WAN Link Load Balancing
Document ID: RDWR-ALOS-V2900_AG1302 643
3. Enable WAN link load balancing.
4. Enable Direct Access Mode (DAM). Typically, you have two or more virtual server IP addresses
representing the same real service. On the return path, DAM ensures that the real server IP
address is mapped to the correct virtual IP address.
For information about DAM, refer to Direct Access Mode, page 200
.
Step 4a (Outbound Traffic)—Configure the Client Ports
Configure the redirection filter and enable the filter for link load balancing. This is required to
translate (NAT) the client IP address to the proxy IP address.
1. Define the WAN link load balancing redirection filter.
2. Enable WAN link load balancing for the redirection filter.
3. Add the link load balancing filter 100 to the outbound client port.
4. If you are configuring link load balancing for outbound traffic only, then go to Step 7—Apply and
Save Your Changes, page 645. The remaining steps in this procedure are used for load
balancing of inbound traffic only.
Step 4b (Inbound Traffic)—Configure Server Ports
For each real server connected to Alteon, assign a real server number, specify its IP address, and
enable the real server. Define a real server group and add the real server to the group.
1. Configure real server and create a group.
