[.htaccess] Mandare in una cartella se l'IP non è 127.0.0.1

Scusate se dal titolo non si capisca molto bene il problema...
Io ho Apache che gira sul mio PC, e ci risiedono vari script che testo, in via di sviluppo, eccetera.
Vorrei fare in modo che se un utente accede dall'esterno possa visualizzare solo i contenuti della cartella public che è nella root del server (/srv/www/htdocs/), in pratica se il visitatore non ha l'IP 127.0.0.1 deve vedere solo i file in public, senza però rendersene conto (senza /public nell'URL).
Ci ho provato in tutti i modi ma non c'è stato niente da fare, sono un impedito con gli htaccess

P.S.: Qualcuno conosce una buona guida sull'argomento? Io non ho trovato niente di interessante

prova così:

RewriteEngine On
RewriteBase /
RewriteCond %{REMOTE_HOST} !^127\.0\.0\.1 
RewriteRule ^(.*)$ public/$1

Niente, errore 500, ecco il log del server

il file richiamato è il /public/file.txt.2 e ho cercato di accedere da IP-COMPUTER/file.txt.2 (da anonymouse).

Ho provato anche a mettere [L] dopo la rewrite rule ma niente.

si...scusa...hai perfettamente ragione...prova così:

RewriteEngine On
RewriteBase /
RewriteCond %{REMOTE_HOST} !^127\.0\.0\.1 
RewriteCond %{REQUEST_URI} !public/
RewriteRule ^(.*)$ public/$1 [L]

Grazie mille, appena posso proverò, perché adesso sono in montagna per le feste, e adesso sto scrivendo a scrocco dal computer della biblioteca
