We have a server with apache running on 443 as a reverse proxy to one of our servers. Trying to install Zimbra Proxy on the same server and since 443 is used by apache, it's failing with interface "in use".

Is it possible to

Use the zimbra-proxy to do what httpd is currently doing? Can I add the ProxyPass lines to the zimbra proxy config file? Where is the Zimbra Proxy virtual hosts file? This way we can kill apache, and use Zimbra Proxy to do both, proxy mail and be the reverse proxy for our other server.
Can we, using a config file, set the proxy to only bind to eth0 and not all interfaces?

Also, running latest 8.0.3 too.

Thanks. Hope someone can help.
