Using SDM (since i'm new to cisco and don't understand all the internal gubbins yet!) I'm trying to connect an 877 onto BT broadband. I can get as far as having a WAN IP address allocated and have entered the DNS server details from the old router yet SDM test connection fails at the DNS ping stage. Plus pinging DNS entries (e.g. www.bbc.co.uk) time out. Can someone give me a clue what to do to solve this... or if someones got a working BT connection send me the details of how they configured the router.
