I didn't try apache on Debian, but i issued a problem on mandriva 2005 just like ur problem
i edited the vhosts (on mandriva its /etc/httpd/conf/vhosts/Vhosts.conf, on redhat its /etc/conf/httpd.conf) so figure out which one u got). I added the directive :
Code:
NameVirtualHost 192.168.1.3
<VirtualHost 192.168.1.3>
ServerName (your virtual host server name)
DocumentRoot (the directory containing the index file)
<Directory (the parent directory of the directory containing the index file)>
Allow from all
Options Indexes Includes
</Directory>
</VirtualHost>
and it worked fine.
Hope this would help.
