    Default install on nat server that uses DHCP?

    I am trying to install zimbra on on an amazon elastic cloud instance.

    I have a static external ip address (elastic ip address) with a dns entry and MX records pointing to this external ip address.

    When I attempt to install zimbra, it wants to use the dhcp name of the server, which is subject to change. I see others have done this and their install breaks on a restart of their server.

    I read about the split dns setup, but this still assumes a static ip address on the server. I tried changing the domain for the install to ( but because this is the external interface for the server, the installation will not continue.

    Any ideas on how to proceed with this problem? I included the text message that zimbra gave when it could not proceed with my domain name change.
    Thank you!

    You might have a look at this thread. Several people have done dynamic DNS setups with varying degrees of success, but this thread tells you a good deal about what does and doesn't work.
