I don't think he wants to forward the traffic between those interfaces, though; just dump them all together. I'm not sure, though. If I'm right, I don't think tcpdump can do that directly. One idea might be to run a firewall to choose the packets and to forward a copy to a dummy interface that can be monitored. -- Lowell Gilbert, embedded/networking software engineer, Boston area http://be-well.ilk.org/~lowell/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
