Funny, Marius Strobl (CC'd) told me about this problem a week ago. It
seems this is a fundamental flaw in the BSD network stack in that it
doesn't keep arp-entries per-interface for all interfaces. Solution would
be to add a interface in the kernel list for which interface the arp entry
is valid - unfortunately that's not done right now.

There seems to be a solution that involves some userland daemon, but I
don't know which one. I'll let Marius answer this. ;)
