AzureFirewallPolicyExportImport

This (quickly created repo) contains PowerShell scripts and Bicep templates to export Azure Firewall Rule Collection Policies into a CSV file that can be edited then reimported to quickly update the rules.

Using the scripts

1. Export the rules from the Azure Firewall Policy using the Export-AzFirewallPolicyRules.ps1 script. This will create a CSV file with the rules.
2. Edit the CSV file to make the changes you want.
3. Import the rules back into the Azure Firewall Policy using the Invoke-DeployFirewallPolicyRules.ps1 script. This will import the updated CSV file and deploy it to the Azure Firewall Policy.

Example

Connect-AzAccount

Export-AzureFirewallPolicyRules.ps1 -FirewallPolicyId "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/MyResourceGroup/providers/Microsoft.Network/azureFirewalls/MyFirewall/azureFirewallPolicies/MyFirewallPolicy"
# The CSV file by default will be saved under .\src\FirewallPolicies.csv, edit it then run the following part

Invoke-DeployFirewallPolicyRules.ps1 -SubscriptionId "00000000-0000-0000-0000-000000000000" -ResourceGroupName "MyResourceGroup" -FirewallPolicyName "MyFirewallPolicy"
