Download Internet Gateway Vs Nat Gateway Background. Internet gateway is used to connect a vpc to the internet and nat gateway is used to connect the private subnet to the internet (which means what ever traffic is coming to private subnet instance which will forward to the nat gateway). Nat gateway is added to give instances in private subnet access to the internet.
Imagine you have resources that need to receive inbound traffic from the internet (for example, web servers). A nat gateway resource will use all ip addresses associated with the resource for outbound connections from all subnets configured with the same nat gateway resource. Update this route table so that 0.0.0.0/0 points to the id of the nat gateway that you created.
