Right.

I can confirm via JMX that there's no subscriber on the proxy broker.

Got it.

To some extent, it's because I'm not entirely sure what I'm doing. :)

The documentation is a little vague on why one might want dynamic vs
static. The documentation for the static configuration seemed to fit
what I was trying to do:

  http://activemq.apache.org/networks-of-brokers.html#NetworksofBrokers-Purestaticnetworks

"If you wish to completely protect the broker from any influence of
consumers on the remote broker, or if you wish to use the brokers as a
simple proxy and forward all messages to the remote side no matter if
there are consumers there or not, static networks are something you
should consider."

I'll give the dynamic configuration with a wildcard a shot now.
