Hello,
I have a cisco router 18XX series with 2 fastethernet ports,1 console,1 AUX. ISP has dropped 1 ethernet cable to branch office for internet connection, I want to configure a PPPOE on ethernet interface to connect to internet.
Can anybody link me to proper explanation doc's or book, for better troubleshooting and configuration.
Thanks.

You may need to configure speed and duplex on the interface.
Also
interface FastEthernet0/0
ip nat outside
is not needed. The actual interface is Dialer.
ip route 0.0.0.0 0.0.0.0 Dialer1
Also not needed. Done with ppp command.

Note the vpdn commands are NOT needed.

That is what the document is all about.
Use:

ip tcp adjust-mss 1452
not needed:
ip mtp 1492
dialer idle-timeout 0
dialer persistent
dialer-group 1
