I have a unique situation (I couldn't find anything that fit) and wanted to see if I could get some direction. I have the details below, let me know if you have any questions. Thanks in advance.
I have two internet connections coming into my Fortigate:
WAN1 - Internet Traffic
WAN2 - VOIP service
1. Internet should go out WAN1 and voice should go out WAN2.
2. If ISP on WAN2 drops out then it should fail over to WAN1 automatically, then come back to WAN2 automatically when WAN2 is restored.
3. If ISP on WAN1 drops out then internet traffic should route over to WAN2.
