maybe this may help (from the ssh manpage):

 -R port:host:hostport
  Specifies that the given port on the remote (server) host is to
  be forwarded to the given host and port on the local side.  This
  works by allocating a socket to listen to port on the remote
  side, and whenever a connection is made to this port, the connec-
  tion is forwarded over the secure channel, and a connection is
  made to host port hostport from the local machine.  Port forward-
  ings can also be specified in the configuration file.  Privileged
  ports can be forwarded only when logging in as root on the remote
  machine.  IPv6 addresses can be specified with an alternative
  syntax: port/host/hostport.

so executing "ssh -R 1021:server:22" with increasing server port number
(1021) should do it for you?
