redirecting .htaccess

[JohnAnn Thompson]

I am working redirecting a set of users from one site to a new site. I can use the users ip addresses for my condition statement. So far in my test I only get an enternal server error message.

my .htaccess file is as follows:

RewriteEngine on
RewriteCond %{REMOTE_ADDR} ^###.###.###.###
RewriteRule (.*) http://newwebsite.com/index.html/ [R,L]

Can someone help point me in my error? Thanks
