Redundant interfaces
Redundant interfaces, ensures that should your internet access be no longer available through a certain port, the FortiGate unit will use an alternate port to connect to the Internet.
In this scenario, two interfaces, WAN1 and WAN2 are connected to the Internet using two different ISPs. WAN1 is the primary connection. In an event of a failure of WAN1, WAN2 automatically becomes the connection to the Internet. For this configuration to function correctly, you need to configure three specific settings:
• Configure a link health monitor to determine when the primary interface (WAN1) is down and when the connection returns
• Configure a default route for each interface.
• Configure security policies to allow traffic through each interface to the internal network.
