    1. What was changed in Azure Loadbalancer - it prevents me from creating a second loadbalancer rule to a different backend pool?

      I have already several balancers that balance different type of requests to different backend pools - HTTPS to one AMQPS to another, WS to third one, etc..
      Today I realized, that I am not able to create another loadalancer rule without adding new publicIP. OK, I can add new IP address, but what about the already created and configured loadbalancers? How will they be affected? How long will they be able to operate, till they will stop providing outbound connectivity for my servers? Is there any refund for this type of harm?

    2. IPv6 should be default

      It's 2019. Globally routable IPv6 should be on by default, not some sort of advanced command-line only kludge requiring twiddling with load balancers and NAT the way it is now on Azure. See linode for simple and effective.

    3. application gateway monitor

      Application Gateways need more troubleshooting tools. The healthy/unhealthy logging is almost useless. We need to be able to initiate a ping/netcat from the AppGw to a host to verify connectivity. We also need to be able to see the DNS cache or see a log correlating incoming requests with outgoing requests by hostnames and IP addresses,

    4. Enable OWASP secure headers on Azure FrontDoor service

      Requesting Front Door be supporting OWASP secure headers (https://www.owasp.org/index.php/OWASPSecureHeaders_Project#tab=Headers)?
      Currently, our POC website using Azure FrontDoor fails many OWASP header tests, especially when Front Door would claim to protect against few OWASP attacks.
      Appreciate that these be on the FrontDoor roadmap in very near future.

      OWASP HTTP Secure Headers

      HTTP Strict Transport Security (HSTS)
      Public Key Pinning Extension for HTTP (HPKP)
      X-Frame-Options

    5. Expand vendor support for Azure virtual network TAP

      Allow Azure virtual network TAP to send collected data to a VM running Suricata, Snort, riverbed etc, not only the current list of vendors.

    7. Make TrafficManager more robust when there's a major outage

      We configured the TrafficManager to either point to deployement1 or deployment2, which live in different locations, depending on which is in the "prod" role (machines are allocated) or the "backup" role (machines are deallocated). Using the TrafficManager is attractive because the customer doesn't need to make any changes on their end; if we need to revise the TrafficManager to point to the other deployment, it's simple and straightforward to allocate the machines and run a few lines of PS code. However, during the recent extended outage in the South Central US, after allocating the backup machines, when we tried to…

    8. Traffic Manager Probe Success and Failure Logs

      Currently in the metrics for Traffic Manager, you cannot see a history of when probes passed or failed. You can only see an average of the probes over a period of time.

      Seeing the logs of when probes succeeded and failed for each endpoint could be helpful for troubleshooting. Particularly when you think a failover should have occurred, but it did not.

    9. Redirect to HTTPS

      Allow HTTPS only configuration to responds with 'redirect to HTTPS' when HTTP request is received. This will be very useful for the new static website storage accounts. Especially, when the wider premium 3rd party CDN is not needed.

    10. Add additional IP Protocols ls for NSG Rules

      Add the ability to add additional IP Protocols (i.e. ICMP, EIGRP, so forth) to an NSG rule. The only option today is TCP, UDP, or "". Currently to allow ICMP you have to allow any protocol "" and any port "*" in the rule instead of simply adding a rule for ICMP specifically. This inhibits the ability to meet security controls for isolation required in NIST SP800-53.

    11. standardize azure cdn offerings

      Currently I know that Azure provides CDNs from different vendors on the standard layer. There are three types of CDNs, as follows:

      S1 standard Verizon
      S2 standard Akamai
      S3 Standard Microsoft (Preview)

      Each offers different functions
      Https://docs.microsoft.com/en-us/azure/cdn/cdn-features

      But at the moment, our test has the best effect in the target area of ​​our products with Akamai's CDN effect, but
      Akamai does not support custom domain HTTPS features
      Microsoft does not support cache rules
      Verizon has all the above features, but the CDN effect is the least desirable in the target area of ​​our products.

      I am interested to know if…

      started  ·  Anton Kucer [MSFT] responded

      We are targeting to have parity across all standard SKU’s. Cache rules for Microsoft and HTTPS Custom Domain support are all targeted to be available later this year.

    12. improve application gateway rule description documentation

      When you will improve the documentation to include better descriptions at the rules? Having a rule with a description Rule 981312 doesn't help to know what it does! Enabling all rules have a huge impact on WAF performance and we need to know what exactly each rule does in order to fine tune it.

    13. More frequent NSG Flow log rollover, and consumption into Traffic Analysis

      It would be useful to have NSG flow logs consumed by Traffic Analysis more frequently than every hour (ever minute would be great!).

      Currently the delay is too long to be useful for real-time troubleshooting, and useful only for analysis retrospectively.

    14. 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.

    15. Application gateway should have the capability to store certificate in Azure Key Vault

      Currently Application gateway does not store certificate in Azure Key Vault. We believe that Application gateway should have the capability to do that. This will give customer more control over their certificate than saving it in Microsofts encrypted storage.

    16. Fix Virtual Network Gateway IKEv2 Security Logging

      Ok, so logging access to enterprise networks is a basic security control which we shouldn't be asking for in year 2018.

      If we deploy P2S/Virtual Network Gateway w/IKEv2/certificate authentication in its current state, we open our networks to the internet and have no idea who logs into it and from where. There are basically NO events logged for an authenticated user. In addition, the "Connection Count" doesn't increment. So If I have 100 users connect via IKEv2, Connection Count still shows 0.

      THIS IS A SIGNIFICANT SECURITY HOLE.

      Microsoft - this product shouldn't have been released, not in its current…

    17. VNET Gateway VPN Client should have easy way to refresh routes

      I noticed that you need to download the VPN client again if the peering changes on the VNETs associated with the gateway. Once the client has the routes you can tear down and recreate VNET peerings as often as you like. It would be nice to have an easy way to refresh the routes for your installed VPN client because I see customers wasting a lot of time trying to figure out why they can’t connect to vms. At least to have some warning to customers would be good when they configure vnet peering that they might have to reinstall…

      Hi Matt,

      Thanks for the feedback. The status of this ask is a bit complicated – it’s partially working, but partially in progress:

      1. For existing SSTP P2S VPN, there is no solution but to download the VPN client package again.

      2. For IKEv2 P2S VPN, it works by P2S client reconnecting to the Azure VPN gateway. Once they connect again, they will get the new routes. This will apply to changes in VNet address spaces (including VNet peering), newly added S2S/VNet-to-VNet connections, or new routes learned via BGP.

      3. The caveat for (2) is that it currently works on Mac and Linux, but Windows require a KB/Update that will be released shortly.

      We will provide an update to this item once the Windows update is available.

      Thanks,
      Yushun [MSFT]

    18. Allow paths in Application Gateway rules to be defined as regular expression

      Currently, Application Gateway rules support only path matches with a wildcard at the end of the string.

      For us it means to rework our routing strategy as the first part of our route is dynamic /<domain>/<controller> (eg. /sales/process). The controllers are shared among domains. Domains can be dynamically created, what disallow us to directly use the current feature to separate only 'process' controller to standalone backend pool.

      We would prefer to be able to define something like '/[a-z]]+/process.*' as a matching criterion.

    19. Make P2S (Point-To-Site) VPN work with Active-Active GW

      For running Production workloads in Azure we find that having a HA solution is important, and therefore using an Active-Active VPN GW is a must for us. Though we would also like to still use App Services linked to our custom vNet. At the moment this seems to not be possible as P2S VPN is not supported with a Active-Active GW.

      Therefore please make it compatible so we can connect App Services to our custom vNet and be able to communicate with onprem resources.

    20. Support for drainstop in Azure App Gateway

      Traditional loadbalancers support the following states, to facilitate performing maintenance on a system of multiple nodes gracefully:
      Enabled (All traffic allowed)
      Disabled (Only persistant or active connections allowed)
      Force Offline (only active connections allowed)

      When a application gateway node is "unhealthy" it only allows active connections. We are looking for a way to force a node into an "unhealthy" state.

      The currently supported method is to use a custom probe that checks a file/path. I would like a solution that doesn't involve making changes on the server going into maintenance mode.
