Dual Internet Connections ( Without Load-Balance)

Hello,

I have a Fortigate 90D (Firmware Version: 5.4.10,build1220) with the following configuration:

wan1 - connected to cable ISP

wan2 - connected to 4G ISP

I want all internet traffic to go through wan1, unless wan1 loses internet connection. In that case, I'd like to failover to wan2.

I added 2 static routes (1 for each interface ) and set the Administrative Distance of both to 10. I set the priority of wan1 to 0 and set the priority of wan2 to 10.

I then set a link-monitor with the following configuration:

ROUTER (link-monitor) # sh full-configuration
config system link-monitor
    edit "Wan1Failover"
        set srcintf "wan1"
        set server "8.8.8.8"
        set protocol ping
        set gateway-ip <gateway ip omitted>
        set source-ip 0.0.0.0
        set interval 5
        set timeout 1
        set failtime 5
        set recoverytime 5
        set ha-priority 1
        set update-cascade-interface enable
        set update-static-route enable
        set status enable
    next
    edit "Wan2Failover"
        set srcintf "wan2"
        set server "8.8.8.8"
        set protocol ping
        set gateway-ip <gateway ip omitted>
        set source-ip 0.0.0.0
        set interval 5
        set timeout 1
        set failtime 5
        set recoverytime 5
        set ha-priority 1
        set update-cascade-interface enable
        set update-static-route enable
        set status enable
    next
end

My hope here is that if/when wan1 goes down all traffic will shift to wan2. Once wan1 becomes available, all traffic will shift from wan2 to wan1. I largely followed this kb article: https://kb.fortinet.com/kb/documentLink.do?externalID=FD36151

Does this configuration satisfy these requirements?
