| Subject: | [Snort-users] Strange portscan traffic with dest of 169.254.x.x |

For the past couple of days, I have been seeing some very strange portscan
traffic coming from internal addresses and going to the internet. The Snort
box I have been getting these alerts on is sitting just behind our Internet
firewall. I have attached a screenshot of the alert.
It's odd for a couple reasons. First, why is 169.254 traffic even getting
routed to our external firewall. This is probably something I need to discuss
with our network admin. That just seems weird to me. Second, if I am reading
the alert correctly, it looks like the computer is scanning itself for NetBIOS
and SMB ports. I was just wondering if anyone else has seen anything like this.
