1. A system comprising:
- a gateway device coupled to a LAN and configured to provide a plurality of Virtual Private Network (VPN) tunnels between the Local Area Network (LAN) and a public network;
at least one slave device coupled to the gateway device configured to perform IPsec processing of a first portion of the plurality of virtual private network tunnels and return the first portion of the plurality of virtual private network tunnels back to the gateway device for firewall processing; and
a plurality of devices coupled to the LAN and configured to communicate using at least one of the plurality of VPN tunnels.

Abstract
One embodiment of the application provides a method and system for receiving at a gateway device a plurality of virtual private network tunnels to be routed to a Local Area Network (LAN), routing a first portion of the plurality of virtual private network tunnels to at least one slave device coupled to the gateway device, performing IPsec processing of the first portion of the plurality of virtual private network tunnels using at least one slave device, forwarding the first portion of the plurality of virtual private network tunnels after IPsec processing to at the gateway device and routing the plurality of virtual private network tunnels to the LAN.
