I have a small network that I support that is now using a cable provider for internet service and connectivity to the server. This network has been using static IP addresses (192.168.xx.xx) for connectivity but I'm guessing that this will have to change when we going through ComCast (ISP). When I connected a workstation to the MODEM it pulled an IP of 10.xx.xx.xx. While working with one of they're first level support folks I described what needed to be done and the tech said for me to use a static IP on the server of 50.243.xx.xx. How this could work I didn't understand and proceeded to push the cut-over out until I can feel more confident with the configuration. What I'm interested in hearing back on is your thoughts on network configuration in this type of environment where we have three MODEMS in three different physical locations using an ISP to not only connect to the internet but also connect to a windows server 2008 R2.
