Can the extention (content.php) bee changed?

That's exactly what I want. I don't want to disturb my existing forum structure. Hopefully this is possible.

There's lots of posts in the forum pointing to other threads that contain the whole url so moving the forum directory isn't an option

This isn't a coding forum, but you can always accomplish this in .htaccess using

RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ forums/content.php [L,QSA]

Then you need to have a plugin check the $_SERVER['PHP_SELF'] to 301 from forums/content.php if we accessed it directly rather than through index.php.

if (THIS_SCRIPT == 'cms' AND strpos($_SERVER['PHP_SELF'], 'index.php') === false)
{
vb4_301_redirect_function_if_one_exists_else_write_one(str_replace('forums/content.php', 'index.php', $_SERVER['REQUEST_URI']));
}
