Thank you for your reply.

Let me try to elaborate it clearly,

Switch 1
Default VLAN 1

port 1(for a router), 2 (HyperV Host) and 3

VLAN 2 Guest VLAN
port 5

VLAN 3 STAFF

Port 6

VLAN 2, Guest cannot access other VLANs but can access to DHCP server, DNS, and internet access.

So, can you please help me with the complete ACL syntax?

Thank you
