cm1 initial issues

I have installed a new instance of CM1 3.2, and I can get to http://x.x.x.x:9992/Rhythmyx/ from the machine. But I can not get to the url from a remote machine using the public dns name of the machine. I am sure the dns mapping is correct since I can hit port 80 of the machine and get IIS’s welcome page. What gives?

Also what is the default username and password?
