Re,

I am blocking most incoming icmp traffic:

icmp-type 0
icmp-type unreach code 3
icmp-type unreach code 4
icmp-type timex

also.. im running jail, but icmp doesn't work from there.. how could this packet get through my firewall:

Jul 17 05:12:53 ml ipmon[18381]: 05:12:52.177910 2x ed0 @0:35 p 0.so-3-0-0.XR1.ATL1.ALTER.NET -> jail PR icmp len 20 
56 icmp 11/0 for jail,3366 - 63.108.161.50,1439 PR tcp len 20 40 IN
