unable to get broadband access using via Cisco 857 ISR

Hi,

Having tried the BT supplied 2 Wire ADSL Router and not getting on all that well with it, I've been trying to configure my BT Business Broadband to work with a Cisco 857 Integrated Service Router - the one without the WiFi if it matters. The BT service is the one with the 8 static IP addresses.

With the config listed below the router comes up and the CD and PPP lights come on, I can even ping a well known address (212.58.246.94 - a bbc server), and although the first ping always fails pings 2-4 get responded to (rather odd I thought) - this is pinging from the PC being used to configure the router.

But I can't browse to any named websites using DNS, or entering an IP address.

Here's the config. Any thoughts appreciated. Thanks Geoff.
