![]() ![]() Let’s assume we enable Azure Bastion for a Virtual network which is already peered with another VNet. According to Microsoft’s recent announcement, Azure Bastion is now supporting VNet Peering. Once Azure Bastion service is enabled in a virtual network, remote access (RDP/SSH) will be available for all the virtual machines in that particular virtual network. This is similar to using a jump-server to connect to resources in the remote network but instead of the traditional RDP method, it is using browser-based secure HTTP connectivity.Īzure Bastion deployment is per virtual network. However, it required additional configuration at the network level.Īzure Bastion is a solution that we can use to access Azure VM securely without the use of public IP addresses or VPN connectivity. It is secure than the public IP address method. If we have VPN or Express Route connectivity to Azure, we can connect to virtual machines using private IP addresses. ![]() ![]() This method provides easy access but not a very secure method. In this way, the virtual machine will have a public IP address (static or dynamic) assigned to it, and RDP or SSH service ports will open to the internet via NSG. If we need to access an Azure VM using RDP or SSH, most of the time we access it using the public IP address.

To proceed,ġ) Click on Connect on Azure Bastion page.Ģ) Then fill in the relevant info such as IP address, port, username, and password.ģ) In the end, click Connect to initiate the connection.Ĥ) As expected I was able to connect to the VM (10.15.0.4) using an IP-based connection.ĥ) I also test with VM running on UKSVnet1 (UK South) which has IP address 10.75.0.4 and I was able to connect without an issue.Īs we can see above, the IP-based connection with Azure Bastion is working as expected. To test the connectivity, first I have chosen a VM running on EUSVnet1 (East US) which has IP 10.15.0.4. If it’s set to Basic SKU, click on the drop-down and select Standard.Ħ) Then from the feature list select IP-based connection.Ĩ) Once the changes are applied, we can see a new connect setting on the Bastion page. Virtual machines in the remote network for testing Configurationģ) From the list, click on the relevant Azure Bastion deployment.ĥ) Under the Tier, make sure it is using Standard SKU.A step-by-Step guide to set up this environment is available on I have deployed the Azure Bastion service on the hub virtual network ( BASVnet1). Both Spoke virtual networks will have Global VNet peering with Hub virtual network. EUSVnet1 & UKSVnet1 are Spoke virtual networks and BASVnet1 is the Hub virtual network. For the connectivity, we will be using the hub-spoke network topology. Each resource group will have its own Azure virtual network. Here I have created three resource groups in three different Azure regions. For this demo, I am using the following setup. If you are using an express route or site-to-site VPN, those networks also should be reachable from the hub network. All other networks will connect to the hub network. Ideally, it should follow hub-spoke network topology and install Azure bastion in the hub network. Azure Bastion Deployed – You need to have already deployed the bastion with the relevant connectivity.Prerequisitesīefore we move forward with the configuration make sure you have the following, In this blog post, I am going to demonstrate how we can enable IP-based connection on the existing Azure bastion. ![]() That will provides a seamless RDP/SSH access experience to Azure and Non-Azure virtual machines. Normally when we need to connect to VM via Azure bastion, we use the VM page to connect but with this new feature, we will use Azure bastion itself to initiate the connectivity. It means as long as Azure bastion can reach remote networks via Express route, Site-to-Site VPN, or Peering, we can initiate IP-based RDP/SSH connection to virtual machines. Azure Bastion now supports IP-Based connectivity to on-premises, Azure, and non-azure virtual machines. As long as Azure Bastion subnet can reach the remote network (via VNET peering, VPN), we can use the Azure Bastion service to connect. When we use Azure Bastion, virtual machines do not require public IP address to connect even if the VM is in a different VNET (same or different subscription). Azure Bastion is a PaaS service that provides seamless RDP/SSH connectivity to virtual machines via Azure portal. ![]()
