Configuring a site-to-site VPN for IPsec VPN sites

Use Colt® Private Cloud on VMware Cloud Foundation™ to configure a site‑to‑site VPN (virtual private network) for IPsec VPN sites. Use this VPN to connect Colt Private Cloud on VMware Cloud Foundation™ to your Colt® Edge Private Cloud service. After you configure this, you must configure your Colt Cloud to finish the connection. For more security, consider enabling distributed firewalls on your networks.

    1. Authentication Mode—Select one of the following options:

      • Pre‑Shared Key—Use a pre‑shared key for authentication. The configuration of NAT (network address translation) determines the pre‑shared key. If you configure NAT on the remote ID, enter the private IP address of the remote site. Otherwise, use the public IP address of the remote device.

      • Certificate—User certificates for authentication. The remote ID must match the certificate SAN (Subject Alternative Name). If the certificate SAN is not available, the remote ID must match the distinguished name of the certificate used to secure the remote endpoint.

    2. Pre‑Shared Key—If your authentication uses a pre‑shared key, type the pre‑shared key for the IPSec VPN tunnel.

    3. Server Certificate—If you are authenticating using a certification, click Select, then select the server certificate in the Use VMware Cloud Director Certificate section.

    4. CA Certificate—If you are authenticating using a certification, click Select, then select the CA (certificate authority) certificate in the Use VMware Cloud Director Certificate section.
