    Default Split-DNS scenario ok if webmail-access for external mail-users is required ?


    we intend to install Zimbra in a test environment behind a firewall in a DynDNS domain with NAT.
    Do to different reasons, we will receive and send our mails through an ISP (external mail domain).

    External users should be able to access the Zimbra-server by typing
    ( is hosted extenally)

    Is your Split_DNS scenario as well recommended for such an environment?

    Thank's a lot you for any feedback!

    If you are behind a NAT router then a Split DNS is required for resolution of the Zimbra server LAN IP, so the answer to your question is yes.
