Stopping IP croadcasts from reaching a device
I am testing an IP device on our LAN and need to stop all IP broadcasts such as browser announcements from reaching that device. I did it by putting a router inbetween our LAN and the control network that this device is on and this worked fine. My question is: Are there any other ways of doing this without having to segment it with a router? I think that maybe a VLAN might be able to accomplish this using a Cisco Catalyst switch but I'm not positive. Could someone verify this for me and also suggest any other options or switch brands (If it is possible to do it with a switch at all) that might work? This device still needs to be accessible to all traffic specifically destined for it but the IP broadcasts should not reach it. Thanks!

This may not work - I haven't tested it w/broadcast IP addresses, but if you are using Catalyst switch, have you tried putting an access list on the port blocking the broadcast IP?

What kind of device?
If it's a PC running winXP Pro you can run the built in firewall - this can be set to ignore pretty much anything!
