This does not make sense to me. What do you expect the "tablearg" to be in the second line you listed? That keyword is used to apply the output of an ipfw table lookup, and you haven't used an ipfw table before that line. If you want table(<X>) to give back a fib to use, then you need to do that lookup before you do a setfib action. On the other hand, I don't see any point in doing that, because there can only be one result for a given address in your table(<X>), so there's no reason to have more than one FIB. -- Lowell Gilbert, embedded/networking software engineer, Boston area http://be-well.ilk.org/~lowell/ _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
