I can't figure this out.
Our server has three internal IP addresses on two interfaces. So we have
eth0, eth0:1 and eth1.
"Oct 31 09:24:47 mail2 kernel: FIREWALLED: IN=eth1 OUT=
MAC=00:09:5b:22:29:d1:00:06:25:e4:ed:a3:08:00 SRC=217.97.25.71 DST=192.
168.0.5 LEN=404 TOS=0x00 PREC=0x00 TTL=111 ID=40607 PROTO=UDP SPT=6022
DPT=1434 LEN=384"
In this case, destination 192.168.0.5 is on eth0:1. Yet it shows as eth1
with the eth1 MAC. This connections was NATed through the router so it
never hit the eth1 interface. Here's part of the ifconfig.
eth0 Link encap:Ethernet HWaddr 00:50:04:65:E3:1B
inet addr:192.168.0.31 Bcast:192.168.0.255
Mask:255.255.255.0
eth0:1 Link encap:Ethernet HWaddr 00:50:04:65:E3:1B
inet addr:192.168.0.5 Bcast:192.168.0.255 Mask:255.255.255.0
eth1 Link encap:Ethernet HWaddr 00:09:5B:22:29:D1
inet addr:192.168.0.32 Bcast:192.168.0.255
Mask:255.255.255.0
