    Hello Andy:

    I wanted to do something similar and when I realized that ip6fw didn't have
    such option, I asked for it on the Kame mailing list, but they answered me
    that they didn't see it as a feature demanded by the community so they
    didn't have any plan to implement it on the short term.
    (Anyway I think it shouldn't be hard to add such feature,
    but I'm a bit lazy :)

    You can ask for it on Kame mailing-list again (because I ask for it a long
    time ago and it may have been already implemented, I don't know). Also I
    think that there are implementations of something called "source base
    routing", but I don't have experience with that.

    Cheers.
