A quick note:

If you find yourself having problems from this netblock, please contact
either jmh at msen.com (me) or noc at msen.com.

We currently cannot disable directed broadcast due to a NASTY bug
in the packet forwarding code of the Proteon routers we use on our
backbone.  We are working with Proteon to solve this issue.

(I'm also trying to figure out if the issue is worth posting to Bugtraq.)

In the meanwhile, we have implemented blackhole routing for the subnets
that seemed to be at issue.
