6.4.2 (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,
----End

6.4.3 (Optional) Configuring Server Health Detection

In server load balancing, the SPU needs to detect the health status of each server. Therefore, the
SPU can determine whether to select a server for making load balancing decisions.

if the IP address that is to be assigned to the outbound interface is the same as an IP address
in the NAT address pool, the system displays the information that the IP address cannot be
set.
