XML sitemap not available with Cloudfront

WordPress version: 3.5.2
WordPress SEO version: 1.4.10

I did this:
Using the plugin on my site http://www.kenfolios.com/ .I started using Cloudfront and changed the site URL to http://cf.kenfolios.com/ so taht I could access admin section. Now the XML site map is not available at http://www.kenfolios.com/. It is available at http://cf.kenfolios.com/ but I want it at my original domain.
