I'm new to Cisco...and need help with configuring my new Cisco 881 Router with my existing ADSL modem.
At the moment, i am connecting to the internet using tp-link modem router, all PPPoE/DHCP/Wireless is set up there...and that connect to the switch where all my computer connected to.
Now i want to connect this new Cisco Router to it to basically do the firewall/filtering/dhcp...leave the authentication thing on my Modem.
Can i get a head start what to configure here on the cisco? since it does not work as easily as other Router where I can just plug a cable from modem LAN to Router LAN..
Much appreciated with the help!
