assigned to the outbound interface is the same as an IP address
