An apparatus and method shares predictive failure information between computer systems in a computer network. The shared predictive failure information allows a requester of a network resource to determine whether the resource will be available to perform the request based on its predictive failure information. According to a first embodiment, predictive failure information is written by each computer system on the network to a common storage that is accessible by one or more other computer systems on the network. When a computer system on the network needs a resource on another system, the requesting computer system can check the predictive failure status of the system that contains the needed resource by reading the predictive failure information in the common storage. If the predictive failure information indicates that the resource may perform the requested function, the requesting computer system issues the request to the resource. In a second embodiment, one or more network protocols for communicating between computer systems on the network are modified so that messages given in response to resource requests include the predictive failure status of the requested system. Thus, if a requester needs data from another computer system, a message returned from that system in response to the request preferably includes predictive failure status or information indicating whether or not the request can be granted. If the predictive failure status or information indicates that the request can be granted, the requester performs the operation on the requested computer system. In this manner, predictive failure information can be used in granting access to resources between computer systems on a network, which allows accesses to be prevented if the predictive failure information indicates that the resource is likely to fail before completing the request.

A method and system for enabling secure IPsec tunnels within NAT without compromising security. A local network is configured with a gateway machine connected to the Internet and having an IPsec ID for interfacing with the Internet and a local IP / interface address for interfacing with the local network. Client machines are connected to the gateway machine and communicate with the Internet via the gateway and network address translation (NAT) techniques. Each client machine is configured with a local IP / interface address. The client machines are also provided with an alias of the IPsec ID for the gateway machine. When an IPsec request is received by the gateway machine to establish a tunnel (secure communication) with one of the clients, the gateway machine forwards the packet to the particular client using NAT. The client machine receives the request and since it has an alias of the gateway's IPsec ID, the client machine will confirm that it has one of the IPsec IDs in the packet. The client machine sends the reply packet back to the gateway machine, which then forwards it to the requesting machine over the Internet. The requesting machine receives the packet and a confirmation that it has reached its intended recipient and opens the secure IKE tunnel with the particular client via the gateway machine. In this manner authentication of the IKE tunnel and establishment of a secure IPsec session is completed with a client machine that is accessible only via a gateway implementing NAT.
