How to restrict Alfresco Login by IP address

Hi,  I want to restrict login to alfresco from certain ip addresses only. Is there any method to do so ?
thanks and regards,
Narendra.

I'd use Apache forwarding (with mod_jk or mod_proxy_ajp) for that purpose - Apache is better at blocking IP's then Tomcat.
