Migrate your gateway to the new IP, and update the existing tunnel with the AWS IP and the new preshared key. Tunnel should go up automagically, and now all that remains is to update the subnet route tables to the correct VPN connection.

A virtual private gateway is a logical, fully redundant distributed edge routing function that sits at the edge of your VPC. As it is capable of terminating VPN connections from your on-prem or customer environments, the VPG is the VPN concentrator on the Amazon side of the Site-to-Site VPN connection. In fact for site to site vpn (h/w or s/w) IGW is not required. We have to have virtual private gateway . Typically VPN will use Pvt IP address and not the Public IP. The document states it very clearly. Q. How does an AWS Site-to-Site VPN connection work with Amazon VPC? An AWS Site-to-Site VPN connection connects your VPC to your datacenter. availability_zone - (Optional) The Availability Zone for the virtual private gateway. tags - (Optional) A map of tags to assign to the resource. amazon_side_asn - (Optional) The Autonomous System Number (ASN) for the Amazon side of the gateway.

If you are running a Transit VPC, perhaps using Cisco CSR, you may be wondering if there are any advantages to re-architecting to use the Transit Gateway. Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources into a virtual network that you’ve defined. A subnet is a range of IP addresses within the VPC. Subnets can be either public with a gateway to the internet or private. Mar 23, 2020 · Virtual Private Cloud: Logically isolated private network on AWS. Subnet: Logical division of VPC to create multiple sub networks. Internet Gateway: Component responsible to establish a connection with the Internet

This Internet gateway is a managed service, controlled, configured, and maintained by AWS. It scales horizontally automatically, and is classified as a highly valuable component of your VPC infrastructure. Once your Internet gateway is attached to your VPC, you have a gateway to the Internet.

The Direct Connect Gateway is connected to multiple AWS VPCs in different AWS regions via Virtual private Gateways. The Direct Connect Gateway is in turn connected to the Direct Connect via a virtual private interface. This allows multiple VPCs to be connected to the customer network via one virtual private interface. If an Internet gateway has not been configured, or if the instance is in a subnet configured to route through the virtual private gateway, the traffic traverses the VPN connection, egresses from your datacenter, and then re-enters the public AWS network.

The IKE security association is established first between the virtual private gateway and the customer gateway device using a pre-shared key or a private certificate that uses AWS Certificate Manager Private Certificate Authority as the authenticator.
