According to hc <haesu () towardex com>


Of course, egress filters don't
solve the issue. But considering most script kiddies' intelligence
level
is limited, it will help at least a bit. :-) The problem with egress
filtering is that it's mostly applicable at the end tier2+ level,
not at
the backbones, which means a lot of ISP's who are oblivious on what
it
is (or some cases where egress filter breaks their network setup).

On the subject of "help a bit", if service providers were to require,
by default, either an egress filter (correctly configured) on the CPE
router or an ingress filter on their own customer aggregation router
it might do some good ...

Cheers.
