Alteon Application Switch Operating System Application Guide
Firewall Load Balancing
Document ID: RDWR-ALOS-V2900_AG1302 681
Note: The clean-side Alteon must use the same metric as defined on the dirty side. For
information on using metrics other than hash, see Free-Metric FWLB, page 683
.
2. Create an SLB real server group on the primary clean-side Alteon to which traffic will be load
balanced.
The external clients are configured to connect to HTTP services at a publicly advertised IP
address. The servers on this network are load balanced by a virtual server on the clean-side
Alteon. SLB options are configured as follows:
Note: The virtual server IP address configured in this step will also be configured as a Virtual
Server Router (VSR) when VRRP is configured in a later step.
