Hola a todos.
en la empresa tenemos un viejo SA520 con varias reglas (Port Forwarding) para conectarse de wan a varios servicios de la lan
Lo vamos a sustituir por un ASA 5506-x el cual estoy tratando de configurar para tener todo igual así el cambio sea lo menos traumático.
El tema es que no puedo direccionar ningún puerto , por ejemplo el 80
Tengo 3 interfaces inside, serviciosweb, outside.El servidor web es 192.168.15.40 , desde mi lan 192.168.10.0 accedo perfectamente , pero de outside no puedo (error rpf-check)
He probado varios tutoriales pero nada.Tambien intente direccionar el puerto 3389 para escritorio remoto en inside y tengo el mismo error.
No se si tengo algo mal configurado de inicio.
Pego la configuracion y el packt-tracer al puerto 80
: Serial Number: JAD210105U0
: Hardware: ASA5506, 4096 MB RAM, CPU Atom C2000 series 1250 MHz, 1 CPU (4 cor
