paradas en cisco 827

A ver si alguien me echa una mano pues tengo perdidas de conexión de adsl .Cada 15-30 minutos en el terminal aparece:

Interface ATM0, changed state to down y tal y tal.


La configuración que tengo en el router es la sig:

scheduler max-task-time 5000

El problema viene del programador de llamadas por eso te peta cada X tiempo.

Saludos, y configuralo como viene en los tutoriales de

Pero en los manuales encontré lo mismo.

esto cortado del manual

Yo tengo esa misma config del scheduler y no se corta.

Antes tenia un 3Com812 y se me colgaba continuamente.
Lo he cambiado por un Cisco 837 con una lista de acceso capando algunos puertos que se usan para "putear" las conexiones asi como puertos que utilizan algunos virus y desde entonces va de cine.

Os paso los cambios en la config:

en interface Dialer1 añadir:

ip access-group 100 in

y en la config general añadir:

access-list 100 deny icmp any any redirect
access-list 100 deny udp any any eq 19
access-list 100 deny tcp any any eq 31 syn
access-list 100 deny tcp any any eq 41 syn
access-list 100 deny tcp any any eq 58 syn
access-list 100 deny tcp any any eq 90 syn
access-list 100 deny tcp any any eq 121 syn
access-list 100 deny udp any any eq 135
access-list 100 deny tcp any any eq 135 syn

access-list 100 deny tcp any any eq 555 syn

access-list 100 deny tcp any any eq ident syn
access-list 100 deny udp any any eq snmp
access-list 100 deny udp any any eq snmptrap
access-list 100 permit ip any any

Dime si te va mejor con esto.

Salu2.
