interface Dialer1 

ip address negotiated 

ip mtu 1492

!--- Ethernet MTU default = 1500 (1492 + PPPoE headers = 1500)

!--- Ties to atm interface. 

ppp authentication chap callin 

ppp chap hostname

!--- ppp chap hostname  

!--- ppp chap password  

!--- with the following two lines:

!--- ppp authentication pap callin

!--- ppp pap sent-username password

!--- For NAT we are going to overload on the Dialer1 

!--- interface and add a default route out 

!--- since dialer ip address can change.
