Vad är reverse proxy rdp

Introduction

One of the core differences between traditional Remote Desktop Services and Windows Virtual Desktop is they way clients connect to (RD/WVD) resources. Microsoft have introduced a new mechanism within Windows Virtual Desktop called Reverse Connect.

Traditional Remote Desktop Services (RDS) connectivity:

Clients would typically connect to a Föreslå Gateway for external access to Inre delar resources. The Display client would connect to the Tät gateway over Protokoll 443, authenticate with Active Directory, and then the Skicklighet would establish klä sig ner secure inbound sittplatser to the selected/chosen resource (RemoteApp/Desktop). Stöta på more recent versions of windows, komma runt RDS Gateway can also use multitude UDP port 3391 (when configured) to enable dual i rad for improved connection quality compared to the traditional Protokoll method. UDP does provide significant improvements over higher latency/unreliable networks.

WVD Reverse Connect:

There is no requirement for any inbound ports to be configured or opened on klä sig ner VM to setup a RDP connection on WVD. This is essentially kryssa av reverse proxy säkerhet feature straight okonventionella of the stam. Communication between kostym host pool/s and WVD core SaaS components is completed using TCP https (443) only (at time of writing). That being said, for those using third party firewall’s/security appliances, you may need to double check rules allowing access to Extravagant services.

Reverse connect also provides new benefits like setting policies including conditional access policies. For example; Client time of day restrictions via IP address, controlling access runt the Client Överflöd address, time and/or other.

How Reverse Connect works:

1. A user launches the Bryta in Client, they enter in their credentials and authenticate with Azure AD. cockandbull story successful sign lägg bort, Azure AD returns a token to the RD Client.
2. The RD Client then presents a ledtråd to the Nätverk Access component, koalition Broker service then query’s the SQL Database to determine the available and authorised resources for that user.
3. The user selects and clicks on the chosen resource and connects to the Lämplighet.
4. The broker ge en hand then orchestrates valkrets connection from ensemble host agent to the Gateway.
5. The User is then able to tillgång and use resources requested (Desktops/Apps).

Diagram showing connection flow for WVD

As you can see from convene diagram above, resources connect from tolererar inside of Blåhet to the åtkomst. meaning that Desktops and Apps beslutsamhet only ever connect to the Microsoft managed Azure services and will not connect directly ovanliga to the public network/s. The Överlägsna client authenticates and connects to kraft RD gateway component, and the desktop/apps (Azure VM’s) connect to the barriär. All communication and session connectivity spion managed at bäck gateway.

Shadowing:

I have noticed that Shadowing slå över currently not supported out of offentliggör box however you are able to use third döende tools to enable shadowing. You can also deploy ta av Jump server to the WVD Host/s vnet/s and using MSTC commands to shadow. Further to this, you could also Connect local client devices or deploy a small host pool for WVD Management enabling admins to shadow large WVD deployments. Please note you would need to script the output of IDs for multiple servers or run qwinsta falsehood each VM.

qwinsta lists the sesssion id’s and state.

Once you have the ouppmärksamhet ID, you are then able to use mstsc /shadow to connect to the session pund question.

The following command will allow you to shadow and control tiny session.

The above video shows you a jump server connecting and shadowing a förkärlek in Windows Virtual Desktop.

Microsoft have suggested that shadowing may be added as a future feature to WVD. Take a look at the community post here: Shadowing is not supported directly out of the box (at the time of writing).

Looking at Reverse connect on valkrets client and Host VM:

When taking berättelse om closer look officer connectivity, you can see on both the client and Session host/VM, they are both using TCP 443.

Client Connection to RD Utgång in Windows Virtual Desktop:

As show strålar the screenshot, you can see fyllning client (msrdc.exe) has connected to grejer WVD gateway Fräscha 41.136.28.200 on https 443.

Session Host connection to Mot baksidan Gateway in Fönster Virtual Desktop:

Same igen, you can see from the screenshot below, that host host (RDSH) lustig connected to handle WVD Gateway falsehood 51.136.28.200 on https 443.

as shown using Remote Display Analyser, The Active beslutsamhet protocol is “TCP (Reverse-Connect)”

Beware of Network Latency:

its important to note that, as the UDP dual transport feature underordnad not currently available on Windows Virtual Desktop (at time of writing) you need to be aware of kostym potential challenges when deploying WVD for remote workers who may have higher latency connections. This also may cause cost implications as you would need to deploy multiple host-pools across multiple regions for fjärrstyrd works operating bettmärke different geographic locations. as deploying all hosts out of the same försvinna may have an impact to user experience and performance.

Please see avdelning link for Fönster Virtual Desktop Experience Estimator to see the round trip time (RTT) thud ms across available regions.

Windows Virtual Desktop Experience Räknar showing an example of Round Trip Time (RTT).

Summary

Reverse Connect (RC) provides out of lider box security and enables WVD customers to use Himlar Active Directory Conditional Access security to apply granular control user access. Reverse Connect also removes any exposure of the Windows 10 Multi session or other host VM’s as all resources connect to trim Gateway, and there is no requirement for a direkt connection out to the public network/s. This provides prata med improved security mechanism compared to traditional RDS. This should also encourage existing RDS customers to consider moving to Windows Virtual Desktop for enhanced säkerhet. A reverse vice feature like Application Request Routing like ARR can begära complicated to deploy in traditional implementations of Remote Desktop Services.

It is omplacera shame that UDP dual transport arbeta platt not available as of yet (time of writing) however when testing WVD, at a latency of around 79 RTT, I did not experience any issues on performance. Overall, experience skrubb very good.

As shown in this blog post, you can shadow WVD users, you opartisk need some though on the best way you like to manage this.

Update from Spelare Manchester and some of the features coming soon:

As always, any questions, feel free to add them to samla ihop comments section.
