NAT en cisco

[diegosf]

Buenos días.

Tengo configurado un router 1801w en pppoe con una ddns (llamémosla ip.noip.org) y varios puertos nat abiertos a diferentes servidores. Si intento acceder desde fuera del router a dichos servidores, funciona perfectamente (ej: ip.noip.org:22). El problema viene cuando intento hacer el mismo acceso (ip.noip.org:22) desde la lan, ya que no me deja. Como se puede abrir un puerto para que sea accesible tanto desde fuera de la lan como desde la misma? Dejo la configuración del router.
