Ok, so trying to port forward.
My ISP apparently gave me one public IP address (which my router has) and I've port forwarded the router (which is an Arris, btw) to point incoming port 20090 into local port 80 (I will explain why not 80 and 80 later.)
Running CanYouSeeMe.org on 20090, however, gives me "Connection refused", (as does running ANY other port, even closed ones).
However, running CanYouSeeMe.org on port 80 gives me "Connection timed out". Strange.

Please answer these question:
* If canyouseeme replies "refused" to all but to one it replies "timed out", does that mean my ISP blocks that port?
* My traceroute shows that it only takes one hop to get to my IP. Doesn't even go to the router. What does this mean?
* Is it OK to turn off NAT on my modem (it's a modem + router)?
