I am looking at these sorts of things as well:


IN=eth0 OUT=eth1 SRC=129.250.200.121 DST=x.y.z.56 LEN=96 TOS=0x00
PREC=0x00 TTL=243 ID=32285 PROTO=ICMP TYPE=11 CODE=0 [SRC=x.y.z.56
DST=88.198.155.41 LEN=28 TOS=0x10 PREC=0x60 TTL=1 ID=1968 PROTO=UDP
SPT=50131 DPT=6528 LEN=8 ]


x.y.z.56 is a disused address in our netblock assignment.  So whatever
this is it is not legit.  Does anyone recognize this?
