Abstract
A technique for processing secure data packets that are directly and not directly addressed to a policy enforcement point (PEP). The present invention incorporates a dual internal path for the fast path processing of secure data packets at a PEP. A first path is used to process secure data packets addressed to the PEP. A second path is used to process secure data packets not addressed to the PEP. On the first path, secure data packets addressed to the PEP are transferred to the PEP for immediate processing. On the second path, a series of checks are performed to maximize the speed of processing the secure data packets. In addition, policies associated with the secure data packets are retrieved and destination address/mask combinations are used along with destination addresses in the secure data packets to determine if the packets are to be further processed or dropped.
