It is triggered when the link goes down, as expected, but not when I just change the mark and move the flows to another interface.

Does this mean that even when using SNAT, the old mapping is deleted and a new created? And does this event not notify conntrack? I have so far used conntrack -E to monitor changes to nat, but that is perhaps incorrect? -Kristian -- 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
