Hello,

     Are there any security concerns about passing in
icmp traffic to my network?  I do not use NAT so
people at best will be able to map out live machines
on my network.  Is this correct, or should I be
concerned about possible attacks through ICMP?  The
only ICMP traffic I pass in is icmp-type 0,8, & 11.
Any pointers are greatly appreciated.

Thank You 
Chris
