RE: [FW1] How do I stop being smurfed?



The IP stack will still process the packets and jam the internet access,
before
they are dropped. So its better to have your ISP do the
shitwork than you. They probably have better resources/pipes to 
handle it.

Yep, I'm running FW-1.  I can drop the packets in my rulebase OK but
they still saturate the network in front of my box before I can drop
them.
