[Zope] Securing Apache w/ Zope?

hi, I have a site that is split of from Zope by Apache, it's a MailMan site. http://www.x.com/this/that I need to secure it from public access, but I don't want to create accounts in Zope, then accounts in an Apache realm. Can I make the Apache site go through Zope's authentication OR restrict access by IP subnet in Apache? Thanks, j. -- ...................... ..... Jason C. Leach ..
