  The light cone gauge is used frequently in string theory as well as gauge
theories and gravitation. Loop integrals however have to be infrared regulated
to remove spurious poles. The most popular and consistent of these infrared
regulators is the Mandelstam-Leibbrandt(ML) prescription. The calculations with
ML are rather cumbersome, though. In this work we show that the ML can be
replaced by a symmetry of the regulator. This symmetry simplify the
calculations, reducing them to conventional dimensional regularization
integrals.
