    1. 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)

    2. Allow Network Security Groups (NSGs) to Reference Application Security Groups (ASGs) From Different Location

      Remove the limitation of restricting Network Security Groups (NSGs) ability to leverage/associate Application Security Groups (ASGs) that are not within the same location of the target Virtual Network (VNET).

      This is especially important, to provide granularity and segregation/isolation in a hub-and-spoke networking model (i.e. VNetA-ASG1-to-VNetB-ASG1), in association with VNet Peering.

    3. Custom error pages in Azure Front Door

      As for Application Gateway, we need to be able to customize the error page displayed when the access to an url is refused by an ip restriction rule.

    4. Azure Application Gateway WAF Mode Increase Limit on SecRequestBodyLimit

      When we have the WAF set to prevention mode some of our HTTP post are denied with code 413.

      Request body no files data length is larger than the configured limit (131072).. Deny with code (413)

      Can you make these two settings configurable on the WAF?

      SecRequestBodyLimit
      SecRequestBodyNoFilesLimit

      Thanks
      Mark

    5. Confirguration of caching rules in Front Door

      Allow configuration of content caching rules similar to how Azure CDN (Akamai) and Azure CDN (Verizon). This will allow better support of leveraging Front Door with Azure Storage Static Websites where it is impractical to set cache-control on a per-item basis.

    6. Authentication to VPN Gateway using Azure AD

      Add option to authenticate to VPN Gateway using existing Azure AD accounts. For security reason there should be option to add a group of users allowed to use VPN.

      This should help to use Azure VPN Gateway by customers which not use local AD DS servers

    7. 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.)

    8. vpn gateway slow to create

      Why does it take upwards of 30 minutes to create a vnet gateway?
      If I am doing a PowerShell script or a CI/CD deployment, the whole world stops while the VPN takes 30-odd minutes to be initialised and start. Can this please be addressed?

    10. Application Gateway WAF: update to OWASP CRS 3.0.2

      The 'OWASP 3.0' (3.0.0) WAF rule set generates a lot of false positives, even on random base64 payloads. The only option is to disable many rules.

      2 examples which frequently trigger on SAML authentication exchanges are 932140 (https://github.com/SpiderLabs/owasp-modsecurity-crs/issues/671) and 941120 (https://github.com/SpiderLabs/owasp-modsecurity-crs/issues/675).

      OWASP CRS 3.0.2 reworked some rules, in order to reduce some of these false positives. Please support CRS 3.0.2 (either as an in-place upgrade for 3.0.0, or as a new option).

    11. 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.

    12. 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.

    13. Reorder the Listeners on the Application Gateway

      Recently I was in the need to register additional listeners to an App Gateway. The issue is that the rules and Listeners should be created (at least using the portal) on correct order and the portal don't have any options to change this order.
      As the process of update changes on the Gateway takes a few minutes, this type of change requires a few hours to create a new record, remove, add it again, create rules, etc.
      Using a pattern similar to the NSG where we define a value for the order would save a lot of time.

    14. Add a Network Security Group tag for Windows Update

      I'd like to be able to block all outbound traffic on my NSG but still allow windows update to work. This is difficult to do as the windows update depends on quite a few DNS names and the IP address of these apparently changes often.

      If I could specify an "Allow" rule for a service tag called "WindowsUpdate" or similar with a higher priority than my "DenyAll" rule this would acheive this.

      Add a feature that gives you an static IP regardless of what server you attach to it. That wat, if you have to migrate your server you keep your IP Address.

    17. Add App Service Virtual IP (VIP) as Traffic Manager endpoints

      When using the Alias Record Set of Azure DNS, it becomes an error if it is a domain name.

      App Service has a VIP, I would like an option to add IP instead of domain name.

    18. Make ASG independant of a VNET like NSG

      While it's possible to attach a NSG to multiple subnet or even different subnet in different VNET, it should be the same for ASG.
      Currently I can add machines only in the same VNET once a single machine had been added to the ASG.

      My usage : I've got different services I deploy in different vnet but identical usage just different environments. Then I have some shared resource such as nsg that are applied to these different instances and I wanted to add the different machines with same role to a single ASG instead of create one ASG/role/environment and just…

    20. Application Gateway Performance

      We have two large instances of Application gateway on our application which is a connected client application using long polling. When we did load testing, gateway starts to give 503 with just 10k connections whereas our back-end application just works with just 7 % CPU. When we raised ticket we got a response saying it is as per design. We did not expect this from Application gateway.
      Can you please let us know what is performance metrics of Application Gateway.
