I'm based in the UK, and we have recently acquired VDSL FTTC Fibre optic connection. We are currently using the provider supplied VDSL modem and wireless router.
We want to use our Cisco 877 instead of the wireless router. Apparently we can't get around using the supplied VDSL modem. I've found configs on the internet for how to do this, but I cannot seem to get it to work. Effectively we've configured the router to use FastEthernet3 for the WAN connection, which is also configured with the PPPoE settings required. We're going to use FastEthernet0 to connect to our internal LAN, with NAT configured on these two ports.
Has anyone had any success with this, or am I attempting something which is not possible?
