I have a question about adding a second SSL certificate to our stand-alone ZCS NE 7.1.4.

In the how-to here : SSL certificates per domain - Zimbra :: Wiki, it looks pretty straight forward.

However, it mentions needing the proxy server -- everything I've read in the forums says not to use the proxy server if you have a one-server install. Can anyone with experience with such things comment on this catch-22?

Also wondering if there is a document out there regarding adding the 2nd IP that would be required for the 2nd cert. Is it just as easy as adding it to the underlying OS (Centos 6.2) and /etc/hosts or do I need to add it in Zimbra somewhere else too?

Thanks so much!!
