Why I cannot see my site collection from internet?

Question

I have a site collection under /sites and I'm extending the whole web application to be mapped to an specified valid static ip address.

from a remote computer with internet access i cannot see the site collections under \sites but I can see my default.aspx webpage of root website.

what might be the causes of this problem? do i forget something? what kinda things I have to keep in mind when thinking about accessing a share point site from the internet ? or does it something to do with ISA server ?

Answer 1

Did you configured properly AAMs? Did u check your DNS records, etc.? what do your publishing rules say? do you use any proxies on your browser?

From your message it seems you extended by using IP instead of Host names, could you provide more details?

Answer 2

Do you have anything specific on those sites (web parts, master pages) that might causes this? Can you access http://server/sites/thesite/_layouts/settings.aspx? If you use Fiddler what kind of request/responses do you get? 401's, 404's??
