Well, I ran the program on the Win10. All ports seemed open. I checked all of the single range ports (I wasn't going to check all 100 of the 2300-2400. I just did 2300, 2301, 2302, 2303, 2400, and 2399) I didn't check the Win8 computer. I'm pretty sure that if I switched the port forwarding to the Win8 then checked the ports I'd get the same result. It's fairly obvious that, for some mutant reason, our setup doesn't allow us to play. I said that it had worked before, but that was probably three years ago. Since then we've gotten new computers, added landline phone service through our cable internet company (therefore received a new modem) and added new systems to the network (new computers and new gaming consoles) so I've gotten new routers with more ports to accommodate the extra hardware. There's no way I can remember what setup I was using when MTM2 "worked." I guess this one goes in the unsolvable category. Thanks for the help, though.

Ah so basically you did change the hardware, that's important. The previous hardware might have been better made to deal with such issues.
Based on what you just said above I think the problem is indeed the modem/wifi thing. As I have mentioned, there are people with particular modem/wifi/router that will not allow them to join a game unless they do port forwarding or open the DMZ. In my case I don't have that problem because my router deals with such situations a lot better.
As a last desperate attempt, you can try to do the port forwarding with the host and open the DMZ on the joining computer, while using only the modem and nothing else. But ultimately it simply sounds like the only way to get this fixed is by using different hardware, which obviously involves money.
