When I just look at your problem it seems to be easier to set up the tunnel
slightly different and pull with standard wget. If the URL looks like
and you set up the tunnel with
  ssh -L 7193:<host>:<port> <machine-where-you-called-wget-previously>
and then just
  wget http://localhost:7193/<rest>
the range requests would be sent by wget just fine to the initial server and
you could also safely use -c on further wget invocations (or with proper values
for -t / -T automatically).

Best regards
