Internetwork traffic privacy

To set up a private connection between your Amazon VPC and your corporate network, you can choose to set up either an IPsec VPN connection over the internet or a private physical connection using Direct Connect connection. Direct Connect enables you to establish a private virtual interface from your on-premises network directly to your Amazon VPC, providing you with a private, high-bandwidth network connection between your network and your VPC. With multiple virtual interfaces, you can establish private connectivity to multiple VPCs while maintaining network isolation. For more information, see [What is AWS Site-to-Site VPN?](https://docs.aws.amazon.com/vpn/latest/s2svpn/VPC_VPN.html) and [What is Direct Connect?](https://docs.aws.amazon.com/directconnect/latest/UserGuide/Welcome.html)

**To route traffic directly between MediaConnect and your corporate network via a virtual private cloud (VPC)**

1. Set up a private connection between your Amazon VPC and your corporate network. You can choose between an IPsec VPN connection over the internet or a private physical connection using Direct Connect connection.

1. [Create a flow that uses a VPC *source*](flows-create-vpc-source.md). During this process, you add a VPC *interface* to your flow to establish the initial connection between your VPC and your flow. You also specify that same VPC interface as the source for the new flow.
**Note**  
If your flow already exists, you can update the flow to [add a VPC interface](vpc-interface-add.md) and then [add another source that uses that VPC interface](source-adding-vpc.md).
