"Is there a way to connect the blog sections among the sites?

I mean linking the ‘Posts page’ set from the Reading Settings.

Settings >> Reading Settings >> Front page displays,
Front page (works, as it’s the root directory)
&
Posts page (does not work – redirects to main page).

Using MSLS 0.95 and WP 3.3RC2"
