Robert,

As long as traffic can flow bidirectoinally through port 388, the LDM
will work.

Are you giving us the IP of your LDM machine for a particular reason?
If you are feeding from a Unidata university LDM, you will need to inform
them of your name/IP change.  Also, both forward and reverse name
lookup needs to work before the LDM can operate like it designed to.
