[lug] Blocking ping -f with ipchains?

I am wondering exactly how I would block out icmp floods using 
ipchains. I know how to do it for specific ip's or hosts but I was 
thinking about adding a rule using the --fragment option. Would this be 
something worthwhile? Here is what I had in mind:
/sbin/ipchains -f -A input -i eth0 -p icmp -s 0/0 -d 0/0 -j DENY

Except I'm not exactly sure where to put the -f flag in the rule. Is 
there a better approach to this? Some security software that might help 
prevent floods? Thanks in advance...

Justin
