Using the Dual WAN Wizard to Configure the WAN Redundancy Settings
Cisco ISA500 Series Integrated Security Appliance Administrator Guide 52
2
Choose the WAN redundancy mode and configure the relevant settings:
• Weighted Load Balancing: Distributes the bandwidth to two WAN ports by
the weighted percentage or by weighted link bandwidth. If you choose this
mode, choose one of the following options:
- Weighted By percentage: If you choose this option, specify the
percentage for each WAN, such as 80% percentage bandwidth for WAN1
and least 20% percentage bandwidth for WAN2.
- Weighted By Link Bandwidth: If you choose this option, specify the rate
limiting for each WAN, such as 10 Mbps for WAN1 and 5 Mbps for WAN2.
• Failover: Automatically directs all Internet traffic to the secondary link if the
primary link is down. When the primary link regains connectivity, all Internet
traffic is directed to the primary link and the secondary link becomes idle.
- Auto Failover to: Choose either WAN1 or WAN2 as the primary link. By
default, WAN1 is set as the primary link and WAN2 is set as the backup
link. You can also set WAN2 as the primary link.
- Preempt Delay Timer: Enter the time in seconds that the system will
preempt the primary link from the backup link after the primary link is up
again. The default is 5 seconds.
STEP 6 After you are finished, click Next.
The Network Detection window opens. From this page you can configure how to
detect the link failure.
Enter the following information:
• Retry Count: Enter the number of retries. The security appliance repeatedly
tries to connect to the ISP after the link failure is detected.
• Retry Timeout: Enter the interval value between two detection packets
(Ping or DNS detection).
• Ping Detection-Ping using WAN Default Gateway: If you choose this
option, ping the IP address of the default WAN gateway. If the default WAN
gateway can be detected, the network connection is active.
• DNS Detection-DNS Lookup using WAN DNS Servers: If you choose this
option, the security appliance sends out the DNS query for www.cisco.com
to the default WAN DNS server. If the DNS server can be detected, the
network connection is active.
