2 ISPs, different LANS, redirecting traffic

[Gyom]

Hello,

I have A fortigate 100D with FortiOS 5.6.3

Today I have

[ul]

a LAN NETWORK

a DMZ NETWORK

An unique ISP connected to WAN1 all traffic going through WAN1[/ul]

I will have a second ISP soon which will be connected to WAN2

I want to have the DMZ still going through WAN1

And I want the LAN traffic going through WAN2 (the new ISP), and if the WAN2 link goes down, I want the traffic to go through WAN1 and going back to WAN2 when it goes up

How is this possible ? What do I have to configure ?

Thanks.

Hi Gyom,

Sorry to be so late to your post...probably not any help now, but this should be easily accomplished with policy routing or SD-WAN (either one I believe should work, but I have not done SD-WAN personally yet).

Here's an article about basic redundant Internet configuration with failover (not SD-WAN), but you would need to supplement it with the policy route for either the LAN or the DMZ traffic.
