(PM) SMURF Filter

I'm currently being smurfed to death.
Attack is using one of my downstream customers networks as the amplifier.
The attack is using 70% of my bandwidth.
The customer has an IRX112 which is billed as a "FireWall Router"

Livingston Tech support has refused to help.
They will not help with writing filters for customers or provide examples
for "Legal Reasons"
A call to my sales rep has also not resulted in any action.

I need an example of a filter that will stop someone outside their network
from pinging the broadcast address.

Is there a decent primer on Livingston Filters with examples and comments?

The one on the web site stinks.

The other option is to pull the expensive "FireWall Router" and replace
with a simple Cisco 2501 and put in the no ip-directed broadcasts command,
and go to bed.

Comments, criticisms and suggestions welcome.
