Problema di caricamento su molti siti

ciao a tutti,
ho da poco installato un cisco 877 al posto del vecchio linksys e da quando ho fatto il cambio di router, ho dei problemi con il caricamento di molte pagine web.
praticamente se uso il router 877 e vado sul sito della gazzetta ( come tanti altri siti tipo radio 101, ecc) mi rimane la pagina bianca del browser e non va avanti!
il problema lo fa con tutti i pc della lan (win e mac)...
ho controllato i dns, i nomi vengono risolti correttamente (sono uguali a quelli impostati sul vecchio router), ho provato anche a mettere i dns di google, ma non cambia nulla...
Non ci sono acl o simili...
cosa puo essere?
di seuito la config.

strano...
prova solo con
sempre sulla dialer0
ciao
P.S. Se hai alice, prova anche in PPPoA (mtu 1500).. perche' non tutte sono configurate con l'auto-sens del protocollo di encaps. e nel caso di protocollo errato il problema e' esattamente identico al tuo.

ho provato anche cosi, ma il problema rimane...
come trasformo la config in PPPoA?
comunque non ho Alice, ma Libero....

io non uso la p-t-p, la trovo superflua per adsl.

intanto proviamo a mettere questo nell'interfaccia Vlan1:

facciamo un reload dopo aver salvato la modifica.

ma perchè non configuri in PPPOE ???
So che su libero il PPPOA dà problemi
Inviato: mar 15 giu , 2010 11:13 pm
da zenze
Grandissimo!!! funziona!!!! grazie 1000!!!!
perche io avevo la conf in ppoe, ma se leggi sopra, una delle prove era quella di provare in pppoa...
cmq so che libero funziona in entrambi i modi, perche io a casa mia fino ad ora avevo config il ppoe, mentre a casa di un mio amico poco distante da me, ha il router config in pppoa sempre con Libero...

diciamo che per la configurazione ottimale è preferibile la PPPOE soprattutto se utilizzi il router per condividere la connessione in rete per più pc, il PPPOA libero lo consiglia solo per determinate abbonamenti con alcuni apparati.
comunque se posti una conf attuale, vediamo se possiamo migliorare qualche altro paramentro !!!
posta anche un > sh int dialer0
