    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''.
