Titolo: 1605R e pppoe

Salve,
ho con me un router Cisco 1605R con IOS 12.2(15)T9 e con 24 mb di ram e un 
modem ethernet Ericsson HM220dp che lavora in modalità bridge solo in pppoe.
Ora vorrei utilizzare il suddetto router per gestire la connessione adsl e 
condividere la stessa nella mia lan.
ho certato via internet qualche configurazione ma non mi funzionano quindi 
provo a chiedere aiuto a voi o al massimo a qualcuno che è già riuscito 
nell'inpresa.
per non dilungarmi troppo vi posto le parti cruciali della configurazione 
del router:
[....]
vpdn enable
vpdn-group 1
 request-dialin
 protocol pppoe
interface Ethernet0
 description Interfaccia LAN
 ip address 192.168.1.253 255.255.255.0
 ip nat inside
interface Ethernet1
 description Interfaccia WAN ADSL
 no ip address
 pppoe enable
 pppoe-client dial-pool-number 1
interface Virtual-Template1
 no ip address
 ip mtu 1492
 no peer default ip address
interface Dialer1
 description Dialer WAN ADSL
 ip address negotiated
 ip nat outside
 encapsulation ppp
 dialer pool 1
 dialer-group 1
 ppp authentication chap callin
 ppp chap hostname *****
 ppp chap password 0 *****
 ppp pap sent-username ***** password 0 ******
ip nat inside source list 10 interface Dialer1 overload
ip classless
ip route 0.0.0.0 0.0.0.0 Dialer1
no ip http server
access-list 10 permit 192.168.1.0 0.0.0.255
dialer-list 1 protocol ip permit
[...]
Con questa configurazione ogni tanto il router riesce a collegarsi (ma molto 
raramente) e facendo "show vpdn" da la sessione pppoe UP.
Pingano domini o indirizzi ip fuori dalla mia rete ho sempre risposta sia 
dal router che dai pc in lan, però ho notato che dai pc della lan navigo 
solo in certi siti, per esempio google lo carica senza problemi, anche 
effettuando qualche ricerca. ma gli altri siti riesce a risolvere il dominio 
ma non riesce a caricare la pagina.
Ho provato collegandomi  a server irc e via telnet dal router mi connetto 
senza problemi ma se invece lo faccio da un pc oltre alla risoluzione del 
dominio non va avanti.
Secondo voi cosa può essere?

Allora così funziona, ma continua a darmi problemi con la connessione con il 
provider, cioè funziona 1 volta si e 50 no.
facendo "debug ppp authentication" mi da questi messaggi:

così all'infinito.....
cosa può essere?

dopo svariate prove e letture del sito della cisco penso che tutto 
l'inghippo sia sul listato che vi posto sotto:
ho fatto il debug delle negoziazioni del protocollo ppp, nelle varie 
richieste tra client e server appare più volte questo "TIMEout: State 
ACKrcvd"
arrivato a questo non so più che fare.
qualcuno ha qualche idea?
