I'm trying to allowing a set of MACs to hae TCP access to ports 135-139 on a subnet. However, in the filter setup, you can only specify one MAC address. How do I allow multiple MACs to access but reject/drop the rest? I tried adding separate rules that allow a MAC (accept and passthrough) but as soon as I add one, it allows all. I'm not sure why. If I say drop all without a specific MAC, it will work.
