Description

The New-AzFirewall cmdlet creates an Azure Firewall.

Examples

Example 1: Create a Firewall attached to a virtual network

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$pip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "publicIpName"
New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -PublicIpAddress $pip

This example creates a Firewall attached to virtual network "vnet" in the same resource group as the firewall. Since no rules were specified, the firewall will block all traffic (default behavior). Threat Intel will also run in default mode - Alert - which means malicious traffic will be logged, but not denied.

Example 2: Create a Firewall which allows all HTTPS traffic

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$pip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "publicIpName"

$rule = New-AzFirewallApplicationRule -Name R1 -Protocol "https:443" -TargetFqdn "*" 
$ruleCollection = New-AzFirewallApplicationRuleCollection -Name RC1 -Priority 100 -Rule $rule -ActionType "Allow"
New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -PublicIpAddress $pip -ApplicationRuleCollection $ruleCollection

This example creates a Firewall which allows all HTTPS traffic on port 443. Threat Intel will run in default mode - Alert - which means malicious traffic will be logged, but not denied.

Example 3: DNAT - redirect traffic destined to 10.1.2.3:80 to 10.2.3.4:8080

$rule = New-AzFirewallNatRule -Name "natRule" -Protocol "TCP" -SourceAddress "*" -DestinationAddress "10.1.2.3" -DestinationPort "80" -TranslatedAddress "10.2.3.4" -TranslatedPort "8080"
$ruleCollection = New-AzFirewallNatRuleCollection -Name "NatRuleCollection" -Priority 1000 -Rule $rule
New-AzFirewall -Name "azFw" -ResourceGroupName "rg" -Location centralus -NatRuleCollection $ruleCollection -ThreatIntelMode Off

This example created a Firewall which translated the destination IP and port of all packets destined to 10.1.2.3:80 to 10.2.3.4:8080 Threat Intel is turned off in this example.

Example 4: Create a Firewall with no rules and with Threat Intel in Alert mode

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$pip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "publicIpName"
New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -PublicIpAddress $pip -ThreatIntelMode Alert

This example creates a Firewall which blocks all traffic (default behavior) and has Threat Intel running in Alert mode. This means alerting logs are emitted for malicious traffic before applying the other rules (in this case just the default rule - Deny All)

Example 5: Create a Firewall which allows all HTTP traffic on port 8080, but blocks malicious domains identified by Threat Intel

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$pip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "publicIpName"

$rule = New-AzFirewallApplicationRule -Name R1 -Protocol "http:8080" -TargetFqdn "*" 
$ruleCollection = New-AzFirewallApplicationRuleCollection -Name RC1 -Priority 100 -Rule $rule -ActionType "Allow"
New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -PublicIpAddress $pip -ApplicationRuleCollection $ruleCollection -ThreatIntelMode Deny

This example creates a Firewall which allows all HTTP traffic on port 8080 unless it is considered malicious by Threat Intel. When running in Deny mode, unlike Alert, traffic considered malicious by Threat Intel is not just logged, but also blocked.

Example 6: Create a Firewall with no rules and with availability zones

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$pip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "publicIpName"
New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetworkName $vnet.Name -PublicIpName $pip.Name -Zone 1,2,3

This example creates a Firewall with all available availability zones.

Example 7: Create a Firewall with two or more Public IP Addresses

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -Name "vnet" -ResourceGroupName $rgName
$pip1 = New-AzPublicIpAddress -Name "AzFwPublicIp1" -ResourceGroupName "rg" -Sku "Basic" -Tier "Regional" -Location "centralus" -AllocationMethod Static
$pip2 = New-AzPublicIpAddress -Name "AzFwPublicIp2" -ResourceGroupName "rg" -Sku "Basic" -Tier "Regional" -Location "centralus" -AllocationMethod Static
New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -PublicIpAddress @($pip1, $pip2)

This example creates a Firewall attached to virtual network "vnet" with two public IP addresses.

Example 8: Create a Firewall which allows MSSQL traffic to specific SQL database

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$pip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "publicIpName"

$rule = New-AzFirewallApplicationRule -Name R1 -Protocol "mssql:1433" -TargetFqdn "sql1.database.windows.net"
$ruleCollection = New-AzFirewallApplicationRuleCollection -Name RC1 -Priority 100 -Rule $rule -ActionType "Allow"
New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -PublicIpAddress $pip -ApplicationRuleCollection $ruleCollection -ThreatIntelMode Deny

This example creates a Firewall which allows MSSQL traffic on standard port 1433 to SQL database sql1.database.windows.net.

Example 9: Create a Firewall attached to a virtual hub

$rgName = "resourceGroupName"
$fp = Get-AzFirewallPolicy -ResourceGroupName $rgName -Name "fp"
$fpId = $fp.Id
$vHub = Get-AzVirtualHub -Name "hub"
$vHubId = $vHub.Id

New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -SkuName AZFW_Hub -VirtualHubId $vHubId -FirewallPolicyId -$fpId

This example creates a Firewall attached to virtual hub "vHub". A firewall policy $fp will be attached to the firewall. This firewall allows/denies the traffic based on the rules mentioned in the firewall policy $fp. The virtual hub and the firewall should be in the same regions.

Example 10: Create a Firewall with threat intelligence allowlist setup

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$pip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "publicIpName"

$tiWhitelist = New-AzFirewallThreatIntelWhitelist -FQDN @("www.microsoft.com") -IpAddress @("8.8.8.8")
New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -PublicIpAddress $pip -ThreatIntelWhitelist $tiWhitelist

This example creates a Firewall that allowlists "www.microsoft.com" and "8.8.8.8" from threat intelligence

Example 11: Create a Firewall with customized private range setup

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$pip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "publicIpName"

New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -PublicIpAddress $pip -PrivateRange @("99.99.99.0/24", "66.66.0.0/16")

This example creates a Firewall that treats "99.99.99.0/24" and "66.66.0.0/16" as private ip ranges and won't snat traffic to those addresses

Example 12: Create a Firewall with a management subnet and Public IP address

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$pip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "publicIpName"
$mgmtPip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "managementPublicIpName"

New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -PublicIpAddress $pip -ManagementPublicIpAddress $mgmtPip

This example creates a Firewall attached to virtual network "vnet" in the same resource group as the firewall. Since no rules were specified, the firewall will block all traffic (default behavior). Threat Intel will also run in default mode - Alert - which means malicious traffic will be logged, but not denied.

To support "forced tunneling" scenarios, this firewall will use the subnet "AzureFirewallManagementSubnet" and the management public IP address for its management traffic

Example 13: Create a Firewall with Firewall Policy attached to a virtual network

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$pip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "publicIpName"
$fp = Get-AzFirewallPolicy -ResourceGroupName $rgName -Name "fp"
New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -PublicIpAddress $pip -FirewallPolicyId $fp

This example creates a Firewall attached to virtual network "vnet" in the same resource group as the firewall. The rules and threat intelligence that will be applied to the firewall will be taken from the firewall policy

Example 14: Create a Firewall with DNS Proxy and DNS Servers

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$pip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "publicIpName"
New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -PublicIpAddress $pip -DnsServer @("10.10.10.1", "20.20.20.2")

This example creates a Firewall attached to virtual network "vnet" in the same resource group as the firewall. DNS Proxy is enabled for this firewall and 2 DNS Servers are provided. Also Require DNS Proxy for Network rules is set so if there are any Network rules with FQDNs then DNS proxy will be used for them too.

Example 15: Create a Firewall with multiple IPs. The Firewall can be associated with the Virtual Hub

$rgName = "resourceGroupName"
$vHub = Get-AzVirtualHub -Name "hub"
$vHubId = $vHub.Id
$fwpips = New-AzFirewallHubPublicIpAddress -Count 2
$hubIpAddresses = New-AzFirewallHubIpAddress -PublicIP $fwpips
$fw=New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location westus -SkuName AZFW_Hub -HubIPAddress $hubIpAddresses -VirtualHubId $vHubId

This example creates a Firewall attached to virtual hub "hub" in the same resource group as the firewall. The Firewall will be assigned 2 public IPs that are created implicitly.

Example 16: Create a Firewall with Allow Active FTP.

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$pip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "publicIpName"
New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -PublicIpAddress $pip -AllowActiveFTP

This example creates a Firewall with allow active FTP flag.

Example 17: Create a Firewall with a management subnet and no data Public IP address

$rgName = "resourceGroupName"
$vnet = Get-AzVirtualNetwork -ResourceGroupName $rgName -Name "vnet"
$mgmtPip = Get-AzPublicIpAddress -ResourceGroupName $rgName -Name "managementPublicIpName"

New-AzFirewall -Name "azFw" -ResourceGroupName $rgName -Location centralus -VirtualNetwork $vnet -ManagementPublicIpAddress $mgmtPip

This example creates a "forced tunneling" Firewall that uses the subnet "AzureFirewallManagementSubnet" and the management public IP address for its management traffic. In this scenario, users do not have to specify a data Public IP if they are only using firewall for private traffic only.
