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.
You may need to configure speed and duplex on the interface.
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.
