# AWS Networking: VPN

<Info>This connection option is only available for dedicated Astro clusters.</Info>

Use this connectivity type to access on-premises resources or resources in other cloud providers.

## Prerequisites

* Configured gateway device or application with Public IP address. You need 2 addresses for an HA setup.

Contact your internal network team or engineer and ask for the following information:

* Public IP addresses for the tunnels configuration.
* IKE pre-shared key, if your team wants to use a particular key.
* Preferable settings for phase 1 and phase 2 (BGP only) IKE negotiations.
* ASN for BGP or IP prefixes for static configuration.
* (Optional) A size /30 IPv4 CIDR block from the 169.254.0.0/16 range for the inside tunnel IPv4 addresses.
