This sounds like an Xfinity problem to me. I am by no means a networking expert but if Xfinity could not reach the modem, which is the first thing their cable connects to, then I don't see how your firewall or unbound could be the culprit. Xfinity's first response being "it's your fault" is standard, in my experience. Allan
