Syntax

Set-AzureRmFirewall
   -AzureFirewall <PSAzureFirewall>
   [-AsJob]
   [-DefaultProfile <IAzureContextContainer>]
   [-WhatIf]
   [-Confirm]
   [<CommonParameters>]

Description

The Set-AzureRmFirewall cmdlet updates an Azure Firewall.

Examples

1: Update priority of a Firewall application rule collection

$azFw = Get-AzureRmFirewall -Name "AzureFirewall" -ResourceGroupName "rg"
$ruleCollection = $azFw.GetApplicationRuleCollectionByName("ruleCollectionName")
$ruleCollection.Priority = 101
Set-AzureRmFirewall -Firewall $azFw

This example updates the priority of an existing rule collection of an Azure Firewall. Assuming Azure Firewall "AzureFirewall" in resource group "rg" contains an application rule collection named "ruleCollectionName", the commands above will change the priority of that rule collection and update the Azure Firewall afterwards. Without the Set-AzureRmFirewall command, all operations performed on the local $azFw object are not reflected on the server.

2: Create a Azure Firewall and set an application rule collection later

$azFw = New-AzureRmFirewall -Name "AzureFirewall" -ResourceGroupName "rg" -VirtualNetworkName "vnet-name" -PublicIpName "pip-name"

$rule = New-AzureRmFirewallApplicationRule -Name R1 -Protocol "http:80","https:443" -TargetFqdn "*google.com", "*microsoft.com" -SourceAddress "10.0.0.0"
$RuleCollection = New-AzureRmFirewallApplicationRuleCollection -Name RC1 -Priority 100 -Rule $rule -ActionType "Allow"
$azFw.ApplicationRuleCollections = $RuleCollection

$azFw | Set-AzureRmFirewall

In this example, a Firewall is created first without any application rule collections. Afterwards a Application Rule and Application Rule Collection are created, then the Firewall object is modified in memory, without affecting the real configuration in cloud. For changes to be reflected in cloud, Set-AzureRmFirewall must be called.
