  As long as you know the IP OpenDNS will return, it goes about like this:

alias=ip-from-opendns,ip-for-intranet-site
(e.g. alias=123.45.67.8,192.168.1.2)

  As for "forward the client," that's a matter of the client software, 
so it only does something useful if the DNS request was via a web 
browser (returning your intranet site's IP for a request made from a 
mail/FTP client won't help anything).  I imagine you probably know that, 
but your wording was curious.
