  We analyze the background cosmology for an extension of the DGP gravity with
Gauss-Bonnet term in the bulk and $f(R)$ gravity on the brane. We investigate
implications of this setup on the late-time cosmic history. Within a dynamical
system approach, we study cosmological dynamics of this setup focusing on the
role played by curvature effects. Finally we constraint the parameters of the
model by confrontation with recent observational data.
