I'm not hugely experienced with Cisco routers but I've managed to configure a Cisco 2921 with BT Infinity which works fine. I can access the web/browse etc.
The only thing I'm struggerling with, is my BT package has static IPs currently the BT Home hub dials with PPOE and the static IPs on the hub appear to be a virtual interface. Does anyone know how to configure this similar style setup on a Cisco router?
