(There's some hints as to the priority being required in the > IP command reference) ip rule add lookup 256 from 0.0.0.0/0 type blackhole or replace "lookup" with "table", same thing. If you use priority, you are affecting the location of that rule in the rule search. In the above case, it should blackhole everything, unless there are any "ip rule"s with a priority below 256. This is in theory, I didn't want to try it on my one linux box.
