Problem RDP to Azure Virtual Desktop through Azure Firewall

I'm following the learning document here:

https://learn.microsoft.com/en-us/training/modules/protect-virtual-desktop-deployment-azure-firewall/1-introduction

I can successfully RDP to the VM up until the point where I add the routing table, thus routing traffic through the Azure Firewall.

I've double-checked the network and application rules, and they are set exactly as per the document. I even added a catch-all network rule and an RDP rule to open up the firewall to all traffic, but I still can't RDP.

Network Collection Rules

Can anyone point me in the right direction as to what might be wrong?

Solution

  • To connect RDP connection to Azure Virtual Desktop through Azure Firewall Make sure to create the NAT rule in firewall like below:

    I have created Application and Network rule as same like below:

    Network rule:

    Now, to connect RDP create Nat rule like below:

    In the destination address, add the public IP address of the firewall in the Firewall -> Public IP section. Additionally, include the private IP address of the virtual machine in the translated address field like below:

    enter image description here

    To log in to the virtual machine, use the firewall IP address.

    Now, the virtual machine is successfully connected to the remote desktop as shown below:

    Additionally, ensure that you have added routes in the route table, and for the next hop address, use the Firewall private IP address. In the subnet, associate it with the hostVNet virtual network and subnet like below:
