Hi
i've joined this forum, hoping that my problem gets solved.
iam implmenting PPPoE into the cisco 1841 router with IP address that got from ISP dynamically.
ok fine, i have configured my router with the familar command

like this

My router#vpdn enable
no vpdn logging
request dialin
protocol pppoe

interface fastethernet 0/0
ip address 192.168.1.2 255.255.255.0
no ip redirects
no shut
ip nat inside
interface fasthernet 0/1
no ip address
no ip redirect
no ip address
no ip mroute-cache
pppoe enable
pppoe-client dial-pool-number 1
interface Dialer1
description Logical ADSL Interface
ip address negotiated
ip mtu 1492
ip nat outside
encapsulation ppp
ip tcp adjust-mss 1452
no ip mroute-cache
dialer pool 1
dialer-group 1
no cdp enable
ppp authentication chap callin
ppp chap hostname
ppp chap password
ppp pap sent-username password
ppp ipcp route default
ip nat inside source list 10 interface Dialer1 overload
no ip http server

so after configuring the router with similar commands
i come accross all interfaces are up
but when iam pingging to web site or external ip address it shows me this msg
"Unrecognized host or IP address , or protocol not set

what to do please help
