 -R [bind_address:]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 connection is forwarded over the
         secure channel, and a connection is made to host port
         hostport from the local machine.

         Port forwardings 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 by enclosing the address in
         square braces or using an alternative syntax:
         [bind_address/]host/port/hostport.

         By default, the listening socket on the server will be
         bound to the loopback interface only.  This may be
         overridden by specifying a bind_address.  An empty
         bind_address, or the address ‘*’, indicates that the
         remote socket should listen on all interfaces.
         Specifying a remote bind_address will only succeed if the
         server's GatewayPorts option is enabled (see
         sshd_config(5)).

         If the port argument is ‘0’, the listen port will be
         dynamically allocated on the server and reported to the
         client at run time.
