    1. Application Gateway: Set DNS name for frontend IP in wizard

      When creating a new Application Gateway via the portal, you are prompted to set a frontend IP. This IP is then allocated a randomly generated dns name which cannot be changed. I'm guessing that most people do not want a random name for their public facing address.

      Please allow a name to be specified in the wizard and/or the name to be changed after the fact.

    2. HEAD requests to monitor health

      It would be nice to be able to use HEAD requests for health monitoring instead of full GET

    3. Headers to identify health monitoring requests

      My ApplicationInsights logs show all the health requests done by AG to monitor the health of the system.
      I'd like to have the possibility to recognize health requests through specific headers so that I can skip standard HTTP pipeline and immediately return 200 status code, without logging the request

    4. Allow Mutual SSL Auth on Application Gateway

      At the moment SSL termination is possible with Application Gateway but it doesn't cater for instances where client authentication is required (mutual auth). So if client auth is required, SSL needs to be passed through and terminated on each of the web servers. This increases load across the server farm and makes management of certificates more difficult since all certs need to be maintained on all servers. I believe this function is available with API Management but the additional cost is hard to justify if one doesn't require the other additional features. So having mutual SSL auth capability built into…

    5. Allow ACL on Application Gateway for IP filtering via X-FORWARDED-FOR header

      We have requirements from customers to restrict access via their company subnets. It would be very nice if the App Gateway supported not only the SSL offload but the ability to apply ACLs to allow or deny access via a defined network range using X-FORWARDED-FOR headers.

    6. Add "LocalSubnet" and "GateWay" tags to NSG.

      Our subnets rules always have a "Deny All" rule with a priority of 4096 to override the default rule with priority 65000 which allows all VNET traffic. We want to allow all traffic within the same local subnet and all traffic from the Gateway subnet. It would be handy to have tags for these subnets without having to resort to CIDR ranges for each subnet.

    7. Enable Multiple IP addresses for Azure Application Gateway

      Azure Application Gateway is a nice Service for Load Balancing Layer 7 HTTP and HTTPS traffic. Today, we can only attribute one IP address (Public or Private) to the Application Gateway Deployment. It is fundamental that a Load Balancer can support multiple IP addresses to provide flexibility (Based on many customers feedback)

      Support for both public and private IP at the same time is available on both V1 and V2 SKU. Customers can host multiple sites behind the same IP and port using multi-site listener today.

      Support for allowing same port on both public and private IP is in the roadmap.

    8. Allow both ExpressRoute and VPN Virtual Network Gateways on a single VNet

      We have several clients who require both a ExpressRoute Gateway to connect from their on-premises network, AND a VPN connection between the same VNet and another VNet (Either in the same subscription, or in a different subscription.

      An example is a client who wishes to use their subscription to host database servers that can then replicate certain data sets across to an other companies subscription via a VPN connection.

    9. Add support for pointing an Application Gateway backend pools to Traffic Manager profiles

      We'd like to start using URL-based routing for load balancing our web application, but we don't want to lose the auto-failover capabilities of our current TM profiles.

      Ideally, I'd like to point an Application Gateway backend pool to a Traffic Manager Profile (which in turn would point to Azure Web Apps configured in prioritized failover).

      Currently, there's no easy way to do this; if all pool members become unhealthy, you have to failover at the application gateway level to another application gateway. This requires a lot of unnecessarily redundant (and expensive) infrastructure for simply configuring failover for a backend pool…

    11. Application Gateway support for multiple IPs on backend DNS name

      We are using Docker on Azure. Therefore we have a single DNS name for all containers. It would be great to have support for this. Having a backend pool with a single DNS name like 'myservice.domain' having multiple A records (each one resulting in a separate backend server entry).

    15. Hello, please, make sure that you let the customers know about the charges and the instances operations when configuring the WAF

      Hello, please, make sure that you let the customers know about the charges and the instances operations when configuring the WAF. Apparently, the number of instances is what is making this service extremely expensive and none of this is mentioned during the setup. Also, please remove this from the security list because it is listed with free extensions such as IAASMalware, Monitoring etc. Thanks!

    16. Application Gateway needs to be faster and capable of greater transaction throughput

      Currently, Application Gateway is the only service on Azure that supports offloading certificates for SSL, but Application Gateway can take a long time to provision and update with changes, and is unable to handle the high stress levels imposed by some apps. Application Gateway should be quick to provision and update after configuration changes, and it should be able to handle large numbers of requests per minute (e.g., 6,000 per minute).

      We recently introduced changes which make any updates to Gateway complete in less than a minute. We are also working on reducing provisioning time. Regarding SSL offload performance – you should be able to increase the number of instances to scale out and handle increased load. 6000 new SSL connections per minute is not a lot and should be able to be served by a single Large instance. Please open a support ticket if you are seeing issues with performance at this scale.

    17. Use Public IP address with custom DNS label on existing Application Gateway

      The Application Gateway does not allow to get a public IP address assigned, for which the DNS label has been set.
      Error Message: "You can't choose a public IP address that has a domain name label specified."

      When using certificates that are registered on specific CNAMEs, you should be able to set the DNS label of the public IP address of the Application Gateway to match the CNAME.

    18. To improve portal user experience for Application Gateway configuration

      Application Gateway is a combination of backend pool, backend HTTP settings, listeners, custom probes and rules. Most of the time, to make changes, it is necessary to update more than one of the above mentioned settings (pool, HTTP setting, listeners, rules). Each settings are placed on different UI blades and takes nearly 3 - 10 mins to make single setting change getting reflected.

      Feedback: Make a Wizard kind of interaction that will enable to specify all desired setting changes at once, then let apply these changes in a single shot behind the scenes.

    19. Application gateway

      Hi MS team,

      Could you enable the 'Edit' option for the Listeners we are configuring in the Application gateway. This will be really helpful if we decide to change our certificate.

      Although we can do a workaround of deleting the listener and creating new one, but that needs some time investigating it, so I feel Edit option is a much better and easy approach for clients.

      Thanks,
      Thulasidas

    20. Make default ssl settings more secure (https://www.ssllabs.com gives only B-rate).

      When we deploy SSL listener with default settings, ssl configuration in not very secure (although acceptable for some services). Popular checker https://www.ssllabs.com gives just B-rate for this. You can check recommendations for example looking at report for our sample AGW deployed with default settings https://www.ssllabs.com/ssltest/analyze.html?d=tb-ag-dev.textback.io
