24. If you have two WAN links, use the WAN Redundancy page to determine how the two ISP links are used.
• Equal Load Balancing (Round Robin): Choose
this option if you want to re
• Weighted Load Balancing: Choose this option if you want to distribute the bandwidth to two WAN ports by the weighted percentage or by the weighted link bandwidth. The two links will carry data for the protocols that are bound to them.
– Weighted By Percentage: If you choose this option, specify the percentage of bandwidth for each WAN, such as 80% for WAN1 and 20% for WAN2.
– Weighted by Link Bandwidth: If you choose this option, specify the amount of bandwidth for each WAN, such as 80 Mbps for WAN1 and 20 Mbps for WAN2.
NOTE: The Weighted by Link Bandwidth option has the same effect as the 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.
