    That's handy for a network like I have. What would also be handy, is a
    sysctl like that for the client side - that tells FreeBSD to ignore the
    fact that a response is coming from a different IP than what it sent the
    request to. Yes, I know this is a security issue, and yes I understand
    the ramifications. Nevertheless, I need it - unless there is a way to
    tell redhat and solaris to always answer on the same interface the
    request came in on..
