Domain Forwarding

I've used GoDaddy as my domain host for most of my IT career.  I am new to Comcast Business for hosting.  I received a free domain with my school's business class internet service and registered a .net domain to use as an address to point to our Google Apps for Education intranet site.  For the life of me, I cannot seem to find where I can forward my domain to my Google Sites web page.  I've done this with no problems on GoDaddy, but the domain control panel for Comcast seems very limited.  Am I missing something?
