The way we set it up, we just put a proxy in front of it that takes care
of filtering the requests. Simplest one would just pass GET queries from
"outside" (which may be a problem if you need to serve SELECT queries
via POST, see below). Of course, you could have proxy use more complex
rules and firewall according to your definitions of inside/outside.

In newer versions of Blazegraph, there's also X-BIGDATA-READ-ONLY
header, if the proxy sets it to "yes", write requests will be rejected.
This allows to pass POST requests but still have it read-only.
