Creating a new firewall with PowerShell

Alternatively, we can deploy Azure Firewall using PowerShell. This method is especially useful when services are part of a large deployment or any deployment that needs to be automated.

How to do it...

There are several steps that need to be executed in order to create a new firewall with Azure PowerShell:

1. First, we define the parameters:

   $RG="Packt-Networking-Script"
   $Location="West Europe"
   $VNetName = "Packt-Script"
   $AzFwIpName = "AzFW-Public-IP"
   $AzFwname = "AzFw-Script"

2. Then, we need to create a separate subnet for Azure Firewall:

   $vnet = Get-AzVirtualNetwork -ResourceGroupName $RG '
   -Name $VnetName
   Add-AzVirtualNetworkSubnetConfig -Name AzureFirewallSubnet '
   -VirtualNetwork $vnet '
   -AddressPrefix 10.11.3.0/24
   Set-AzVirtualNetwork -VirtualNetwork $vnet 

3. Next, we need to create a public IP address for Azure Firewall:

   $AzFwIp = New-AzPublicIpAddress -Name ...
