12. Creating a Hub and Spoke Network with a DMZ and Allowing Access to Azure Arc and Other Microsoft URLs from the Azure Portal.
1. Create a Hub Virtual Network
- Go to the Azure Portal: Navigate to the Azure portal (
https://azure.microsoft.com/en-us/get-started/azure-portal - Create a Resource: Click on "Create a resource" in the top left corner.
- Search for Virtual Network: Search for "Virtual network" and select it.
- Choose Deployment Model: Select "Hub and spoke" as the deployment model.
- Configure Hub Settings:
- Name: Provide a unique name for your hub virtual network.
- Location: Choose a region where you want to deploy the hub.
- Address Space: Define the address space for the hub virtual network.
- Subnet Configuration: Create a subnet for the hub gateway.
- Create: Click "Create" to start the deployment.
2. Create Spoke Virtual Networks
- Repeat Step 1: Follow the same steps as above to create spoke virtual networks for different workloads.
- Configure Spoke Settings:
- Name: Provide a unique name for each spoke virtual network.
- Location: Choose the same region as the hub virtual network.
- Address Space: Define the address space for each spoke virtual network.
- Subnet Configuration: Create subnets for the application workload and peering connection to the hub.
3. Create Peering Connections
- Go to Virtual Network: Navigate to the hub virtual network.
- Peering: Click on "Peering" under the "Connectivity" section.
- Create Peering: Click on "Create peering."
- Configure Peering:
- Name: Provide a name for the peering connection.
- Remote virtual network: Select the spoke virtual network you want to peer with.
- Allow gateway traffic: Select this option to enable traffic between the hub and spoke virtual networks.
- Create: Click "Create" to establish the peering connection.
- Repeat for Other Spoke Networks: Repeat these steps for each spoke virtual network.
4. Create a DMZ Virtual Network
- Follow Step 1: Create a new virtual network for the DMZ.
- Configure DMZ Settings:
- Name: Provide a unique name for the DMZ virtual network.
- Location: Choose the same region as the hub and spoke virtual networks.
- Address Space: Define the address space for the DMZ virtual network.
- Subnet Configuration: Create subnets for the DMZ resources.
5. Create a Peering Connection Between Hub and DMZ
- Follow Step 3: Create a peering connection between the hub virtual network and the DMZ virtual network.
- Configure Peering:
- Allow gateway traffic: Select this option to enable traffic between the hub and DMZ virtual networks.
6. Configure Network Security Groups (NSGs)
- Go to Network Security Groups: Navigate to the NSG associated with the DMZ subnet.
- Inbound Rules: Create inbound rules to allow traffic from the hub virtual network to the DMZ subnet.
- Outbound Rules: Create outbound rules to allow traffic from the DMZ subnet to Azure Arc and other Microsoft URLs.
- Review and Apply: Review the rules and apply them to the NSG.
7. Configure Azure Firewall (Optional)
- Create Azure Firewall: If you want to use Azure Firewall, create a new Azure Firewall resource.
- Associate with DMZ: Associate the Azure Firewall with the DMZ virtual network.
- Configure Rules: Create rules to allow traffic to and from the DMZ subnet.
8. Test Connectivity
- Test Access: From a resource within the DMZ virtual network, attempt to access Azure Arc and other Microsoft URLs.
- Verify Connectivity: Ensure that the traffic is flowing correctly and that you can access the desired resources.
By following these steps, you can successfully create a hub and spoke network with a DMZ and allow access to Azure Arc and other Microsoft URLs from the Azure portal.
