Make Azure Firewall Failure Logs available to Customers
Most Azure products and services have a firewall that can be configured to restrict access. A valuable feature of configuring firewalls appropriately and troubleshooting connectivity issues is being able to see which connection attempts are blocked by the firewall rules. This feature is very common on other commercial firewall products. Please add this ability so that users can review firewall logs for products like SQL Server and others.

Not having this feature is making it really hard for me to debug where in my network setup the problems are occurring. We don't need this on all the time, but would be excellent to be able to enable it during testing, validate, and then turn it off.
