    End result: Lightband (my new ISP) uses a double-NAT for residential accounts, with no provisions for forwarding port requests through. I know it can be done (I've done it), but that would be a lot of grief for them to manage. I guess the upside is for all of those poorly protected home systems, this does make for a major headache for the script-kiddies out there.

    End solution for me, my account was moved over to the commercial side. Everything IMMEDIATLY started working correctly. As I was not aware of the new ISP (or any other provider) doing a double-NAT, it never occurred to me. When I set up a second router that I know worked properly but would not forward the ports, something else was going on.
