Modificar .htaccess para redireccionar urls de foro phpbb

[Nicocoki]

Buenas a todos.

Ando buscando la manera de redireccionar las URL de mi foro hecho en phpbb, ya que activando los plugins de SEO me crea 2 url, la dinámica y la amigable, y google por ello me penaliza, los plugins para evitar contenido duplicado no hay manera de que me funcionen.

Actualmente necesito redireccionar las url:

http://www.miweb.com/topic1111.html

hacia:

http://www.miweb.com/esta-es-una-pagina-ejemplo.html



La primera URL que os expongo es actualmente hacia donde se redirige una url tipo:

http://www.miweb.com/viewtopic.php?t=3256&p=19517


Os añado mi .htaccess para que veais que hago de incorrecto ya que no logro la manera de dar con ello.

Código:

    # You may need to un-comment the following lines
    # Options +FollowSymlinks
    # To make sure that rewritten dir or file (/|.html) will not load dir.php in case it exist
    # Options -MultiViews
    # REMEBER YOU ONLY NEED TO STARD MOD REWRITE ONCE
    RewriteEngine On
    # Uncomment the statement below if you want to make use of
    # HTTP authentication and it does not already work.
    # This could be required if you are for example using PHP via Apache CGI.
    # RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
    # REWRITE BASE
    RewriteBase /
    # HERE IS A GOOD PLACE TO FORCE CANONICAL DOMAIN
    RewriteCond %{HTTP_HOST} !^www\.miweb\.com$ [NC]
    RewriteRule ^(.*)$ http://www.miweb.com/$1 [QSA,L,R=301]

    # DO NOT GO FURTHER IF THE REQUESTED FILE / DIR DOES EXISTS
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule . - [L]
