Setting Up Guest WiFi with Unifi Access Points and GL.iNet Gateway: Need Guidance!

MT2500 doesn’t have a SWITCH, it only has two PHYs.

Creating a 802.1q VLAN, VLAN id is 12 in this example.

Creating a interfaces for subnet 192.168.9.x

Creating a firewall rule, guest accept output, reject input and forward, and accept dhcp and dns

Now you can get a guest subnet 192.168.9.x from LAN(eth1.12 vlan id is 12).
