Description

The New-AzNetworkSecurityGroup cmdlet creates an Azure network security group.

Examples

Example 1: Create a new network security group

New-AzNetworkSecurityGroup -Name "nsg1" -ResourceGroupName "rg1"  -Location  "westus"

This command creates a new Azure network security group named "nsg1" in resource group "rg1" in location "westus".

Example 2: Create a detailed network security group

$rule1 = New-AzNetworkSecurityRuleConfig -Name rdp-rule -Description "Allow RDP" `
    -Access Allow -Protocol Tcp -Direction Inbound -Priority 100 -SourceAddressPrefix `
    Internet -SourcePortRange * -DestinationAddressPrefix * -DestinationPortRange 3389

$rule2 = New-AzNetworkSecurityRuleConfig -Name web-rule -Description "Allow HTTP" `
    -Access Allow -Protocol Tcp -Direction Inbound -Priority 101 -SourceAddressPrefix `
    Internet -SourcePortRange * -DestinationAddressPrefix * -DestinationPortRange 80

$nsg = New-AzNetworkSecurityGroup -ResourceGroupName TestRG -Location westus -Name `
    "NSG-FrontEnd" -SecurityRules $rule1,$rule2

Step:1 Create a security rule allowing access from the Internet to port 3389.
Step:2 Create a security rule allowing access from the Internet to port 80.
Step:3 Add the rules created above to a new NSG named NSG-FrontEnd.

Example 3: Create a new network security group with flush connection

New-AzNetworkSecurityGroup -Name "nsg1" -ResourceGroupName "rg1"  -Location  "westus" -FlushConnection

This command creates a new Azure network security group named "nsg1" in resource group "rg1" in location "westus" and enables flushing of connection.
