Copy&Paste in a .htaccess:

DirectoryIndex /forum/topic.php?id=20

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} /forum/index.html

RewriteRule (.*) /forum/topic.php?id=20 [L]

Now (sorry for my bad english, im german) the topic is your forum-frontpage.. (dont forget to delete the “New Topic” links).
