We have a fortigate vm cluster in Azure which we like to split up into two standalone vm's.
Reason: Some restrictions in cluster config that can be solved using standalone vms.
I have managment connection via port4 and a dedicated IP (in the same subnet and a gateway in said subnet) to each of the vms in order to manage them.
Those information are in "config system ha".
When switching the HA configuration from "active/passive" to "standalone" I (obviously) lose the configuration of the HA Managementand Interface in "config system ha" and also the IP address in "config interface port 4" and therefore I lose the possibility to manage the vm over port4
While I know how to add the IP again to port 4 I am not sure how to add that specific gateway to that port4-subnet which was added by "config system ha - config ha-mgmt-interfaces - set gateway".
Does anyone know to do that so I can preserve port4 as my (now standalone) VM management port?
