  Einstein-Podolsky-Rosen (EPR) steering is a quantum mechanical phenomenon
that allows one party to steer the state of a distant party by exploiting their
shared entanglement. It has potential applications in secure quantum
communication. In this paper, we present two swapping schemes of Gaussian EPR
steering, single-channel and dual-channel schemes, by the technique of
entanglement swapping. Two space-separated independent EPR steering states
without a direct interaction present EPR steering after deterministic swapping.
By comparing the EPR steering of the single-channel and dual-channel schemes,
we show that the transmission distance of the single-channel scheme is much
longer than that of the symmetric dual-channel scheme. Different from
entanglement swapping, one-way EPR steering is presented after swapping over
lossy channels. The most interesting thing is that the change of the EPR
steering direction is observed in the dual-channel scheme. We also show that
excess noise in a quantum channel will shorten the transmission distance of the
swapping, even leading to the sudden death of EPR steering. The presented
schemes provide a technical reference for remote quantum communications with
EPR steering.
