I am new to the community & new to Zimbra too,
I am trying to install the Zimbra in the testing environment before deployment, so I need lot of help.
My scenario is,
Zimbra mail Server Along with DNS should work behind the Firewall/Router
Firewall/Router IP Address 192.168.0.1/24, With WAN IP 184.108.40.206
DNS Server IP Address 192.168.0.10
Zimbra Mail Server IP Address 192.168.0.20
Now the question is, how do I configure DNS Server to serve internally as well as Publicly for Mail Domain name resolution.
I am about to configure DNS using Oracle Linux with Bind 9
I know NATing PATing port forwarding concepts & read lot of articles about Split DNS but all of them trying to install DNS on Zimbra Server.
Any Help would be greatly appreciated.
