I don't use scp from outside a firewall... but scp passes through a single
ssh tunnel, so if ssh works, the networking portion of scp should work,
and Bering should have absolutely nothing to do with it.
I would review the names for your hosts... each endpoint should be able to
identify the other. To eliminate name resolution from the picture for
troubleshooting, use ip addresses in your file-specifications.
Also, confirm that scp is installed and working on each end. Try ssh'ing
to the other end, and scp'ing from there. Also try the -v option.
