I have a customer that is a car dealer. They currently have an ADSL line connected to an MPLS network owned and run by Honda. This is purely to connect to Honda systems and does not allow any sort of Internet access. They are having a second ADSL line install which will be connected to the internet. I need to set thier network up (it only consists of 4 pc's) to allow the machines to connect to both the internet and Honda's MPLS network. They currently have a Cisco 800 series router on the MPLS line. How can I do this with a degree of relative ease?
