Maybe I'm just blabbering here, but I have it set up so that my router is AFTER my obi device. Why don't you try that first? I have a 202 device, just FYI, but I have it set up, so that my modem connects to my obi, and my obi then connects to my router and everything else is after that. That way I can even turn my router off if I want to without any issues for my obi, so that I'll always get my calls. Just a thought...
