Hello everyone,
Please i need advice on link redundancy configuration:
Fortigate 60E firmware v6.4.8
Wan1 -> Main ISP
WAN2 -> Backup ISP
Redundancy is working ok i think; when WAN1 fails, WAN2 becomes active BUT when this happens i lose all external services like mail server, nvr's, web services, all of these tied to my main ISP Public IP Address which at that moment is down.
Is there any configuration i can make to passthrough all requests made to my main ISP public address (Down) to my backup ISP(Active)?
Appreciate the help

No. Not possible unless you own your own public subnet with ASN, and advertise the subnet to both ISPs via BGP. ISP2 never routes packets destined to ISP1-provided IPs/subnets toward you over their circuit.
