No firewall, only the router. I am pretty sure I forwarded the port correctly, I did it the same way I have always done it. As far as I know, nothing else is using any of the ports I tried. The only thing I can think of is that the ISP is blocking port 80, which is why I tried to change ports. Only, when I tried that the whole thing broke. Is there a specific set of things I must do to change the port to something other than 80?
