Abstract
A gateway is provided which routes a packet sent from a user to a connected network utilizing a per-user routing table. This is accomplished by extracting a source address from the packet; finding a per-user routing table corresponding to the source address, the per-user routing table containing entries corresponding to one or more currently accessible networks for the user and the range of network addresses corresponding to the currently accessible networks; extracting a destination address from the packet; seeking an entry in the matching per-user routing table with a range of network addresses containing the destination address; routing the packet to a matching network if the destination address is contained within one of the ranges of network addresses for the currently accessible networks; and routing the packet to a default network if the destination address is not contained within one of the ranges of network addresses for the currently accessible networks. This allows different users to have access to a different set of networks and allows a user to select the network he wishes to access. The gateway may also guarantee that packet are routed through a particular destination ISP or network by looking up the destination ISP or network in a table, each entry in the table having a router network address corresponding to each network currently accessible; establishing a tunneling session to the matching router network address; and forwarding the packet to the router network address through the tunneling session.

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.
