Abstract
A packet-forwarding device for providing policy-based services has at least a first interface, a second interface, and a packet forwarder for forwarding external packets between the first and second interfaces. The packet-forwarding device also runs internal applications that may be remotely accessed. The first and second interfaces transmit and receive internal and external packets, the internal packets being those packets generated or received by the internal applications during remote access, and the external packets being those packets destined for devices other than the packet-forwarding device. The packet forwarder forwards external packets between the first and second interfaces. An internal interface forwards internal packets between the internal applications and the first and second interfaces, and a policy engine logically connected to the internal interface applies a policy to the internal packets.
