    2. Allow ESP traffic through Azure Loadbalancer

      Azure Load Balancer, for external connections, can support only TCP (Protocol ID “6”) or UDP (Protocol ID “17”).

      It cannot support protocols like ICMP (Protocol ID “1”). As an example, also IPSec (and VPN using it) is not supported since you should open UDP port 500 (that is fine) and permit IP protocol numbers 50 and 51. UDP Port 500 should be opened to allow Internet Security Association and Key Management Protocol (ISAKMP) traffic to be forwarded through Azure Load Balancer. IP protocol ID 50 should be set to allow IPSec Encapsulating Security Protocol (ESP) traffic to be forwarded. Finally,…

    3. Support IP address in Backend Pool (Azure Load Balancer)

      Currently you can only include VMs or VMSS within an Azure Load Balancer Backend Pool.

      If we could choose an IP Address we would be able to load balance other resources hosted in Azure as well.

      Our use case:
      Load balance DNS queries (over udp-53) to Azure Container Groups (private IP).

    4. Delay load balancer rolling health threshold until first pass.

      We would like to implement an application-specific https load balancer probe for rolling upgrades. This always fails initial deployment because none of the VMs in the scale set have the application installed yet. It would be nice if the rolling upgrade threshold could be ignored until it passes for the first time.

    5. Azure load balancer probe service

      Currently you need to provide a custom probe service or use applications (e g SQL Always-On Availability Group) which has built-in probe services or use other services' ports (e g RPC 135) for the probe service. Would it be possible to provide a probe service application that you can install as a service on the nodes instead of having to write your own probe service? I have seen some C# samples of such TCP port probe services, which you could install as a service, but it would be better to have official in case there are improvements, updates or changes…

    6. Could we add VMs in Load balancer backend pool even they are in the different peered Vnets in the future?

    7. It would be great if you could use Azure Load Balancer to load balance on-premises VMs. This would make migration to Azure easier.

      It would be great if you could use Azure Load Balancer to load balance on-premises VMs. This would be useful for hybrid environments. This would also make migration to Azure quicker and easier. Third party load balancers (e.g. F5) are incredibly expensive. A low-cost cloud alternative would be a big win.

    8. Load balancer Probe Latest Status in Portal

      Is it too much to ask for a simple red/green light in the portal that has the latest status for the last probe attempt for each load balancer rule?

      This would save countless hours of debugging and it is a basic tool available from all firewall vendors.
