ABSTRACT:
A system, method and computer program for routing a response packet along a path similar to a request packet's outbound path that includes a firewall, a first router, a first device and a second device. 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. Based on a determination that the second device is unavailable to receive the response packet, a second router receives the response packet. After determining that the second router was not in the outbound path, the second router forwards the response packet to the firewall if the firewall is available or to the first router if the first firewall is unavailable and the first router is available.
