Re: martian sources iptables

Hola,

Esto sucede cuando tu router no puede enrutar los paquetes de origen <---> destino, aun que todo este bien, un posible problema puede estar si está un router antes que el tuyo o si este router tiene la misma ip de uno de tus gateway eso causa un loop en tu router y te termina dando ese error o puedes leer también otras causas aca http://en.wikipedia.org/wiki/Martian_packet

Saludos.
