I'm in the planning stages of my ZCS installation.
This is the configuration I would like to achive:
Zimbra (IMAP,POP,WEB, MTA) Proxy ---> Firewall ---> Zimbra Server
Zimbra Proxy will sit on a public subnet 220.127.116.11
Zimbra Server will sit on a private subnet 10.1.2.3
The idea is for users inside and outside the network to be able to pop or imap to their mailboxes.
Moreover, for both, the front-end proxy and the back-end Zimbra server, I will like to configure each on a 2 node RedHat Cluster for high availability.
So there will be a 2 node cluster for the proxy and another 2 node cluster on the backend for the zimbra server.
Could you point me to documentation I could read to achieve this?
Or if you can reply with some ideas on how to do this, that would be great too :-)
Thanks in advance for any help on this.
