255.255.255.255

I have a piece of software that is used to program telephone systems. Each phone system is assigned an IP address. buy using the 255.255.255.255 address on this software when loaded on and XP machine, the software is able to find all phone systems on the subnet (or WAN).

However with vista, it doesn't find any. Vista is blocking somehow and I don't know where to start.

Thanks for any insight.

Go to Control Panel, Security Settings, Windows Firewall, Change Settings, Exceptions tab, Add Program, Change Scope, Custom List and add 255.255.255.255 address.

Choose apply and test.

Everything will be OK in the end.

When I get to the PC I will try it. Thanks!

255.255.255.255 is not a real IP address - it is a subnet broadcast

I'm not sure if there is a real resolution here, but here are a couple of similar discussions

Googling [google]UDP broadcast[/google] gives a little better search results, but I don't see anything that's an obvious solution.

Oops, I mean that to be [google]Vista UDP broadcast[/google]
