I do not want *all* packets generated from this machine to use the "em0" so= urce (so, not for outgoing TCP, for example), just generated ICMPs in reply to packets coming in on "em0". Like, exactly what the v4 stack can be told to do :-) --=20 You are receiving this mail because: You are the assignee for the bug.=
