Some of our log entries contain MAC addresses, like this:

Apr 20 10:15:35 foo kernel: IPT IN_FIREWALL: IN=eth1 OUT= 
MAC=00:30:48:11:94:e5:00:d0:ba:45:ec:25:08:00 SRC=XXX.XX.XX.XX 
DST=XXX.XX.XX.XX LEN=40 TOS=0x00 PREC=0x00 TTL=48 ID=0 DF PROTO=TCP 
SPT=1572 DPT=1080 WINDOW=32430 RES=0x00 SYN URGP=0

While others don't:

Apr 14 07:55:35 foo kernel: IPT FORWARD: IN=eth0 OUT=eth1 
SRC=XXX.XX.XX.XX DST=XXX.XX.XX.XX LEN=48 TOS=0x00 PREC=0x00 TTL=127 ID=225 
DF PROTO=TCP SPT=1047 DPT=37 WINDOW=64512 RES=0x00 SYN URGP=0

I see the "OUT" field in the latter contains "eth1" instead of a MAC
address.

Can someone elaborate on the difference here? Thanks.
