BIND & two interface cards

[Kevin Darcy]

For inbound queries, I believe this is the way it works automatically--
named responds to queries from whatever address the query came from.

If you want outgoing queries to use a particular address, configure it
with the "query-source" option. Note, however, that this just controls
the source *address* of the queries -- your OS'es network routing
configuration will still control which physical interface is used for the
packets.
