You can't do it directly, you'll need glue between the two.
If MS SQL can open ODBC data sources, you could setup Firebird to listen to
ODBC, and pump data between the two that way.

If you need to pull data from MS SQL into Firebird, you might need a
table(in Firebird) to indicate your request. MS SQL then looks at this
request table(via ODBC), processes requests, and pushes results back into
your Firebird DB (via ODBC)...

There's lots of ways of doing it! Let us know how you go!
