NSG

Azure Network Security Group

Copy NSG rules from existing NSG to create new NSG using Powershell:

# Connect and set source subscription
Connect-AzAccount
Set-AzContext -SubscriptionId "source-subscription-id"

# Get source NSG
$sourceNSG = Get-AzNetworkSecurityGroup -ResourceGroupName "source-rg" -Name "source-nsg-name"

# Switch to target subscription
Set-AzContext -SubscriptionId "target-subscription-id"

# Create new NSG with same rules
$newNSG = New-AzNetworkSecurityGroup -ResourceGroupName "target-rg" -Name "new-nsg-name" -Location "target-location" -SecurityRules $sourceNSG.SecurityRules
