Acquia Cloud Shield¶

Network information you provide to Acquia¶

For Acquia to configure Acquia Cloud Shield with VPN, you must provide Acquia with the following information:

• Contact information (such as name, phone, and email) for the members of your internal network team.

• VPN device details:

  • VPN device type (vendor and model)
  • The Gateway IP address of the customer VPN device

  Confirm your VPN device meets the requirements.

• Network details, including the following:

  • A network diagram, showing which systems Acquia Cloud Shield will connect to:

  • Maintenance plan or schedule for your network services and hardware

  • CIDR IP blocks

    Note

    Acquia Cloud Shield requires a private, non-routable /16 or /20 private address space conforming with RFC 1597. Acquia Cloud Shield can use private, non-routable /16 or /20 CIDR blocks from the 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16 ranges. Blocks of this size provide resources for Acquia-controlled servers (such as Elastic Load Balancers) and other elastic scaling needs, and also provide expansion space for your application’s future needs.

  • Subnet allocations

  • A list of networks that need traffic statically routed to them

• (Optional) A name for the Acquia VPN. If you have multiple VPNs, providing a name to Acquia may be useful for later communication.

Contact your Acquia Account Manager for more information.

VPN device requirements¶

To connect to Acquia Cloud Shield with VPN, your network must use a VPN (a secure Internet gateway) using IPsec. Your VPN device must be capable of each of the following:

• Establish IKEv1 Security Associations using pre-shared keys
• Establish IPsec Security Associations in Tunnel mode
• Use the AES 128-bit encryption function
• Use the SHA-1 hashing function
• Use Diffie-Hellman Perfect Forward Secrecy in “Group 2” mode
• Perform packet fragmentation before encryption

The following gateway devices are compatible with Acquia Cloud Shield with VPN; other devices may work, but Acquia does not support them:

• Cisco ASA 5500 Series version 8.2 or greater software
• Cisco ISR running Cisco IOS 12.4 or greater software
• Dell SonicWALL Next Generation Firewalls (TZ, NSA, SuperMassive Series) running SonicOS5.8 or greater
• Juniper J-Series Service Router running JunOS 9.5 or greater software
• Juniper SRX-Series Services Gateway running JunOS 9.5 or greater software
• Juniper SSG running ScreenOS 6.1, or 6.2 or greater software
• Juniper ISG running ScreenOS 6.1, or 6.2 or greater software
• Microsoft Windows Server 2008 R2 or greater software
• Yamaha RTX1200 router

You must properly configure your network’s gateway to connect to Acquia Cloud Shield with VPN. After provisioning your dedicated section, Acquia will provide you with the configuration and VPN details containing the Pre-Shared Key (PSK) information you need to properly configure your VPN. The information will be stored in a secure location you will access using SSH.

Acquia Cloud Shield uses Dead Peer Detection (DPD), exchanging UDP packets between VPN peers to ensure both ends are available. If no traffic crosses the VPN tunnel in ten seconds, Acquia Cloud Shield sends a request. Three successive requests without a response will cause Acquia Cloud Shield to close the VPN tunnel.
