We consider the standard vector and chiral gauged WZNW models gauged by their
maximal null subgroups and show that they can be mapped to each other by a
special transformation. We give an explicit expression for the map in the case
of the classical Lie groups AN, BN, CN, DN, and note its connection with
the duality map for the Riemannian globally symmetric spaces.
