It's not advised to have a firewall running on the Zimbra server. Your Zimbra server is, however, behind a firewall whether it's on the same server or not. You should remove the public IP from the hosts file, pass the correct ports through the firewall to the private LAN IP and there should be no problems if your LAN IP can be resolved by a LAN DNS server.
