El reenvío local no funciona

He intentado reenviar puertos locales a través de SSH a un host remoto:

$ cat .ssh/config
host km4ayu.com
LocalForward 29070 127.0.0.1:29070

He intentado un montón de cosas, pero ¿cómo hago para que este reenvío acepte conexiones de otros hosts en mi red local? es decir, escuchar 192.168.1.116:29070y reenviar el tráfico a km4ayu.com:29070?

Mi .ssh/configentrada de anfitrión:

Host km4ayu.com
AddressFamily inet
User kv4lq
Port 17785
GatewayPorts yes
LocalForward 3306 127.0.0.1:3306
LocalForward 17786 127.0.0.1:17786
LocalForward 17787 127.0.0.1:17787
LocalForward *:29070 www.km4ayu.com:29070
LocalForward *:29071 www.km4ayu.com:29071

Aquí está la salida de ssh -vvv km4ayu.com, usando ese .ssh/configarchivo:

Este comportamiento está controlado por la opción GatewayPorts( offpor defecto). Desde la página del manual para ssh_config:

GatewayPorts

Especifica si los hosts remotos pueden conectarse a puertos reenviados locales . De forma predeterminada, ssh(1) vincula los reenvíos de puertos locales a la dirección de bucle invertido. Esto evita que otros hosts remotos se conecten a los puertos reenviados. GatewayPorts se puede usar para especificar que ssh debe vincular los reenvíos de puertos locales a la dirección comodín, lo que permite que los hosts remotos se conecten a los puertos reenviados.

El argumento debe ser “sí” o “no”. El valor predeterminado es "no".

Tienes que poner también

GatewayPorts yes

a su ssh_configy especifique la dirección local explícitamente:

LocalForward 192.168.1.116:29070 127.0.0.1:29070
Los puertos de puerta de enlace son sí del lado del servidor. Puse esta línea y la probaré esta tarde.
También es una opción del lado del cliente.
😳 bueno, entonces, me aseguraré de configurar eso.
Configuré GatewayPorts en sí .ssh/configpara ese host. Lo intentaré ahora.
El programa que estoy tratando de usar en mi red (específicamente MovieBattles2, un mod para Jedi Academy) me da un Awaiting Connectionmensaje hasta que se agota el tiempo. No veo nada del lado del servidor de juegos.
Si lo intento (en la máquina de reenvío), nc 192.168.1.116 29070recibo este mensaje en mi sesión ssh: channel 7: open failed: connect failed: Connection refusedy la sesión nc finaliza.
Prueba también LocalForward *:29070 127.0.0.1:29070. También podría ayudar. ¿La opción original funcionó en la máquina de reenvío? ¿Intentaste volver a conectarte?
Nada ha funcionado hasta ahora en la máquina de reenvío. Volver a conectar no ayudó. una ncconexión desde la máquina que ejecuta el cliente del juego también dio el error de apertura fallida. Ahora intentando *:29070
Todavía no se puede conectar. una conexión nc también falla con el mismo dicho error en la sesión ssh.
Un cheque más. ¿ Tiene AllowTcpForwardingpermitido en el servidor?
Sí. Además, acabo de configurarAllowAgentForwarding yes
Agregar la línea LocalForward *:8080 www.km4ayu.com:80, luego intentar acceder 192.168.1.116:8080me da un error de no poder conectarme en Firefox. "Firefox no puede establecer una conexión con el servidor en 192.168.1.116".
Probé SSH desde otra Mac (que tiene MB2 instalado) con configuraciones idénticas y no pude conectarme ni siquiera usando localhost. Eso significa que no es un problema de firewall, sino un problema de SSH.
Para la pregunta editada, publique el registro detallado de su conexión ( ssh -vvv km4ayu.com)
