![]() New-AzResourceGroup -Name vm-networks -Location $Location These virtual networks can be in separate regions, allowing you to create a global interconnected network through Azure. Peering enables resources in each virtual network to communicate with each other. Virtual Network Peering: You can link virtual networks together using virtual network peering. A network virtual appliance carries out a particular network function, such as running a firewall or performing WAN optimization. Network virtual appliances: A network virtual appliance is a specialized VM that can be compared to a hardened network appliance.You can define these rules to allow or block traffic, based on factors such as source and destination IP address, port, and protocol. Network security groups: A network security group is an Azure resource that can contain multiple inbound and outbound security rules.Border Gateway Protocol: Border Gateway Protocol (BGP) works with Azure VPN gateways or ExpressRoute to propagate on-premises BGP routes to Azure virtual networks.You can create custom route tables that control how packets are routed between subnets. Route tables: A route table allows you to define rules as to how traffic should be directed.However, you can control routing and override those settings as follows: Azure ExpressRoute provides dedicated private connectivity to Azure that does not travel over the Internet.īy default, Azure will route traffic between subnets on any connected virtual networks, on-premises networks, and the Internet. Azure Express Route: For environments where you need greater bandwidth and even higher levels of security, Azure ExpressRoute is the best approach.This is done via Settings –> Configuration, and using the slider to change the number of instances from 2 to 50.AZ-104: Configure and manage virtual networks for Azure administrators – Learn | Microsoft DocsĮxplore Azure virtual networking – Learn | Microsoft Docs Once Azure Bastion is deployed, it is possible to scale the Standard SKU instance count up and down as required to support additional sessions. Note: You may need to accept popups when the console opens in another tab/window.ġ2. You will be connected to the VM console via your internet browser. Enter the username and password for the VM and click Connect.ġ1. To connect to a Virtual Machine via the new Bastion, navigate to the VM created earlier within the same Virtual Network, select Connect and Bastion from the sub menu.ġ0. Once complete you will see the Provisioning State “Succeeded” as below.ĩ. The Bastion will take a few minutes to deploy. Create a Bastion with the following settings:Ĩ. Search for “Bastion” and click Create Bastion.Ħ. Create a Virtual Machine and connect it to the subnet “snet-uks-t-mgmt-vms”.ĥ. Note: Azure Bastion requires its own subnet which must be named “AzureBastionSubnet” and this subnet should be at least a /27 in size.Ĥ. AzureBastionSubnet with an address range of 10.20.0.64/27.snet-uks-t-mgmt-vms with an address range of 10.20.0.0/26.Enter an Address Space for the Virtual Network e.g. 1 Bastion Standard connected to AzureBastionSubnetĢ.1 Windows VM connected to snet-uks-t-mgmt-vms.1 vNet with 2 Subnets (AzureBastionSubnet and snet-uks-t-mgmt-vms).Standard allows a configurable number of Bastion hosts between 2 and 50 enabling more sessions if required.īelow is a diagram of what we are going to create:.You can connect to any VM within the same vNet as Azure Bastion and any VM within any vNet peered directly with the vNet Bastion is deployed within, however it cannot traverse multiple vNet peerings. Provision the service directly in your local or peered virtual network to get support for all the VMs within it.”Īzure Bastion requires its own subnet which must be named “AzureBastionSubnet” and this subnet should be at least a /27 in size. “Azure Bastion is a fully managed service that provides more secure and seamless Remote Desktop Protocol (RDP) and Secure Shell Protocol (SSH) access to virtual machines (VMs) without any exposure through public IP addresses. It is simple to deploy a bastion host and there aren’t any additional extensions to install on the VM or within your browser for this to work. Azure Bastion also ensures anyone connecting is already authenticated via the Azure portal, before being prompted for server login credentials. This removes the risk of having a jump box exposed to the internet which is insecure. Azure Bastion is a PaaS service which allows you to securely connect to Virtual Machines using the Azure Portal using HTTPS without having to expose RDP or SSH to the internet via a public IP.
