A "Gweep" is a combination GUAPPLE and iSweep.  The base unit is identical to a GUAPPLE and it runs a virtualized copy of an iSweep appliance, eliminating the need for two physical units.  (Note: on the network, the Gweep is still two logical units and requires two unique IP addresses - one for the GUAPPLE half, one for the iSweep half.)  The network requirements for the Gweep are identical to that of the GUAPPLE and iSweep.  Please review the articles below and ensure that the requirements of both are met:
