Abstract: A distributed firewall of a gateway device includes at least one IO module for performing IO functionality of the distributed firewall, at least one security processing module for performing security functionality of the distributed firewall and a firewall controller for managing the IO module and the security processing module. Each of the at least one IO and security processing modules is executed within a virtual machine. In response to a packet received from an ingress interface, the at least one IO module is to identify a security processing module corresponding to a connections session associated with the packet, to transmit the packet to the identified security processing module to perform a security process on the packet, and in response to a signal received from the identified security processing module indicating that the security process has been completed, to transmit the packet to the egress interface.
Abstract: A method and apparatus is disclosed herein for migrating session information between security gateways are disclosed. In one embodiment, receiving, at a first security gateway, session information associated with a session corresponding to a network connection, the session information having been transferred from a second security gateway, the first and second security gateway being separate physical devices; and thereafter performing security processing for the session at the first security gateway.
