    1. Load Balancer timeout set to 10+ hours per socket

      need longer time for 'keep alive' of socket. just like you can configure them with NGINX for example. We need min. 10 hours per socket.

    3. Load balancer probes to determine latency

      In addition to health probes, provide a probe to determine latency when pushing packets to the backend.

    4. LoadBalancer should support more than one IPv6 addresses on the internet frontend.

      At the moment the Azure load balancer supports only 1 IPv6 IP on the internet frontend.
      The IPv4 adresses where sold, the future is the usage of IPv6. But a loadbalancer can only handly one IPv6 Address???
      It minimum we should be able to terminate one IPv6 Präfix. Better that the LB can handle many dedicated IPv6 addresses.

    5. Azure load balancer health checks should have more configurable options

      The current Azure Load Balancer checks are very basic. They should be extended to allow
      * Custom headers added to HTTP checks
      * Auth headers on HTTP checks
      * Check returned content for a pattern
      * Allow POST rather than GET with customisable content
      * Accept other HTTP return statuses (for example, 3xx) as valid
      * TCP checks should allow configuration of Send/Expect strings
      * Maybe additional checks for such services as LDAP, DNS, etc

      As comparison, the popular HAProxy load balancer supports most of these capabilities.

    6. Could be possible LB TCP and UDP flows on all ports simultaneously when you're using an Public load balancer

      Unfortunately, HA ports configuration is available only for internal load balancers. It is not available for public load balancers.

    7. Cross-subscription VNet (Shared VNet)

      A virtual network that spans subscriptions. Multiple different subscriptions can deploy to the same virtual network in a region.

      If you are interested in this feature, please up-vote and add details about your company/scenario.

      We appreciate the feedback.

    8. Public IP Address Lock Period After Deletion

      It would be valuable to have a lock period for a public IP address that has been deleted from Azure. A use case would be if a user accidentally removes a public IP address from the Azure Portal, az cli, terraform, etc., a lock period of ~30 minutes is put in place so that the user is able to recreate the public IP address resource and bind to the previously deleted IP address.

      Hi Nate,

      Thanks for your feedback. In order to help reduce deleting dynamic Public IPs by accident, we added a feature in the Azure Portal that will prompt to ask customers if they want to reserve the IP address before deleting.

      In the future, we will default to Static Public IPs to prevent users from hitting this issue. However, we will not be building a lock mechanism.

      Hope this helps.

    9. Global Anycast Load Balancer

      Enable Load Balancer to serve multiple regions via a single global IP using anycast. GCP does this today. In Azure, you must use Traffic Manager and manually configure for the same effect. Also TM doesn't validate HTTPS while LB can.

    10. Azure Loadbalancer must delete unhealthy VM of Azure VMSS

      I have create Azure VMSS behind Public Azure Std LB with HTTP based Health Probe. Azure Loadbalancer is working as per expectation. But If VM is unhealthy then it must be deleted or re-provisioned. So that machine can attain healthy state again.

      I’d like to ask you for more feedback on this request please. Load Balancer doesn’t control the VMSS. I think what you’re looking for is a way for VMSS to replace any instances with a LB health probe status of 0. I’ve reached out to VMSS team to get their input. LB is likely not the right place to do this.

    11. Built-in policy to audit VNet rules / usage of service endpoints

      Built-in policy to audit VNet rules / usage of service endpoints

      More and more services in Azure have the ability to use service endpoints (e.g. Azure SQL Database, Azure Storage Account, Azure Data Lake, ...)

      This is necessary to fulfill IT-Security requirements and helps to restrict the access to critical Azure service resources from only specific virtual networks.

      At the moment there is no built-in policy / initiative to audit the usage of these service endpoints.

      Would be possible provide a built-in policy / initiative for this case?

    12. Allow VM's to have multiple Public IP's with a single private IP

      We should be able to attach multiple public IP's to a single NIC without having multiple private IP's.

      It is very difficult to configure 3rd party firewalls needing a 1:1 between public IP's and private IP's as far as routing rules go.

    13. Utilization

      I need to get the bandwidth utilized per month with cost only for internet traffic in/out from datacenter (**Excluding the VM to VM traffic in/out). It will be helpful for Firewall,WAF,SIEM kind of implementation analysis (if historic usage available for last (1hr,24,7days,30days,,matrix)

    18. RST packet is sent from probe of load balancer.

      The probe use RST to disconnect a TCP connection that established 3 way handshake. If I use an software to monitor some paket, the software will detect some errors by RST paket. I hope we can use FIN sequence to close the TCP connection.

    19. Monitor Application Gateway Load

      Provide a way to monitor Application Gateway CPU/Memory in order to track load. It's hard to know only based on current access/http errors when the WAF is under heavy preasure and we need to scale it up.

      There is no plan currently to offer these system level metrics for Application Gateway Standard (V1). However, we are planning to offer more observability with our new Autoscaling version (V2) of Application Gateway/WAF. We already offer Capacity Units as a metric which gives you a sense of the traffic load on your Application Gateway. More are planned for V2. Please send in your specific feedback via https://aka.ms/ApplicationGatewayCohort

    20. VNet is difficult to manage

      Splitting a resource group for each service makes it hard to connect the service to the network.

      I offer VNet peering free of charge or demand network service globalization
