2nd Internet link

[yeowkm99]

Currently i have a fortigate 400E HA firewall with 1 WAN link for Internet and 1 MPLS link for WAN.

How can i accommodate a 2nd Internet link for redundancy in my firewall design so that if my 1st Internet link goes down, the 2nd Internet link will take over ?

the 2nd link will be from a different ISP.

How can we configure the 400E for WAN link redundancy

There are a few different ways to accomplish this.  SD-WAN is the most powerful option, but you can also do a simple link redundancy:
