Good day to all. I would like to filter Spanning-Tree Protocol data units, which have a common destination MAC address. Is filtering based on a destination MAC address possible, or only based on a source MAC address? Thank you for your time. - Shao Miller -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
