FortiGate 101E WAN configuration

Hi @registracionesROS ,

What you can do:

1) Make sure that you have two default routes with wan1 and wan2 with the same AD;

2) Then you may use Policy Routes to redirect the traffic for VLAN01 and VLAN02 via wan1 and wan2, respectively.

Here is the article about how to configure Policy Routes on FGT:

Or, you can configure SD-WAN with two interfaces then set up specific rules for normal situation and failover for each LAN VLAN.
There are many documentation and instruction video available on-line. You just need to search with "Fortigate SD-WAN configuration step by step" or something like that.
The official FTNT's documenation is in the admin guide for your version of FortiOS like below:

Are you using SD-WAN?  If not why not?
