Or you just want to improve your skills Udemy has some great courses for a reasonable one-time fee. Then you need a policy and a static route on both firewalls. On fortigate 2 you do the reverse with 10,11,12 subnets in local and subnet for vlan 4 in remote. If you are new to FortiGate firewalls, as I recently was. In your case fortigate 1 would have the vlan 4 subnet in the local field and vlan 10,11,12 subnets in the remote field. In the popup that appears you will need to check and delete the referencing configuration.Īfter removing all of the referencing configurations the Delete button will be available.

The easiest way to find configuration referencing your interface is to click on the number in the “Ref” Column This is confusing if you create an interface by mistake and want to delete it as FortiGate has automatically created some additional configuration referencing your new interface, blocking deletion. You need to remove this other configuration(s) before you can delete the interface.

The reason the delete option is not available is that there is another configuration referencing it. It would be better if the button was active and just gave you a pointer why you can’t delete it just yet. I personally think this is one thing, especially if you are new to FortiGate firewalls that is not as clear as it could be in the GUI. After selecting the VLAN interface the Delete button at the top of the screen was greyed out with no clear explanation as to why. After creating a VLAN interface by mistake I was a little confused about how I could remove it. I recently started using Fortinet FortiGate firewalls for the first time.
