Tutorial: Route network traffic with a route table

Статья
12.04.2025

Azure routes traffic between all subnets within a virtual network, by default. You can create your own routes to override Azure's default routing. Custom routes are helpful when, for example, you want to route traffic between subnets through a network virtual appliance (NVA).

In this tutorial, you learn how to:

Create a virtual network and subnets
Create an NVA that routes traffic
Deploy virtual machines (VMs) into different subnets
Create a route table
Create a route
Associate a route table to a subnet
Route traffic from one subnet to another through an NVA

Azure Cloud Shell

Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. You can use either Bash or PowerShell with Cloud Shell to work with Azure services. You can use the Cloud Shell preinstalled commands to run the code in this article, without having to install anything on your local environment.

To start Azure Cloud Shell:

Option	Example/Link
Select Try It in the upper-right corner of a code or command block. Selecting Try It doesn't automatically copy the code or command to Cloud Shell.
Go to https://shell.azure.com, or select the Launch Cloud Shell button to open Cloud Shell in your browser.
Select the Cloud Shell button on the menu bar at the upper right in the Azure portal.

To use Azure Cloud Shell:

Start Cloud Shell.
Select the Copy button on a code block (or command block) to copy the code or command.
Paste the code or command into the Cloud Shell session by selecting Ctrl+Shift+V on Windows and Linux, or by selecting Cmd+Shift+V on macOS.
Select Enter to run the code or command.

If you choose to install and use PowerShell locally, this article requires the Azure PowerShell module version 1.0.0 or later. Run Get-Module -ListAvailable Az to find the installed version. If you need to upgrade, see Install Azure PowerShell module. If you're running PowerShell locally, you also need to run Connect-AzAccount to create a connection with Azure.

Create subnets

A DMZ and Private subnet are needed for this tutorial. The DMZ subnet is where you deploy the NVA, and the Private subnet is where you deploy the virtual machines that you want to route traffic to. The subnet-1 is the subnet created in the previous steps. Use subnet-1 for the public virtual machine.

    Name = 'route-table-public'
    ResourceGroupName = 'test-rg'
    Location = 'eastus2'
}
$routeTablePublic = New-AzRouteTable @routeTableParams

Create a route by retrieving the route table object with Get-AzRouteTable, create a route with Add-AzRouteConfig, then write the route configuration to the route table with Set-AzRouteTable.

$routeTableParams = @{
    ResourceGroupName = "test-rg"
    Name = "route-table-public"
}

$routeConfigParams = @{
    Name = "to-private-subnet"
    AddressPrefix = "10.0.2.0/24"
    NextHopType = "VirtualAppliance"
    NextHopIpAddress = "10.0.3.4"
}

$routeTable = Get-AzRouteTable @routeTableParams
$routeTable | Add-AzRouteConfig @routeConfigParams | Set-AzRouteTable

Associate the route table with the subnet-1 subnet with Set-AzVirtualNetworkSubnetConfig. The following example associates the route-table-public route table with the subnet-1 subnet.

$vnetParams = @{
    Name = 'vnet-1'
    ResourceGroupName = 'test-rg'
}
$virtualNetwork = Get-AzVirtualNetwork @vnetParams

$subnetParams = @{
    VirtualNetwork = $virtualNetwork
    Name = 'subnet-1'
    AddressPrefix = '10.0.0.0/24'
    RouteTable = $routeTablePublic
}
Set-AzVirtualNetworkSubnetConfig @subnetParams | Set-AzVirtualNetwork

Create a route table with az network route-table create. The following example creates a route table named route-table-public.

# Create a route table
az network route-table create \
    --resource-group test-rg \
    --name route-table-public

Create a route in the route table with az network route-table route create.

az network route-table route create \
    --name to-private-subnet \
    --resource-group test-rg \
    --route-table-name route-table-public \
    --address-prefix 10.0.2.0/24 \
    --next-hop-type VirtualAppliance \
    --next-hop-ip-address 10.0.3.4

Associate the route-table-subnet-public route table to the subnet-1 subnet with az network vnet subnet update.

az network vnet subnet update \
    --vnet-name vnet-1 \
    --name subnet-1 \
    --resource-group test-rg \
    --route-table route-table-public

Test the routing of network traffic

Test routing of network traffic from vm-public to vm-private. Test routing of network traffic from vm-private to vm-public.

Test network traffic from vm-public to vm-private

In the search box at the top of the portal, enter Virtual machine. Select Virtual machines in the search results.
In Virtual machines, select vm-public.
Select Connect then Connect via Bastion in the Overview section.
Enter the username and password you entered when the virtual machine was created.
Select Connect.
In the prompt, enter the following command to trace the routing of network traffic from vm-public to vm-private:
```
tracepath vm-private
```
The response is similar to the following example:
```
azureuser@vm-public:~$ tracepath vm-private
 1?: [LOCALHOST]                      pmtu 1500
 1:  vm-nva.internal.cloudapp.net                          1.766ms 
 1:  vm-nva.internal.cloudapp.net                          1.259ms 
 2:  vm-private.internal.cloudapp.net                      2.202ms reached
 Resume: pmtu 1500 hops 2 back 1 
```
You can see that there are two hops in the above response for tracepath ICMP traffic from vm-public to vm-private. The first hop is vm-nva. The second hop is the destination vm-private.

Azure sent the traffic from subnet-1 through the NVA and not directly to subnet-private because you previously added the to-private-subnet route to route-table-public and associated it to subnet-1.
Close the Bastion session.

Test network traffic from vm-private to vm-public

In the search box at the top of the portal, enter Virtual machine. Select Virtual machines in the search results.
In Virtual machines, select vm-private.
Select Connect then Connect via Bastion in the Overview section.
Enter the username and password you entered when the virtual machine was created.
Select Connect.
In the prompt, enter the following command to trace the routing of network traffic from vm-private to vm-public:
```
tracepath vm-public
```
The response is similar to the following example:
```
azureuser@vm-private:~$ tracepath vm-public
 1?: [LOCALHOST]                      pmtu 1500
 1:  vm-public.internal.cloudapp.net                       2.584ms reached
 1:  vm-public.internal.cloudapp.net                       2.147ms reached
 Resume: pmtu 1500 hops 1 back 2 
```
You can see that there's one hop in the above response, which is the destination vm-public.

Azure sent the traffic directly from subnet-private to subnet-1. By default, Azure routes traffic directly between subnets.
Close the Bastion session.

When you finish using the resources that you created, you can delete the resource group and all its resources.

In the Azure portal, search for and select Resource groups.
On the Resource groups page, select the test-rg resource group.
On the test-rg page, select Delete resource group.
Enter test-rg in Enter resource group name to confirm deletion, and then select Delete.

When no longer needed, use Remove-AzResourcegroup to remove the resource group and all of the resources it contains.

$rgParams = @{
    Name = "test-rg"
}
Remove-AzResourceGroup @rgParams -Force

When no longer needed, use az group delete to remove the resource group and all of the resources it contains.

az group delete \
    --name test-rg \
    --yes \
