Automatic way to stop traffic from WiFi interface if WAN1 fails?

[ace5264]

Hello,

[ul]

WAN1 -> internet

WAN2 -> internet

Both have same AD and traffic flows over both to Internet

Have policy route such that Guest WiFi is using WAN2

Anyone know how to configure this such that Guest WiFi traffic is no longer going to internet if WAN1 goes down w/o manual intervention?

For example, my client doesn't want people to be able to use Guest WiFi if WAN1 fails b/c they don't want to share WAN2 bandwidth w/ Guest WiFi traffic. Is there a way to automatically stop Guest WiFi traffic, i.e. using link-monitor, SD-WAN, etc?

Using FGT 140D v5.6.x but could upgrade to v6.x if needed[/ul]

Thanks!

You should be able to use SD-WAN rules to accomplish this.  You can specify what interfaces are used for certain traffic.  I think this was added in 5.6.x, so you should have it without upgrading.
