Connecting to Azure VNet + Azure NAT

Question

Hi, I am relatively new to Azure and I have the following use-case.

I have an AKS cluster and a VM running in an Azure Virtual Network. I wish that all outbound traffic from Azure Virtual Network use a static IPv4 address. I think I can accomplish this with an Azure NAT Gateway. I need to access certain other applications running within another Cloud Environment. However these can only be accessed via IPv4 whitelisting. Thus, I need to have my static IPv4 address from my NAT whitelisted to access these from Azure. However, I both want to access these external applications and their APIs via my AKS cluster and a VM or VPN running in my Azure Virtual Network. Such that I can pivot via the Azure Virtual Network and then access the applications (through HTTPS) via the whitelisted IP from my NAT gateway. AKS cluster application uses the external applications API's, while I want to access the external applications via a browser, either via VPN or a VM.

How would I best setup my infrastructure on Azure for this setup? Thank you.

Hi @SA0015 , I understand that you want to use a fixed IPv4 address for your outbound traffic from both AKS and Azure VMs.

You can use NAT Gateway. You need to create NAT Gateway before creating your AKS cluster. Then setup your AKS cluster to use Outbound Type = userAssignedNatGateway.

For more information, see Create an AKS cluster with a user-assigned NAT gateway.
