Cisco 877 e ip fija con ONO

Hola superllo, tengo contratada una ip fija 62.x.x.x. En mi caso funciona pero ono le da siempre una ip del rango 84.x.x.x que son dinámicas. Con otros router cuya administración es web va de maravilla. El caso es que necesito hacerlo funcionar en un cisco 877.

muchas gracias por la contestación

Hola ahora estoy probando con un cisco 1720 y el problema es que no me asigna ninguna ip. Os muestro la version, configuracion, interface y respuesta del servicio dhcp

Hola Omg78:

Logre hacerlo funcionar con un router cisco 1811 con la instrucción "mac-address xxxx.xxxx.xxxx" para clonar la mac del router que te da ONO (nunca la del cable modem).

Con el cisco 877 fue imposible.

Te copio la versión del hardware cisco 1811
