htaccess a web.config

[Seimundo]

Necesito ayuda para pasar estas lineas a web.config para que pueda leerlo el iis, llevo probando una semana y me da fallo en alguna linea o no se.

Options +FollowSymLinks +ExecCGI

AddDefaultCharset utf-8

<IfModule mod_authz_host.c>
<FilesMatch "\.(lock|conf)$">
Order deny,allow
Deny from all
</FilesMatch>

<FilesMatch "pre_.+\.php">
Order deny,allow
Deny from all
</FilesMatch>
</IfModule>


<IfModule mod_rewrite.c>
RewriteEngine On

# Rule to test if rewrite module is available during
# the install process
RewriteRule test_rewrite1\.txt test_rewrite2.txt

# uncomment the following line, if you are having trouble
# getting no_script_name to work
#RewriteBase /

# we skip all files with .something
RewriteCond %{REQUEST_URI} \..+$
RewriteCond %{REQUEST_URI} !\.html$
RewriteRule .* - [L]

# we check if the .html version is here (caching)
RewriteRule ^$ index.html [QSA]
RewriteRule ^([^.]+)$ $1.html [QSA]
RewriteCond %{REQUEST_FILENAME} !-f

# no, so we redirect to our front web controller
RewriteRule ^(.*)$ index.php [QSA,L]
</IfModule>

Si podeis echarme una mano en la medida de lo posible os lo agradeceria mucho.

Un saludo
