linking external DNS with account in WHM/cPanel
Hey, I just set up a VPS server that runs WHM and cpanel. I am trying to route a domain name, let's call it tempdomain.com, to the HTML files of an account, let's call that webapp.com. The domain name is managed by dreamhost, the VPS is with a local company. So once I point the DNS entry to my VPS nameserver, then what?
That domain name is temporary.. so I don't want to create an account in WHM called tempdomain.com, I want to just leave it as webapp.com. The support person at my hosting company says that's not possible, that I would need to create an account named tempdomain.com within WHM for that connection to happen, but I'm not sure I believe that. Is there some way to route that incoming domain name to a differently named account? Perhaps through some A name or DNS zone tactics?
Thanks for any help!
