da tempo avevo configurato il mio 2801 come server dns e tutto funzionava molto bene
senza cambiare la configurazione, da ieri non ha più funzionato.
i client in rete non riescono ad andare in internet in quanto non risolvono nessun host
il problema sta appunto usando come server DNS il 2801 (che prima funzionava bene)
fissando manualmente i DNS del mio provider tutto torna a funzionare
ovviamente ho necessità di usare il 2801 come server DNS
ho riavviato tutte le macchine, in rete non ci sono altri server DNS ne DHCP ne conflitti di IP
il 2802 nela fa0/0 prende direttamente l'IP Pubblico statico del mio provider
nella fa0/1 rete locale con ip 192.168.0.254
Chi sa aiutarmi ?
la config usata è la seguente
