The syntax is "ssh -R port:host:hostport user at hostname"
which will forward "port" listening on "hostname" to
"host:hostport" via your local ssh-running machine (so
'localhost' means the machine you're currently running on,
and the first two make no sense). What are you trying to
forward to/from?

Running with -a should make the Dropbear server listen on
any interface. If you run netstat -antp|grep LISTEN (or
similar for your OS) what port does it show it listening on?
