It very well could, although I really don't know the right answer.  That's
why I'd recommend only redirecting a specific set of dst addresses.

A better solution is to not redirect *any* addresses and fix customers'
settings as they call tech support.  It's a short-term pain, but certainly a
lot better than trying to maintain an elaborate facade of routing tricks.
