Do you -
1. Have (say) two firewalls in HA config?
2. Back your firewall with routing based measures, S/RTBH, blackhole communities your upstream offers, etc [the standard nspsec bootcamp stuff]
3. Simply back the firewall with a netflow based device?
4. Estimate that the risk of a DDoS that exceeds your firewall's rated capacity is extremely low? [and yes, 150k ++ connections per second ddos is going to be massive, and relatively rare for most people]
