This is my modem/router combo: http://www.amazon.com/gp/product/B0040IUI46/

This is as close as I've gotten to working settings: https://www.dropbox.com/s/29eujfbm8l0cgo3/Screenshot%202014-03-23%2019.50.21.png

Ports were tested with http://www.canyouseeme.org/

I am certain something is wrong and that it isn't my fault. With the above configuration, port 22 is open, as you'd expect. If I try to open more than one port, though, I'm SOL. If I check the Enable box on Port 80 below, only port 22 will stay open (port 80 will simply time out). If I try to open a range of ports (ie same settings as above, but start and end port are different), canyouseeme will give the error "Connection refused." If I make myself the DMZ host, though, all ports are open as they should be.

This is infuriating. what do
