Hi Trina, The LDM uses TCP/IP protocol, all traffic is on port 388, and you will need to allow our domain mask as we run a cluster and it is dynamic, so you will connect to a number of machines in our network over time. The IP mask you will need to allow is: 128.117.140.* Now if you need a backup feed, we can address that, and determine the IP(s) of that source.
