Configuring the WAN Redundancy
Cisco ISA500 Series Integrated Security Appliance Administrator Guide 115

STEP 4 Click Save to apply your settings.
STEP 5 To check the connection of both links at regular intervals after you enable the Load
Balancing mode, you first need to enable the Link Failover Detection feature. To
configure the Link Failover Detection settings, go to the Networking -> Link
Failover Detection Settings page. See Configuring the Link Failover Detection,
page 117.
Load Balancing with Policy-based Routing Configuration
Example
Use Cases: The customer has two lines, one is a cable link and another is a DSL
link. The majority of trafffic goes through the cable link since it has larger
bandwidth, and the rest traffic goes through the DSL link. As lots of secure
websites (such as bank, or online shopping) are sensitive to flip flop the source IP
address, let the traffic for https, ftp, video, and game go through the cable link.
Configuration Tasks:
• Configure a configurable port as the secondary WAN port (WAN2). See
Configuring the Secondary WAN, page 104.
• Connect the cable modem to the primary WAN port (WAN1), and connect
the DSL modem to the secondary WAN port (WAN2).
• Enable the Weighted Load Balancing mode, and set the weighted value of
WAN1 to 80% and the weighted value of WAN2 to 20%. See Loading
Balancing for WAN Redundancy, page 113.
• Enable the Policy-based Routing (PBR) feature, and configure PBR rules so
that the traffic for https, ftp, video, and game is directed to the WAN1 port.
See Configuring Policy-based Routing Settings, page 134.
• Enable the IP Bandwidth, Service Bandwidth, and WAN Bandwidth reports
so that you can check the WAN bandwidth usage by IP address, service,
and time. See Reports, page 85.
