    1. More public IPs on Azure Firewall

      At the moment you only have the possibility to have 1 public IP on Azure Firewall. When this IP is used for ex. access to AD FS WAP behind Azure Firewall, then you are not able to host other services on port 443/tcp behind Azure Firewall that needs to be accessible from the Internet.

      Please provide the option to add additional public IPs to Azure Firewall.

    2. X-Forwarded-For from firewall should be sending the external IP of the incoming connection.

      X-Forwarded-For is being overwritten by the firewall, so our internal servers cannot check the external IP of the incoming connection.

      This is a requirement of both business logic and PCI requirements, and the firewall should be sending the external real IP instead of its own IP to the internal servers.

    3. Add ASG support on Azure Firewall

      Currently it's not possible to utilize ASGs in the Azure Firewall which limits the possibility of having an autoscaling environment and at the same time limit the network access to only what is necessary by specific resources.

      If deploying new resources and adding them into existing ASGs, it would be beneficial to be able to utilize ASGs as source/destination in Azure Firewall as well to remove the need of having to configure IP specific rules each time a new resource is deployed.

    4. Disable source NAT on incoming sessions on Azure Firewall

      Hi,

      As far as I can tell, source NAT is applied to all incoming sessions crossing a destination nat-rule on the Azure Firewall.

      It would be great if there was an option for this implicit source NAT to be disabled. Doing so would allow internal Azure VMs to see the real public IP address of the system making the incoming connection.

      The Azure Firewall deployment docs state that a default route should be set on the host's subnets pointing to the Azure Firewall - so source NAT should not be necessary for (public) Internet IP addresses to be routed successfully…

    5. Remove requirement for public IP on Azure Firewall.

      Our organization requires access to Azure cloud only via VPN for internal users. We would prefer to use the Azure firewall however currently a public IP is required. The requirement for a public IP should be eliminated as from a security perspective, this is unacceptable if the firewall is used for internal traffic only.

    6. Azure Firewall

      Please add the ability to protect against inbound traffic from the public internet in addition to its present ability to protect outbound traffic. If this is going to be offered as a true SaaS 'Firewall' solution, I believe this should have that true firewall protection for incoming traffic (protection against common attacks, layer 7 packet inspection, etc.)

    7. Logs to Appear in Log Analytics Near Real Time

      I have setup Azure Firewall wit Log Analytics. What would be useful is if the logs could get shipped near real time to Log Analytics. Experiencing about a 10 min delay.

    8. Add Azure Firewall compatibility with Application Gateway

      I have an architecture with multiple subscriptions, virtual networks and connectivity to on-premises. In the hub subscription we use(d) Azure Firewall to filter network traffic between networks.

      It appears that Azure Firewall cannot be used in conjunction with Application Gateway, as (apparently?) the health probe traffic is not routed correctly and backend status is deemed as "unknown" even though everything is healthy. Microsoft Support confirmed that this is currently unsupported.

      This prevents us from using ready made PaaS solutions (App GW) in order to publish services running in Azure. At the same time, we consider network security a critical matter…

    9. Add Effective Routes blade to Azure Firewall

      We are currently evaluating the use of Azure Firewall as our core firewall between on-prem and an Azure Hub/Spoke architecture via ExpressRoute.

      We need to be able to see what the effective routes are that Azure Firewall is using when we route all of our spoke traffic to it, and our on-prem traffic destined for the spokes to it as well. Currently, Effective Routes are only visible on resources with an associated NIC.

      Given that Azure Firewall is a PaaS network appliance, this is a critical feature for making it useful in our use case.

    10. Azure Firewall with Just in Time Access

      With the latest just in time access support for Azure Firewall, DNAT rules are added when access is requested to the private IP. We have secure servers without public endpoints secured by JIT. As soon as a request is made to access port 3389, Azure Firewall NATs a port (13389) on its public endpoint mapped to our server. There is no notification of this happening at the time of the JIT request. It would be great to have a feature that would allow the DNAT setting to be disabled when requesting access through JIT.

    11. Azure firewall application rule does not support non-http80/http8080/https443 protocol, for example SMTP. Please add the new feature.

      In order to inspect access to smtp.office365.com through Azure firewall, and leverage target FQDN in application rule, please add SMTP protocol support since currently AFW does not support non-http80/http8080/https443 protocol.

    12. Support for network rules with dns name or application rules with packets other than http/https.

      Support for network rules with dns name or application rules with packets other than http/https.

      For example if my service require access to SFTP or SMTP outside my organization I would like to open a rule with its domain address name and port (TCP_22 or TCP_25 respectively).

      Thanks for the valid suggestion. Your feedback is now open for the user community to upvote which allows us to effectively prioritize your request against our existing feature list and also gives us insight into the potential impact of implementing the suggested feature

    15. Add what network rule is matched in logging

      The Network rule log does not include the matching rule name like it does for Application rule log. In the Application rule log it reads "Action: Allow. Rule Collection: collection1000. Rule: rule1002" in the message, but Network rules end at "Action: Allow". It makes it hard to troubleshoot firewalls, and know what rule is causing the issue. It also makes it hard to introduce the firewall into an existing environment where you have to start with an allow all rule because you do not know if what rules are getting matched.

    16. Integrate Azure Firewall with Just in Time VM Access

      I'd like to get rid of my NSGs but need to keep them around for Just in Time VM Access. It would be nice if that feature integrated with Azure Firewall instead of just the Network Security Groups.

    17. Azure Firewall - Allow rules for any port on FQDNs

      Currently there is no option to allow connections to FQDNs through the Azure firewall unless the connection is on port 80 or 443.
      This means that we can't secure connections from IaaS VMs to services such as Service Bus which requires ports 9350-9354.
      Currently the only other alternative is a 3rd party NVA.

    19. Azure Firewall - managed backup function

      Azure Firewall is a managed service but as of now is missing some critical operational functions like backup/restore and audit trail. Please enhance the service to automatically backup configuration (i.e. rules) and allow for restore into existing or a new instance of the Firewall. Also, enable some reporting capability that will show a history of configuration/rule modifications (add/delete/update)

    20. Why does it take 5 minutes+ to save changes to Azure Firewall?

      Is it possible to make it quicker to save changes to Azure Firewall? A simple rule change takes upwards of 5 minutes to complete.
