I have couple of PCs/smart mobiles as well as iPad and couple of stream play systems in my environment and random of wifi users, for security and without impact each other that all internal user and system are fixed IP under four VLANs/Segments by 100G/10Gbps backbone switches, all streaming player have two LAN ports, one to link to NAS system (NAS also have two LAN ports at least) for play music files, one for control and management only (no interference with each other), I can setup fix IP based on MAC in switch port (not on PulseMini like you reply) but the real issue is two LAN interface (PulseMini) only support one port active, if connect two port to same VLAN (same switch or diff-switch) or different VLAN that the network will loop with STP blocking...either L2/L3
