are the 4 ips on different physical LAN cards on different physical LANs? or do the 4 cards go on one physical LAN?
“On LAN interface

if they are all separate LAN’s, i know some major disasters that try to call themselves LANs, then simple DHCP will work just setup per LAN card, but if it is one physical LAN coming into the zs box you are pretty much limited to what ppalias said.
to gather MAC ids you can use the DHCP leases section in ZS or get an app called Magic Packet and it will probe and return current MAC/IP, and as the name suggests after you know the machines it can be used to wake a sleeping pc.
