I don't know of any, but if you feel adventurous (and you will since
this is probably not very secure), you can write/use a CGI script
that, when properly invoked, does this. You could configure Apache to
protect the CGI script via authentication. From the CGI script is not
very difficult to extract the client IP address and modify the
firewall via iptables.
