    1. ARM Template support for NSG Flow logs

      Add support to configure NSG Flow logs using Azure Resource Manager template.

      The goal is to have Azure Policy to deploy NSG Flow Log configuration.

    2. Configurable back-end health check aggressiveness

      Related thread:
      https://social.msdn.microsoft.com/Forums/en-US/75cfb536-71f6-4c88-ac80-ec693f3e6229/azure-front-door-healthcheck-frequency?forum=WAVirtualMachinesVirtualNetwork

      Behind my frontdoor are two "back-ends", each consists of a single web app.

      For each back-end I have configured a health check with interval of 120 seconds. My expectation was that this leads to roughly 30 requests per hour.

      In reality, my application insights shows 64000 requests in the past 24 hours, that's more than 40 requests per minute! A live traffic log confirms this: I see health check requests come in almost every second...

      With the current behavior there is hardly any correlation with the configured "Interval" setting.

      It would be great if there was an…

    3. 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.

    4. 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,

    5. Allow configurable timeout period for Front Door

      Currently Front Door forces a 30 second timeout for backend requests. This can severely restrict the usefulness of the service in production systems. It would be great to have the timeout period configurable to allow for a longer period of time. My understanding is that the Azure Load Balancer, which sits in a similar space as Front Door, defaults to a 4 minute timeout period.

    6. Enable OWASP secure headers on Azure FrontDoor service

      Requesting Front Door be supporting OWASP secure headers (https://www.owasp.org/index.php/OWASP_Secure_Headers_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.

    7. Provide option to change which TLS versions are supported

      Provide option to change which TLS versions are supported - similar to the Azure App Service. This will allow for use of Front Door with PCI compliant apps.

    8. Support wildcard hosts in custom hostnames

      Many of current SaaS applications enable customers to select it`s own subdomain in order do have a personalized url.

      So let's say I own contoso.com and I let my customers select any subdomain (*.contoso.com) like:

      foo.contoso.com
      bar.contoso.com

      That's cool with a couple customers but when you have a large system it's not doable setup one by one, even that you can automate that.

      The ideal solution would be allowing custom hostname field to bind a wildcard domain, in this example *.contoso.com

      There's a similar idea for Application Gateway that has been for a while (https://feedback.azure.com/forums/217313-networking/suggestions/19527121-application-gateway-support-wildcard-hosts-in-lis)

    11. 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…

    12. 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.

    13. 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.

    14. 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.

    15. 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.

    16. 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.

    17. 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.

    18. Enable NSG Flow Logs for secured Storage Accounts

      At the moment, it's apparently not possible to use NSG Flow Logs with secured Storage Accounts, even if the exception "Allow trusted Microsoft services to access this storage account" is enabled on the Storage Account.

      It would be really helpful if you could add the Network Watcher this list of trusted Microsoft servies, so we can use secured Storage Accounts to store our NSG Flow Logs on.

    19. 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.

    20. 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…
