    1. WAF (Application Gateway) Listeners limit increase from 100 to 200

      We had issue regarding creating more than 100 listeners in Application Gateway, and found that there is a limitation of 100 listeners maximum which is very annoying because there is always scenarios where customers need to create multiple bindings for websites\domains, and then we need to create listeners for the same. I logged a case with MS and the response is not satisfying that MS can not increase limit from 100 to 200, MS will consider it in future.

      I had to create more listeners for my requirement which increased complexity in my architecture and cost as well.

      Please increase…

    2. Mutual SSL

      We ran into a limitation of the App GW today when the scenario required mutual SSL auth between the client IoT device and the backend server. Our Application Gateway always acts as a proxy to terminate incoming traffic and create new connections to our backend pools (SSL end to end).

      My team is looking for a way for the Application Gateway to include part of the client certificate in a header. Something that would be a unique to the client reaching out so that the backend could authenticate as needed.

      Please support this feature functionality!

    3. 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.

    4. Need ability to set Maximum file upload size as a property for V2

      Our hosted solution requires uploads larger than 2GB for some applications like uploading a large video. We need a user setting for the maximum file upload on the V2 AGW.

      The current documentation is also not clear. It says: The following table applies to v1, v2, Standard, and WAF SKUs unless otherwise stated. There are specific stated mentions of the 2GB limit for Standard and WAF and there is no specific limitation mentioned for v2.

    5. Set headers detailing TLS handshake

      Additional x-azure-{x} headers which provide details about the TLS handshake between the client and front door, such as the selected cipher, TLS version and key length. This will help provide operational insight about the client base.

    6. Application Gateway

      The notification for all the processes is generic. For example - if you are updating a listener or you are updating a Backend HTTP Pool, the notification is generic, and it is not possible to distinguish as to which process is taking how much time, or which process is currently in progress.

    7. "Azure Managed" SSL certificates for Application gateway for SSL offloading

      Please add the ability to use a Azure managed certificate for the application gateway for the use of SSL offloading. This feature would be nice so that we would not have to manage the certificate and it would auto update instead of us having to keep the certificate up to date.

    8. Allow the Front Door WAF to block/allow by the Socket IP, and not just the Client IP

      Currently, the option to block by IP on the Azure Front Door WAF only allows you to block by the RemoteAddr IP, which is the Client IP. We use a reverse proxy so need the ability to block by what is called the SocketIP in the Azure WAF Logs.

      Update your subscription limits documentation. Your documentation makes no mention of the single public IP address limitation. https://docs.microsoft.com/en-us/azure/azure-subscription-service-limits#azure-firewall-limits. Thanks.

    10. Allow Private DNS zones to have IP address from a vNet assigned rather than use Azure DNS Its

      This would allow for on-prem resolution for Private DNS. This would avoid having to stand up DNS proxy servers in each vNet all pointing to the same IP address

    12. Allow SSL/TLS configuration on Azure Frontdoor

      Allow option to configure SSL protocols and best practices, same as an application gateway on Azure front door service.
      Currently, Azure Frontdoor supports TLS 1.0 as well, there should be an option to select protocols as well as the cipher suite.

    13. Azure Front Door to support certificates from SwissSign CA

      We use SwissSign as our certificate vendor. These certificates are trusted by most devices and operating systems, incuding Windows 10 and Azure Application Gateway.

      When it comes to Azure Front Door they don't seem to be trusted.

      For us to be able to buy/use the Azure Front Door service we need for it to support our certificates that we use on our backend servers.

    14. Challenges in making AFD Work as a CDN for on prem resources

      We would like to use the AFD's WAFs capability and CDN for protecting our on premise farm

      We will need to create the service on AFD and have Backend access via an IP and Backend header
      Conceptually and by design the service should be able to do it
      Challenges:

      0. On a single IP we have many Names that are published in HTTPS only, a single certificate with SAN entry for all the names
      The IP address normally does not respond to any request and give a 403

      We have modified the IP to respond with 200 for HTTP
      but…

    15. Add custom error pages like 405(with TRACE method) at global level of application gateway V2

      Please add custom error pages like 405(with TRACE method) and other status code returned by appgw(without forwarding request to backend) at global level of application gateway V2, where customer can block other scenarios and return a designated URL to original client.
      Sometime customer has a requirement of completely removing 'Microsoft-Azure-Application-Gateway/v2' in response header, so please consider to add this feature in future.

    18. Even smaller "Dev" size of Virtual Network Gateway

      While the ability to set up a site-to-site tunnel between my local network and an Azure virtual network is a very great convenience, it's also quite the expensive convenience for the single-developer business. (If you have a VS Professional subscription, for example, you'll burn almost all of your included Azure credit on this alone.) This may be partly solved, at the cost of some overhead, by this request:

      https://feedback.azure.com/forums/217313-networking/suggestions/6169157-stop-start-virtual-network-gateway-to-don-t-pay

      ...but my first observation is that even the "Basic" size of VPN gateway is far more, at 100 Mbps and 10 S2S tunnels, than I actually require.

      How about a cut-down…

    19. Azure Application Gateway CPU Utilization Metric

      The Application Gateway offering provides quite a few useful metrics, but lacks some core performance metrics. Please, at a minimum, provide a metric and alert for CPU utilization of the instances behind an Application Gateway. When CPU utilization is not monitored at this level, it can affect the performance of dependent applications.

    20. Azure ApplicationGateways needs to log effective TLS-protocol-version of each call

      As Cloud Solution provider we need to know
      - which customers and
      - how many customers
      would be hit by an change of tlsMinProtocolVersion from
      TLSv1_0 to TLSv1_2
      Currently we are not aware of any possibility to get hold of
      effective TLS-version (with TLS-offloading within AppGateway)
