Redirecting pages from the root folder to a subfolder

Question

I have a Joomla site in the root directory of my domain, and I have a forum at /forum subdirectory.

How can I redirect visitors from the main site to the forum, continuing to have the possibility to access the site from a link at the forum?

Example:

http://example.com 

redirected to

http://example.com/forum  

, but I can access the main site by the link

http://example.com/index.php
