Abstract
A system and method for providing multiple virtual private networks (VPNs) from a computer system. Configuration information is maintained for connections, or tunnels, established between a local computer system and a number of remote computer systems. The configuration information includes information about the endpoints, or local-remote computer pairs, policies used to determine preferred access methods for connecting a given pair of computers, pre-shared keys, and digital certificates for providing keys to encrypt and decipher data. A local-remote pair is selected from an endpoints table. A policy corresponding to the selected local-remote pair is selected determining the access method(s) to be attempted in securely connecting the two computer systems. If an access method uses a digital certificate, the corresponding information is retrieved from a digital certificate table. The decision whether to check the digital certification has been revoked is stored in the endpoints table.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
