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..
