I just installed a new server in my small office (server + 4 workstations). I also have cable modem internet with a fixed IP. The address scheme for my server is 10.0.0.X, the router is an older Linksys with the 192.168.1.1 address. I can not get the router,server to pass signals to the cable modem although each is working properly. The Linksys router only provides wireless access outside the office network and thus is not integral to the network and is really an access point only in function. What would be the simplest solution to the problem? And one last thing, the "server" is not a full-blown rack server, just a I-7 processor PC with 8G memory running mirrored drives and Windows server 2008 Enterprise, so the server has only one ethernet connection which runs to a Gigabit Switch, which connects to all the workstations and the Linksys. The WAN port on the Linksys connects to the cable-modem.
