Forum Wanting the forum to load ONLY within the webpage, not stand-alone
 

Hey guys,

I'm working on my website/forum at the moment, and I was quite happy to be able to get the forum within my webpage, instead of just using sitename.com/forums

See below:
http://enterstainment.com/forum.html (forum is closed at the moment, but you can see the forum position within the site)

I like it because it keeps to the colour scheme of the site, and already has the banner.

How would I stop people from loading http://enterstainment.com/forums/
That's where the direct link is, and if you go there, you can see there's no banner, colour scheme, or links to the other website components.

Additionally, if I make the forum accessable only by the forum.html entension, does this mean that google won't index my pages, because everything is on one page (forum.html)?

If that's the case, is it possible to allow search bots access to the forums directory, but not typical users? Additionally, forum.html is reading the forums directory to display vBulletin, so I need it to be able to read the forums directory or forum.html wouldn't work either.

I hope you understand what i'm trying to achieve, and I hope it's possible.

Thanks.
