DMR with a read only link

Ianp

We are currently configuring for production and test environments. The prod environment is going to use DMR over MNR, because it appears to be the better technology for now. However, we want a test broker to be able to tap into the prod DMR network via subscription, but block publishing to the prod environment. Essentially, we want to pull prod data into test, but only as needed. Running a constant bridge isn't desired.

Does anyone have a good idea on how to accomplish this? We are using the standard pub sub broker for now, with plans to move towards enterprise eventually. We just need to get the basic things setup first
