Linux: SSH GatewayPorts

sshd reads configuration data from /etc/ssh/sshd_config (or the file specified with -f on the command line). The file contains keyword-argument pairs, one per line. Lines starting with '#' and empty lines are interpreted as comments. Arguments may optionally be enclosed in double quotes in order to represent arguments containing spaces. - 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 allow remote port forwardings to bind to non-loopback addresses, thus allowing other hosts to connect. The argument may be 'no' to force remote port forwardings to be available to the local host only, 'yes' to force remote port forwardings to bind to the wildcard address, or 'clientspecified' to allow the client to select the address to which the forwarding is bound.
