Re: Disk Agent in DMZ ( DP 8.1)

My usual rule of thumb is to find out where the 'omnirc.tmpl' file is, and that is the directory where 'omnirc' has to live

You may want to look at some documentation about the 'omnirc' file in general, and backing up through a firewall in particular.  I am going to refer you to the DP 5.5 Administrator's Guide

Chapter 13

They stopped publishing the Admin Guide after DP 5.5, but, in terms of your issue, nothing new has been added in any new versions
