I need a little help on making changes to add inter-lan communications between a few devices on my TP-Link network.

My environment is:
TP-Link Router - ER7206
TP-Link Switch - SG2218 -16 port
TP-Link EAP225 - Wireless Access Point (VLAN 30)
TP-Link TPE-TG44ES POE Switch
Synology DS218-Plus 192.168.60.2 (VLAN-60)
Mac Mini 192.168.60.21 (VLAN 60)
Macbook Air 192.16830.70 (VLAN 30 -wireless)

I now need to make changes to allow the Mac Air to access the Synology NAS. The Mac Air connects to the access point and uses 192.168.30.70

Not sure if my hardware supports this or are the changes made on the router or switch or both. The Mac Mini being on the same NAS network (192.168.30.49) works fine.

Allowing the Mac Air to connect is fine, but no other wireless devices should access the NAS - I could change the Mac Air to have a static IP.

Suggestions?
