Muchas gracias por responder;
Te comento como esta la situación, la interfaz del DMZ si esta conectada directamente al ASA, lo que tendría que estar detras del Router es la interfaz inside.
La IP pública del servidor es 187.161.171.55 y la privada es 176.16.10.10 la del DMZ es 176.16.10.1
Esta es la configuración que tengo, te agradézco tu ayuda.
ASA Version 8.2(5)
