Only W2k and WinXP use 169.254.x.y if there is no DHCP server, Win9x
uses 192.168.*.

No thats not entirely right because the Automatic Private IP Adressing
(APIPA) Feature of Windows uses Adresses in the Range 169.254.x.y

If I remember right, setting a NIC in Windows to DHCP and there is no
Server, the IP is set to something in 192.168.*. Maybe there is Winbox
near
You spamming the line?

Hello all,

Reviewing my home office firewall logs, I noticed an
entry in which someone tried to connect to my
external interface with an IP of 192.168.50.xx. I
assume it's a spoofed address, but I just don't know
how they got it to traverse the Internet? How can that
be routed?

Thanks.
