R3204P16-HP Load Balancing Module Typical Configuration Examples-6PW101

NAT-mode load balancing configuration

example

Network requirements

The servers are in the private network and need to provide services for the users in the external network.

Configure NAT-mode load balancing on the LB module installed on the A7503 to achieve load

balancing between the private servers, which have a public IP address assigned to allow external users

to access.

Configuration considerations

1. Configure the A7503 switch—Assign the ports that connect the internal network to VLAN 200,

and assign the interface that connects the external network and the 10GE interface that connects

the LB module to VLAN 110 and VLAN 10.

2. Configure the LB module—Configure the 10GE interface that connects the A7503 switch as a

Layer 3 interface and configure the routes.

3. Ensure the reachability between the A7503 switch and the LB module, the internal servers, and the

external network.
