It's said that a problem changes in type when it chanegs _enough_ in magnitude. I suspect that it won't be another 12 months before a router with both those knobs is _required_ to meet the (new version of the) Router Requirements RFC, much less to actually _get_ a connection. If you can't filter the appropriate stuff, get the hell off _my_ Internet. :-) Cheers, -- jr 'wanna see the Bill of Sale? ;-)' a -- Jay R.
