How to prevent broadcasting between two NICs in Windows XP
-
I would like to know how to prevent broadcasting between two NICs (NIC X 192.168.xx.1, NIC Y 192.168.yy.1)in Windows XP? I have a PC with two NICs in different VLAN. I found that many traffics in 192.168.xx.0 are generated by ip address of its NIC Y 192.168.yy.1. The source mac address of the traffics are its NIC X. The destination of the traffics are mac address FFFFFFFFFFFF. So I would like to prevent it! Please help!

Which broadcasts are these? i guess it will be your normal "NetBIOS announcements". If possible (and wont break anything), remove the "client for windows networks" on it.

Is it can prevent NIC X to forward the traffic that the NIC Y 192.168.yy.1 to send packets to 255.255.255.255? Please help!
Well.. how do you see that this broadcast is going to the other subnet? It would be very stupid for Microsoft to broadcast your presence coming from an IP to a network which will only route it onwards. A packet of 192.168.xx.1 will never arrive anywhere on 192.168.yy.0/24 .... How are you determine the delivery of this packet? Are you using a sniffer?

Use router instead of 2 network card. Router will block broadcast by default.
