Can you please explain how NAT gateway works?

Question

Hi Q&A,

I have doubt on NAT gateway.

If I create NAT gateway by taking public IP of my VM, can I able to access my VM with associated public IP address?

If it is not able to access, how can I access if i configure NAT to my VM?

Hi @Vishwa Teja Devarakonda,

I understand that you want to know about Nat Gateway.

• Azure Nat Gateway is used for Internet Bound Communication not for the access the VM and can't be associate to the VM.
• It provides outbound internet connectivity for virtual machines without requiring public IP addresses on each VM
• It can be attached to subnet in the vnet.

If I create NAT gateway by taking public IP of my VM, can I able to access my VM with associated public IP address?

No.

If it is not able to access, how can I access if i configure NAT to my VM?

To access the VM, please use the Public IP for inbound access. Nat Gateway only used for the Outbound access to the internet.
