We study theoretically the transport through a single impurity in a one-channel Luttinger liquid coupled to a dissipative (Ohmic) bath. For nonzero dissipation, the single impurity is always a relevant perturbation which suppresses transport strongly. At zero temperature, the current voltage relation of the link is I\ensuremath∼exp(\ensuremath-E0/eV), where E0\ensuremath∼\ensuremathη/\ensuremathκ and \ensuremathκ denotes the compressibility. At nonzero temperature T, the linear conductance is proportional to exp(\ensuremath-√CE0/kBT). The decay of Friedel oscillation saturates for a distance larger than L_\ensuremathη\ensuremath∼1/\ensuremathη from the impurity.
