My existing network working good with OC200. where TL SG-2210MP is core switch, OC200 manage EAP225 outdoor and core switch. Pfsense is my DHCP server and it's have  two parent Interface [ ix.0(WAN), ix.1(LAN) ]

LANNET              - (VLAN ID -10)
MGMTNET          - (VLAN ID - 20)
SERVER NET     - (VLAN ID - 30)

IOT NET             - (VLAN ID - 40)

OC200, TL SG-2210MP, EAP225 mange by MGMT NET..

Here I want to add ER7206 Gateway for extra layer security. I already adopted by OC200. In OC200 under LAN, I create all vlan. But we know like Application Controll is only working under Interface.

So, How to config the Gateway to get benefit like Application Control?
