I am newbie to cisco routers and I have a 1721 adsl router. I am having trouble getting the router to work. This is the configuration I am using for a static adsl connection and chap authentication: Is there any way to debug and find what is going wrong ? Current configuration : 1625 bytes ! version 12.3 service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname router1721 ! boot-start-marker boot-end-marker ! logging buffered 51200 warnings enable secret 5 </body>$N3Ph$SaRhU7HPx75lg7qc0p49e/ enable password cisco ! username cisco privilege 15 password 0 cisco mmi polling-interval 60 no mmi auto-configure no mmi pvc mmi snmp-timeout 180 no aaa new-model ip subnet-zero no ip routing ! no ip cef ! interface ATM0 no ip address no ip route-cache no atm ilmi-keepalive dsl operating-mode auto bridge-group 1 pvc 8/35 encapsulation aal5snap ! ! interface BRI0 no ip address no ip route-cache shutdown ! interface FastEthernet0 ip address 192.168.2.92 255.255.255.0 no ip route-cache speed auto half-duplex ! interface Virtual-Template1 ip address negotiated ppp chap hostname myhotname ppp chap password 0 mypassword ! interface Virtual-Template2 ip address negotiated ppp chap hostname myhostname ppp chap password 0 mypassword ! interface Dialer1 ip address negotiated ip mtu 1492 encapsulation ppp ip tcp adjust-mss 1452 dialer pool 1 dialer remote-name vivodi dialer-group 1 no cdp enable ppp authentication pap chap callin ppp chap hostname myhostname ppp chap password 0 mypassword ppp pap sent-username myhostname password 0 mupassword line ppp ipcp dns request ppp ipcp wins request ! ip classless ip http server ip http authentication local ! ! ! control-plane ! bridge 1 protocol ieee ! line con 0 line aux 0 line vty 0 4 privilege level 15 password cisco1721 login local ! end Thanks Nik
