There are several steps to configuring a star site-to-site VPN.
First, the central hub gateway must be configured with a tunnel connection to every remote gateway. Then, every remote gateway must be configured with a connection back to the central hub.

Procedure

  1. Create local and remote address objects that you will need during the VPN configuration.
    For information about what address objects are needed, you can review the example: Example: Star Site-to-Site VPN
  2. Choose which IPsec policy to use when configuring the IPsec VPN connections.
    IPsec policies are selected when configuring an IPsec VPN connection. You can use the Default IPsec policy, use another existing policy, or you can add a new IPsec policy.
  3. On the central hub gateway, set up a connection to each spoke device.
  4. On each spoke gateway, set up a connection to the hub device.
  5. Optional: Configure advanced options for site-to-site VPN settings including dead peer detections and enabling or disabling IKE debugging.
