Allow Traffic Manager Probes Through Azure Firewall
Traffic Manager is an essential component of any resilient deployment within Azure. Whether you have a multi-region behemoth, or simply want a simple way to activate DR instances should the primary go down, Traffic Manager has a configuration for you. One key component of Traffic Manager is its probes—by frequently checking the status of your application, Traffic Manager can make intelligent decisions about where to direct the traffic. As with all services, there are a specific set of IP addresses from which the probes will originate.
