I was playing around with `ssh -R` last night, and found                      
                                                    
that (even with -g, if that switch applies to this) ssh                       
                                                    
would only listen on the loop-back (127.0.0.1) address.

From sshd_config(5):


     GatewayPorts
             Specifies whether remote hosts are allowed to connect to ports
             forwarded for the client.  By default, sshd binds remote port
             forwardings to the loopback address.  This prevents other remote
             hosts from connecting to forwarded ports.  GatewayPorts can be
             used to specify that sshd should bind remote port forwardings to
             the wildcard address, thus allowing remote hosts to connect to
             forwarded ports.  The argument must be ``yes'' or ``no''.  The
             default is ``no''.
