Here's the situation:
I have a server computer with two NIC's. One goes to the DSL modem, and one goes to my LAN. It, like all the computers on the LAN, is running WinXP and ZoneAlarm Pro.
WinXP on the server computer shows three networks:
1) The modem to the ISP. This gets a dynamic IP from the ISP.
2) The server to the modem. This shows an IP of 169.254.137.126, with a subnet mask of 255.255.0.0.
3) The server to the LAN. This shows an IP of 192.168.0.1, with a subnet mask of 255.255.255.0.
The problem:
When I start up my client computer, ZoneAlarm pops up an alert that says, "The firewall has blocked Internet access to your computer (NetBIOS Session) from 169.254.137.126 (TCP Port 3274)(TCP Flags: S).
What the heck is this? I thought the NIC with that IP address was separate from the LAN...it has a different IP and subnet mask. So what is this access that the client's ZoneAlarm has blocked?
Should I do anything about it? I was wondering if I should tell the client's ZoneAlarm to accept traffic from the 169.254.137.126 IP, but on the other hand, letting it block it doesn't seem to be causing any harm. I can still access the internet, and all the resources of the server (drives, printers, etc) just fine.
Pretend I know nothing about this subject (close to the truth), and explain this to me, please.
