Networked hard drive rule setting?

I have bought a network hard-drive that only works if I allow all packets (bottom rule in enhanced).

I have 3 PCs (2 wireless and 1 hard) and the n/w hard-drive. From looking at the log there are loads of ethernet packets passing around from one pc to another, from PCs to the drive, plus also ff:ff:ff:ff:ff:ff packets.

Can somebody please spell out what rules I should set on each PC. I know the MACs of the PCs and the networked hard-drive.

Thanks
Ian
