I am seeing log file entries like this:

IN=eth0 OUT=eth1 SRC=109.74.193.253 DST=x.y.z.34 LEN=122 TOS=0x00
PREC=0x00 TTL=48 ID=49692 PROTO=ICMP TYPE=3 CODE=3 [SRC=x.y.z.34
DST=109.74.193.253 LEN=94 TOS=0x00 PREC=0x00 TTL=53 ID=41330 PROTO=UDP
SPT=34679 DPT=53 LEN=74 ]

This is found on our gateway host.  eth0 is the WAN i/f, eth1 is the
LAN i/f.  Our netblock is x.y.z.0/24.  Can somebody tell me what this
record is?
