Link to my blog

Hi

I have set up my wordpress blog on Bluehost. – http://66.147.244.213/~Blog

I have my main site on GoDaddy, http://www.mysite.com . I want that when somebody clicks blog.mysite.com it goes to my blog at http://66.147.244.213/~Blog but it keeps the name blog.mysite.com .

Any help would be great.

Thanks in advance,
Fab
