    1. Offers BGP prefix/route summary at Microsoft Enterprise Edge (MSEE) ExpressRoute routers

      There is an urgent business need to summarize BGP prefix/route at MSEEs before being propagate to its peers at remote sites i.e. Cloud Gateway Access (CGA) routers in relation to Express Route service (as there is vary limit of allowable prefix entry set at remote CGA routers i.e. default 20 in some case).

      This BGP prefix summarization helps reduce the need of large number of prefix entries to be broadcasted from Azure to CGA especially for business case that have large number of spoke VNETs (Hub and Spoke model) leveraging on granular address space of a large prefix.

      For example,…

    3. Azure DevOps Whitelisting

      Please create service tag for Azure DevOps Hosted Build Agents. I have been told that to allow hosted agent access through NSG - to my ASE's, I need to whitelist ALL external Azure IPs.. This is unaccesptable from a Security standpoint. Please address immediately

    5. Add additional Authorized CA for custom Certificate in Azure Front Door

      Actually it is possible to bring a custom certificate for custom domain name in Azure Front Door. Unfortunately, there is a restricted list of authorized CA (cf. https://docs.microsoft.com/en-us/azure/frontdoor/front-door-custom-domain-https). CA like Lets Encrypt (https://letsencrypt.org/) are not in the list. Is possible to add it ?

    6. Restrict Azure Bastion copy and paste by policy

      The Public Preview of the Bastion host allows copy and paste to and from the target host to the browser session and then the local machine. There is a requirement to restrict this capability to help reduce data loss. Perhaps this could be by policy?

    7. Add Effective Routes blade to Azure Firewall

      We are currently evaluating the use of Azure Firewall as our core firewall between on-prem and an Azure Hub/Spoke architecture via ExpressRoute.

      We need to be able to see what the effective routes are that Azure Firewall is using when we route all of our spoke traffic to it, and our on-prem traffic destined for the spokes to it as well. Currently, Effective Routes are only visible on resources with an associated NIC.

      Given that Azure Firewall is a PaaS network appliance, this is a critical feature for making it useful in our use case.

    11. Intermediate CNAME for custom domain on FrontDoor

      Custom domains on Front Door and App service do not work the same way.

      Custom domains on Front Door and App service do not check DNS records for custom domains in the same way.

      My usecase:
      - I have hundreds of clients with custom domains they have registered on their own (like myclient.com)
      - My clients use www.myclient.com to access our services
      - My company owns mycompany.com
      - I've asked them to add a CNAME like this: www IN CNAME client.mycompany.com
      - I've setup this record: client.mycompany.com IN CNAME mycompany.azurewebsites.net
      - We are using custom domains on App service with…

    13. Multi Tenant, Service Endpoint, vNet Peering, Subnet Whitlisting

      We have had a use case that could not be implemented due to the functionality not being available, We have a Multi-Tenant Alliance of Companies that require interoperability in regards to network access,

      Use Case:
      Tenant 1 :-
      Subscription,
      CosmosDB with Vnet with CosmosDB Service Endpoint

      Tenant 2 :-
      Subscription,
      VPN vNet with CosmosDB Service Endpoint

      We have managed to get both virtual network Globally vNet Peered via resourceID, however, cannot get the external tenant vnet subnet whitelisted within the cosmosdb due to it not being implemented yet.

      Confirmed with MS support to raise a Azure Network Improvement

    14. Add support for Azure Network Security Group Inbound rules to the Azure Application Gateway

      • In Azure, we CANNOT apply inbound NSG rule with destination public IP of APPGW to allow/block traffic to this APPGW. We known This is by design:
      Network security groups are processed after Azure translates a public IP address to a private IP address for inbound traffic, and before Azure translates a private IP address to a public IP address for outbound traffic.
      • Even for VM level public IP, we cannot allow/block traffic via inbound subnet level NSG with that destination public IP
      • The workaround I can think of is to deploy each gateway to dedicated subnet then…

    15. Azure Firewall with Just in Time Access

      With the latest just in time access support for Azure Firewall, DNAT rules are added when access is requested to the private IP. We have secure servers without public endpoints secured by JIT. As soon as a request is made to access port 3389, Azure Firewall NATs a port (13389) on its public endpoint mapped to our server. There is no notification of this happening at the time of the JIT request. It would be great to have a feature that would allow the DNAT setting to be disabled when requesting access through JIT.

    16. App GW with load balance should use single internal IP for single session

      App GW with auto-scaling enabled have Multiple internal IP for communicating hosted web service. The worst part is its communicating same session from client with Multiple IP internally because of load balance it has multiple machine for APP GW.

      e.g

      https://groups.google.com/forum/#!msg/pwm-general/miljylSaFjA/1qqhNS7lQgAJ;context-place=msg/pwm-general/za94hdmqPL4/tafnzLq5yUIJ

      We are using application with which
      NSG/IP restriction cannot be used because application is designed in such way it doesn’t allow same session from multiple IPs for security purposes and if we white list backend IP doesn’t makes sense because they always will be same from backend pools.
      Let’s suppose during some session of user some attacker hooks…

    18. Microsoft could be a provider of domain registrations.

      Currently we use Registro.br, Godaddy, 101Domain, Amazon Route 53, Google Domains among others for domain registrations. Microsoft could be a provider of domain registrations. It would be another service that would add to the cloud services already offered by Microsoft. Having everything centralized would be ideal, all in one invoice and customer loyalty.

    19. NSG Master Rule list

      NSG Master Rule list
      ================

      It should be possible to define the list of rules as a master list independent of NSG.
      Once defined, one should be able to use the rules with any NSG from the defined list.
      In most cases, we need to define the same rule again and again for different NSG.
      It becomes very difficult to maintain rules.

      There should also be an option to logically group the rules in the master rule list so that they are easy to search and apply.
      Maybe while creating NSG, all rules in the group of master rule list…

    20. Increase limit of custom domains per front door

      There is a limit of 100 custom domains per front door.
      This works well for apps that only require only a handful of domains, but SaaS applications often require it's customers to be on their own domain. This limitation currently prevents SaaS platforms using Azure FrontDoor.

      Alternative platforms such as Cloudflare or AWS Cloudfront already support a very large number of custom domains.
