Hola, estoy intentando configurar el cisco 877 con el SDM en modo ip dinamica, parece estar todo bien por que al hacer un test de conexion es todo ok, y cuando desde otra adsl hago un ping a la ip que me a cedido telefonica me responde ok.
Pero, pero ningun pc conctado a ese router puede navegar ni siquiera hacer ping a ninguna ip.
Paso mi config. Haber si teneis idea de que me dejo en el camino.

% Password expiration warning.
-----------------------------------------------------------------------

Cisco Router and Security Device Manager (SDM) is installed on this device and
it provides the default username "cisco" for  one-time use. If you have already
used the username "cisco" to login to the router and your IOS image supports the
"one-time" user option, then this username has already expired. You will not be
able to login to the router with this username after you exit this session.

It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.

username <myuser> privilege 15 secret 0 <mypassword>

Replace <myuser> and <mypassword> with the username and password you want to
use.

Yo creo que tiene que ver con el NAT.

Dios da ciscos a quien no tiene dientes.... Anda sacate el ccna y deja de jugar con los juguetes de los mayores...

cuando lo tengas dimelo

Hola
Bueno, te cuento, a mi me sucedia lo mismo y la solución es la siguiente:
Con el SDM entra al router y resetealo a Factory Default
Antes de empezar a configurarlo mira bien en el router de Telefónica la configuración que tiene, debes tener una Puerta de Enlace predeterminada, en mi caso es la 192.168.153.1, esa IP cuando empieces a configurar el Cisco con el SDM, introduciras los datos normales que da Telefonica de usuarios, contraseña, VPI/VCI etc, llegarás a un paso que te va a pedir el "Next Hope", es aqui donde debes introducir esa IP y posteriormente te preguntará si quieres activar o usar NAT, a lo cual marcaras que si, lo demas creo que sabras hacerlo.
Suerte y un saludo
