  In the evolution of late universe, the main source of matter are Dark energy
and Dark matter. They are indirectly detected only through their gravitational
manifestations. So the possibility of interaction with each other without
violating observational restrictions is not ruled out. With this motivation, we
investigate the dynamics of DGP braneworld where source of dark energy is a
scalar field and it interacts with matter source. Since observation favours
phantom case more, we have also studied the dynamics of interacting phantom
scalar field. In non interacting DGP braneworld there are no late time
accelerated scaling attractors and hence cannot alleviate Coincidence problem.
In this paper, we shall show that it is possible to get late time accelerated
scaling solutions. The phase space is studied by taking two categories of
potentials (Exponential and Non exponential functions). The stability of
critical points are examined by taking two specific interactions. The first
interaction gives late time accelerated scaling solution for phantom field only
under exponential potential, while for second interaction we do not get any
scaling solution. Furthermore, we have shown that this scaling solution is also
classically stable.
