John,

As you can see from 
<https://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_vol_nc?NEXRAD2+uni14.unidata.ucar.edu>,
 for example, we're receiving NEXRAD2 data.

The latest LDM will disallow duplicate subscriptions from the same downstream 
host. All computers that are behind a NAT will appear to be the same host. 
Could that be the problem?

What is the full-qualified hostname and IP address of your computer?
