I'm trying to run a PoC using fortigate VMs and a fortimanager hosted in Azure.

The fortigates are running and licensed but I cannot get them connected to the fortimanager no matter what I do.

The log in the fortimanager simply says deny request from the fortigate, I can't figure out why.

I'm not new to fortigate but I am new to fortimanager. Anyone have any ideas?

Hi @JClarkeP2U ,

What is the version of your FMG?

If it on latest version for all tree, it needs to allow below config for VM manage devices.

config system global

set fgfm-allow-vm enable

end

Have you tried to register from the Fortigate to the Fortimanager as the connection can be intiated 2 ways ? One from Fortimanager to the Fortigate or from the Fortigate to the manager and then the manager needs to just approve it.

Other than that as we are talking azure here better check the azure acl or security groups and Dashboard | Training Institute the training for Azure fortinet products and Fortimanager is free just as an extra tip.
