Subject: Re: multicast: bug or "feature"

        From looking at the code, it appears that validate
source is failing just because of the rp_filter. Do you have
rp_filter set to nonzero?
        If so, it may do what you want just by setting that
to 0:

sysctl -w net.ipv4.conf.all.rp_filter=0

                                        +-DLS
