[Zope] running zope behind apache

I configured ZopeHTTPServer to run on 127.0.0.2 port 5000 (as suggested in one of the example scripts) and used mod_rewrite and mod_proxy to route requests from http://website/zope into 127.0.0.2:5000. That works but all subsequent links (like on the main manager screen) are pointing to 127.0.0.2:5000, which the browser can't see. Am I missing a configuration option? thanks Kevin
