I've got a daemon that listens on a virtual IP address, that is itself
attached to a cloned loopback interface on FreeBSD.
Packets for that daemon could be arriving from multiple physical
interfaces, and that's what's taxing me just now.
I would -really- like to be able to process those packets without
needing a per-interface thread or process (or other code changes) but it
seems FreeBSD (and Linux FWIW) will only capture packets on that
loopback IP that also -originated- on the loopback.
Does anyone know of any magic trick I can invoke that'll reveal those
packets?
cheers,
Ray
