    1. Support for HTTP to HTTPS redirection for Application Gateway

      When using an Application Gateway to provide SSL offloading for applications hosted on IIS / IaaS, there is no native option to redirect HTTP requests to HTTPS. Without redirection or a listener on 80 for the host name, users receive a 404 response. This leads to developing a more complex network topology to handle inbound HTTP request to the host name.

      Possibly allow for an additional option on a listener, that will allow for returning a redirect HTTP code with the proper HTTPS URL, creating a clean/seamless experience for the end user.

      • Enable Multiple IP addresses for Azure Application Gateway

        Azure Application Gateway is a nice Service for Load Balancing Layer 7 HTTP and HTTPS traffic. Today, we can only attribute one IP address (Public or Private) to the Application Gateway Deployment. It is fundamental that a Load Balancer can support multiple IP addresses to provide flexibility (Based on many customers feedback)

        • Application Gateway WAF Rules and Concerns

          I understand that AAGs WAF is in preview currently. We have the following concerns and would like to know what we should expect when WAF is GA.

          It currently appears that all REST calls must contain certain headers (Accept, User-Agent). This causes problems with many 3rd party packages that make REST calls but are not configurable to adjust the headers before being sent. Is the expectation that when WAF is GA that these headers will still be required?

          We currently have any PUT requests (with the necessary headers) rejected by the WAF:
          Access denied with code 403 (phase 1). Match…

          • Either add Point-to-Site SSTP VPN clients for Mac/Linux or enable other connectivity options

            With Azure trying to attract more than just Windows devs, we need to be able to VPN using non-Windows platforms for point-to-site connections.

              Thank you for your suggestion, and all of the support it has received. We understand this is a major pain point for a lot of our customers. We are currently working on enabling non-Windows clients to connect to Azure.

            • Support IPv6 Throughout the Azure Platform

              IPv6 has been a standard for years and ISPs are starting to roll out native IPv6 stacks to consumers. The time is now to support IPv6.

                As noted by SamirF, Azure now offers load-balanced, dual-stack (IPv4+IPv6) Internet connectivity for Azure VMs. This native IPv6 connectivity (TCP, UDP, HTTP…inbound and outbound initiated) all the way to the VM enables a broad range of service architectures. IPv6 for Azure VMs is available now in most Azure regions. Data transfers over IPv6 are billed at the same rates as IPv4. For more information, please visit this Overview of IPv6 for Azure Load Balancer: https://azure.microsoft.com/en-us/documentation/articles/load-balancer-ipv6-overview/

                We realize load-balanced Internet connectivity is just the first step of what is implied by this suggestion & comments and support for more scenarios is under development.

                Please add suggestions for specific scenario/service you need IPv6 enabled to help guide our prioritization and work?

                Many thanks,
                The Azure Networking IPv6 feature team

                • Provide multi-factor authentication capabilities in VPN client

                  The ask is pretty self-explanatory.

                  We want to host sensitive data in Azure VMs and enable connectivity only via P2S VPN.

                  Today, the VPN client only requires having the cert to gain access the Azure Network. As the cert can easily end up in the hands of someone who shouldn't have access to it...it's not very secure.

                  For MFA, integration with PhoneFactor would be cool. At a minimum, the VPN client should require a username/password in addition to requiring the cert.

                      • Allow modifying NS records in apex of DNS zone

                        We need to be able to modify the NS records in the apex of a domain hosted by Azure DNS.

                        In the wake of the DYN DNS DDoS, a lot of large websites are adding multiple independent DNS providers to reduce the impact of a single DNS provider being taken offline.

                        However, you cannot do this if you use Azure DNS, because Azure does not allow modifying the NS records in the apex of your zone.

                        Modifying these NS records is possible in Route 53 and Google Cloud DNS, and it is because of the lack of this functionality that…

                                Allow secondary NICs to have public IPs. We're trying to deploy Palo Alto Network appliances as a VPN endpoint and it requires dual-NIC each with a public IP address. PA's reference architecture uses a NAT server to provide a second public interface. This is not idea since we have to manage multiple servers and routes. The completed multi public IP feature allows multiple public IPs on the same NIC. We're looking for public IPs on multiple NICs.

                                    Thank you for your suggestion. We currently have something in the Portal called “Resource Health Check” under “Support + Troubleshooting” within your Gateway. It will check the health of your Gateway and try to determine the cause of an unhealthy Gateway. We understand how important this is, and are working on further improvements to monitoring and diagnostics.

                                    Thanks,
                                    Bridget [MSFT]

                                  • Monitoring of ExpressRoute

                                    I want to be alerted, when my metered ExpressRoute is reaching a certain limit (that it is cheaper for me to go with unlimited model).
                                    Overall no monitoring supported to verify if peering is up, how much inbound and outbound traffic is going through the ExpressRoute/Virtual Network Gateway.
                                    The ExpressRoute is critical and therefore its state needs to be monitored.

                                      • When Network Security Group applied for Subnet or changes writes this Azure Log.

                                        We need records in log when someone apply or remove NSG for subnet. Also it would be great to log changes to NSR rules.

                                        • Azure Secure DNS for protection against malware and other unwanted content

                                          Create a Secure DNS service that can be used by Enterprise DNS servers and report and block suspect activity from clients. The solution should be based in Microsoft Azure, but should also be integrated with either Microsoft OMS og Windows ATP service.

                                          All log files collected from Enterprise DNS servers should be forwarded to the Azure Secure DNS service (https://blogs.technet.microsoft.com/teamdhcp/2015/11/23/network-forensics-with-windows-dns-analytical-logging/)

                                          Examples:

                                          • Allow adding of web apps from other subscription to traffic manager

                                            Currently it is not possible to add web apps from different subscriptions (e.g. EU and US deployment in different enterprise accounts) to the same traffic manager configuration, not even as external endpoint via Powershell.

                                            This seems to be an artificial restriction as it prevents endpoints with "azurewebsites.net" in the domain name, but using a CNAME to change this domain name works (nasty work around).

                                              Thank you for the feedback. We are improving the cross-subscription support in the Azure Resource Manager (ARM) API for Traffic Manager, in two ways:
                                              1 – The current restriction on using websites as ‘external’ endpoints has been lifted
                                              2 – Web Apps from different subscriptions can be added to a Traffic Manager profile, so long as the account being used to set up the profile has read access to the web app (which can be configured using the ARM RBAC rules)

                                              These changes are in the ARM API for Traffic Manager only. The old portal / ASM API is unchanged.

                                              We’ll be publishing further guidance on this topic in the future.
