With all due respect, this is crazy talk. ;-) It's circular logic,
or something. When a dns reply (or http reply, or echo reply, etc) is
queued for delivery, it does not HAVE a source address.
A reply almost always does (because it is a reply on an existing socket,
which is associated with a single local address). Outgoing requests
typically just bind to INADDR_ANY, but some software (such as IIRC BIND)
bind to each address individually.
Daniel's problem is that DNS replies to requests that come in one
interface (the one lacking a default route), are being returned from a
different interface. How does that fit with what you say here?
My basic contention here is that policy routing is for routers. It
can't help Daniel, it can't help anyone with multi-homed server
routing issues. Am I wrong?
