    1. Allow assigning and removing (and swapping!) reserved IP's on cloud services

      It is unfortunate right now you cannot just assign or remove reserved ips on a cloud service (or use them with cloud services in Affinity Groups).

      We have different cloud services for different environments and it would be great to be able to swap the reserved IP to the current production service. Technically it doesn't need to take the VIP from the cloud service it is swapping with rather just obtain a new (or use its old VIP) once the reserved IP is gone.

      Right now reserved IP's are extremely immobile.

    2. Want that VNet Peering can be created in another Directory

      Currently, VNet Peering between the different subscription there is a description that can be created. However, I checked , there was a need to be a separate subscription in the same directory.

      The scene in which Vnet Peering is utilized, the situation is considered overwhelming majority (such as the merger of the company, and integration of the system, etc for connection between VNet and VNet).

    3. Provide VNet to VNet Peering Alternative

      I am at a loss to understand why the only option to Peer VNets together is the extremely limited VPN Gateway (High Performance or otherwise), especially in the context of VNet Peers within the same Region. Why are we limited to the VPN GW Bandwidth for VNet traffic occurring entirely within Azure?

      I feel there should be an alternative option for Peering VNets together - at least if they reside in the same Region. Leave the VPN Gateway for external connectivity. This would open up a number of options in regards to Network Topology and make Azure flexibility more comparable…

    4. Adding another NIC to single NIC environment easily (IaaS v2)

      When adding another NIC to single NIC environment in IaaS v2, we receive the following errors:


      Update-AzureRmVM : Virtual machines with multiple network interfaces and virtual machines with a single network interface are not supported in the same availability set, also a virtual machine having a single network interface cannot be updated to have multiple network interfaces and vice-versa.
      StatusCode: 400

      ReasonPhrase: Bad Request

      So we have to delete the VM and recreate the VM with multiple NIC. Adding another NIC is typical scenario, though, we can't do that easily.

      Can you add a feature to add another NIC to…

      Hi there,

      You are now able to add a NIC to those VM sizes that support multiple NICs. The VM must be stopped (+deallocated) to be able to do this.

      Documentation here: https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-network-interface
      https://docs.microsoft.com/en-us/azure/virtual-machines/virtual-machines-windows-multiple-nics?toc=%2fazure%2fvirtual-machines%2fwindows%2ftoc.json#add-a-nic-to-an-existing-vm

      — Anavi N [MSFT]

    5. Allow Swapping of VIP with any two cloud service rolls (including reserved ip support)

      Using cloud services with VM's for development is currently a pain. If you don't use the staging/production setup under one cloud service you are out of luck if you want to do any sort of swapping.
      You should allow swapping the VIP's on any two cloud services (as long as they are in the same affinity group) as this would give far more development flexibility.

      This should work with reserved Ips (if assigned to one or both the web services) also.

      An alternative would just to make the ability to assign and move reserved IP's from one cloud service to…

    6. VNet Peering Limit - INCREASE

      With new concepts like Global VNet Peerings, Virtual Datacenter and Hub-Spoke Topology - VNEt peerings become more and more important.
      Please INCREASE the number of 50x allowed Peerings / Subscription/Vnet

      Many thanks in advance, you are doing a great JOB - keep it UP!

    8. Global VNET peering remote gateway and gateway transit support

      Remote gateways and gateway transit are currently not supported with global vnet peering. Is there a plan to support remote gateways in the global vnet peering feature to build a global hub-spoke topology over multipe regions?

    9. Allow us to control IP/DNS settings for VMs which are added to a Virtual Network

      Currently, private IP addresses are assigned in the order that you create VMs. For some more complex scenarios such as AD, this adds an extra planning step. It also makes it difficult to replace VMs which have a knows static address.

    11. Increase the limit on local netwroks per VNet

      The limit of 10 local networks per VNet is to constricting for companies that have multiple physical locations. Please please please increase that tohe LAN to VNet limit to 100 or something that eliminates the need to configure VNet to VNet connectivity.

    12. Allow Agent IP in UDR when using Forced Tunnel

      You can not add a UDR for the VM Agent IP when employing Forced Tunneling. This makes deployments fail (e.g. VMSS).

      Please allow UDR to the special VM Agent IP of 168.63.129.16

      Full error message:
      Failed to add route 'DirectRouteToVMAgent' to route table 'VmAgentIp'.

      Error: AddressPrefix 168.63.129.16/32 for route DirectRouteToVMAgent is not allowed because its in restricted address space.

    13. Want that VNet Peering can be created another Region in same Gio

      Currently, although it is possible to create a Peering between VNet within the same region, the same thing can be carried out also in the address space and subnets in VNet.

      When VNet Peering can be created another Region in Same Gio that becomes available, I believe that the network design and expansion becomes easy.

      I kindly ask for your consideration.

    15. Coexistence with Virtual Network Gateway and VNet Peering

      There is no problem if we create in the order of Virtual Network Gateway, VNet Peering. However, after creating VNet Peering, error occur when we attempt to create or delete of the Virtual Network Gateway.

      This is by design or bug ?

      Systems and networks that want to build on the Azure than you people think is complex. After VNet Peering is created, Virtual Network Gateway can create or delete, improvement we want to.

    16. Elastic IP Address to Enable Call to Other Web Services (eg Twitter, Enterprise)

      As more and more services will call other services in the cloud; many services require white-list of IP address for policy reasons. For example, Twitter or try to connect to other Telco Gateway. They cannot accept a IP Address Range (especially the whole Azure), as the IP address.

      Is there any plan to allow us to specify an IP address for a set of instance types (for example for these web or worker roles the IP address are xxxxxx)? In other words, one static IP address will be mapped to N instances of x role.

      I know Amazon EC2 allows…

      We have announced in TechEd 2014 that customers can reserve a public IP address and use it as their Virtual IP on the cloud Service.

    17. Make Virtual Network operations atomic on Portal and REST API

      Right now, the only operations about VNets on a subscription are SetVirtualNetworkConfiguration(xml) and GetVirtualNetworkConfiguration():xml.

      So when you need to add one Virtual Network, you basically download the whole XML, add a new configuration and upload the same thing. Therefore doing two things in parallel will result in a race condition, that's why the service blocks it and operations like 'delete vnet' do not happen in parallel on the Management Portal and give an error like:

      > An update to your network configuration is currently underway. Please try this operation again later.

      This also looks bad since many other services expose…

    18. Reserved IP added directly to an instance Virtual Machine

      support the capability to associate Reserved IP to every single instance of the Virtual Machine.

      when I add a reserved IP to a cloud service, the IP address matches the one reserved. When I do the same but add an instance IP address to a certain machine, it only adds a random public IP adress to the machine, and changes the name accordingly but this is not the same as your reserved IP address. This is not very useful when you want this machine to have a fixed public IP adress.

    19. Reserved Instance-level IPs (ILIPs/Public IPs - no firewall)

      Allow the reservation of Instance-level IPs.
      This will allow us to have an FTP server (which does not work with firewall) with an IP address that does not change every de-allocation.

      I have noticed a "Public IPs" section pop up in the Preview portal but no action buttons as of yet.

    20. ARM - Add address spaces to local network gateway without stopping active connections

      In the Azure Resource Manager portal, you must stop all active connections to the Local Network Gateway to add new Address Spaces for local networks or else the task fails. This causes downtime for all site to site VPNs to that gateway when a new address space must be added.
