IP Security Architecture in Shared-IP Zones

IPsec can be used in the global zone. However, IPsec in a non-global zone cannot use IKE. Therefore, you must manage the IPsec keys and policy for the non-global zones by using the Internet Key Exchange (IKE) protocol in the global zone. Use the source address that corresponds to the non-global zone that you are configuring.
