The workaround is really easy. Just configure a prober pool that has the GTM(DNS) that haves access to the F5 LTM devices:

-------
BIG-IP Global Traffic Manager (GTM) performs intelligent probing of your network resources to determine whether the resources are up or down. In some circumstances, for example, if your network contains firewalls, you might want to set up device-specific probing to specify which BIG-IP systems probe specific servers for health and performance data.

Also you may enable debug to better see which DNS device marks the VS as down:
