  Various aspects of forward physics have been studied by the ATLAS
collaboration using data from Run I at the LHC. In this text, main results of
three published analyses are summarized, based on data from proton-proton
collisions at $\sqrt{s} = 7$ or 8 TeV collected between 2010 and 2012. One
analysis deals with diffractive signature with at least two jets in the final
state, the other two study exclusive production of a pair of leptons or W
bosons.
