percentage of bandwidth for each WAN, such as 80% for WAN1 and 20%
for WAN2.

amount of bandwidth for each WAN, such as 80 Mbps for WAN1 and 20

Weighted by Percentage option. However, it provides more percentage
options than in the Weighted by Percentage field.
•Failover: Choose this option if you want to use one ISP link as a backup. If a
failure is detected on the primary link, then the security appliance directs all
Internet traffic to the backup link. When the primary link regains connectivity,
all Internet traffic is directed to the primary link and the backup link becomes
idle.
-Select WAN Precedence: Choose one of the following options:
Primary: WAN1; Secondary: WAN2: If you choose this option, WAN1 is
set as the primary link and WAN2 is set as the backup link.
Primary: WAN2; Secondary: WAN1: If you choose this option, WAN2 is
set as the primary link and WAN1 is set as the backup link.
-Preempt Delay Timer: Enter the time in seconds that the security
appliance will preempt the primary link from the backup link after the
primary link is up again. The default is 5 seconds.
