# Connections in AWS Global Networks for Transit Gateways
<a name="device-connections"></a>

Create a connection between two devices in your global network using AWS Network Manager. The connection can be between a physical or virtual appliance and a third-party appliance in a VPC, or between physical appliances in an on-premises network. To create a connection the device must first be added to your global network. For the steps to add a device, see [Add a device using AWS Network Manager](nm-devices-add.md). You can also use an optional link to create the connection. For the steps to create a link, see [Add a link using AWS Network Manager](nm-site-link-add.md).

A connection is created for a specific global network and cannot be shared with other global networks.
