ABSTRACT:
A system, method and computer program for routing a response packet in a session along a path similar to a request packet's outbound path that includes a firewall and a first router. The firewall receives the request packet and forwards the request packet to the first router. Upon receipt of the request packet, the firewall and first router broadcast session information to their respective sets of directly connected devices. A second router receives the response packet. After determining that the second router was not in the outbound path according to the second router's session table, the second router forwards the response packet to the device (i.e., the firewall or the first router) that is most upstream in the outbound path among the outbound path devices that are available and connected to the second router.
