powershell command for creating new Inbound NAT Pool of Existing Load Balancer

Question

I want to attach an existing Azure Load Balancer to Virtual Machine Scale Set, for this i need to create inbound nat pool so that i can take the resource ID of the inbound nat pool and pass it to the ARM Template of VMSS. thanks in advance.

Answer 1

According to my research, we can use the PowerShell command New-AzLoadBalancerInboundNatPoolConfig to create an inbound nat pool. For more details, please refer to https://learn.microsoft.com/en-us/powershell/module/az.network/New-AzLoadBalancerInboundNatPoolConfig?view=azps-2.8.0.

For example:

Connect-AzAccount

$slb = Get-AzLoadBalancer -Name "testload" -ResourceGroupName "testfun07"
$feIpConfig = Get-AzLoadBalancerFrontendIpConfig -Name "LoadBalancerFrontEnd" -Loadbalancer $slb

New-AzLoadBalancerInboundNatPoolConfig -Name "myInboundNatPool" -FrontendIpConfigurationId $feIpConfig.Id -Protocol TCP -FrontendPortRangeStart 1001 -FrontendPortRangeEnd 2000 -BackendPort 1001

Update

If we want to use PowerShell to create Inbound NAT Pool for an existing Load balancer, we need to do the following steps

1. Create a Inbound NAT Pool

$slb = Get-AzureRmLoadBalancer -Name "testload" -ResourceGroupName "testfun07"

$feIpConfig = Get-AzureRmLoadBalancerFrontendIpConfig -Name "LoadBalancerFrontEnd" -Loadbalancer $slb

Add-AzureRmLoadBalancerInboundNatPoolConfig -LoadBalancer $slb -Name "myInboundNatPool" -FrontendIpConfigurationId $feIpConfig.Id -Protocol TCP -FrontendPortRangeStart 1001 -FrontendPortRangeEnd 2000 -BackendPort 1001

2. Configure the ppol for the laad balancer

Set-AzureRmLoadBalancerInboundNatPoolConfig -LoadBalancer $slb -Name "myInboundNatPool" -FrontendIpConfigurationId $feIpConfig.Id -Protocol TCP -FrontendPortRangeStart 1001 -FrontendPortRangeEnd 2000 -BackendPort 1001

3. Update the load balancer

Set-AzureRmLoadBalancer -LoadBalancer $slb

For example

$name = "you account"
$password = "password"
$secpasswd = ConvertTo-SecureString $password -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential ($name, $secpasswd)
Connect-AzureRmAccount -Credential $mycreds 

$slb = Get-AzureRmLoadBalancer -Name "testload" -ResourceGroupName "testfun07"

$feIpConfig = Get-AzureRmLoadBalancerFrontendIpConfig -Name "LoadBalancerFrontEnd" -Loadbalancer $slb

Add-AzureRmLoadBalancerInboundNatPoolConfig -LoadBalancer $slb -Name "myInboundNatPool" -FrontendIpConfigurationId $feIpConfig.Id -Protocol TCP -FrontendPortRangeStart 1001 -FrontendPortRangeEnd 2000 -BackendPort 1001

Get-AzureRmLoadBalancer -Name "testload" -ResourceGroupName "testfun07" | Select-Object InboundNatPools | fl | Out-File -FilePath E:\mytest.txt -Append -Encoding utf8



Set-AzureRmLoadBalancerInboundNatPoolConfig -LoadBalancer $slb -Name "myInboundNatPool" -FrontendIpConfigurationId $feIpConfig.Id -Protocol TCP -FrontendPortRangeStart 1001 -FrontendPortRangeEnd 2000 -BackendPort 1001

Get-AzureRmLoadBalancer -Name "testload" -ResourceGroupName "testfun07" | Select-Object InboundNatPools | fl | Out-File -FilePath E:\mytest.txt -Append -Encoding utf8



Set-AzureRmLoadBalancer -LoadBalancer $slb

"3" | Out-File -FilePath E:\mytest.txt -Append -Encoding utf8

Get-AzureRmLoadBalancer -Name "testload" -ResourceGroupName "testfun07" | Select-Object InboundNatPools | fl | Out-File -FilePath E:\mytest.txt -Append -Encoding utf8
