Impact of domain forwarding with masking on SEO

Hi,

I am considering to register a private domain for a new website of mine. I have checked out some providers, but since I already have a good hosting package elsewhere (which does not provide private registration options), I am thinking of getting a private registration at Bluerazor, and then forward it to a subdomain using the masking option.

Does anyone know, how this is going to impact search engine rankings? If I use domain forwarding with masking, is there is still a possibility for visitors to view the target domain, where the website is located?

It is very important, that the target domain (where the actual website is located) is not going to be registered in search engines.

Thanks.
