Another thought - 0.255.255.255 isn't a valid broadcast range (0 is not 
allowed in the first byte of an IP address), so the fact that this does 
something may in fact be misleading. I'd try using the default broadcast 
address for your own IP address and see what that does.

That may in fact be enough to make things work in your situation, unless 
you expect to have multiple IP subnets on the same network.
