USG210 - WiFI client unable to reach the DHCP from VLAN

dpower

Hi guys, I'm trying to achieve multi SSID network schema with USG210 and NWA5123. 
I had follow this example: https://businessforum.zyxel.com/discussion/1631/multi-ssid-how-make-it
But Wifi client can connect to the SSID and cannot get an address from the DHCP Pool. 
Please advise:)

dpower,
What's the ZONE of your vlan interface ?
Do you add the firewall rule to allow the vlan ZONE to ZyWALL UDP port 67 (DHCP server) ?

The problem with DHCP was the switch. 
But still I cannot get address from the correct vlan. From the WiFi I get always address from the default vlan1. If I try to connect to the same lan of the AP from my laptop with configured vlan (in example vlan10) - I can get address from the correct DHCP from vlan10. 
What it can be?

The switch ports connect to USG and AP need to transfer tagged frame in and out for vlan10.
In your case,
client--->SSID (AP)<--->vlan10 tagged frame<--->siwtch<--->vlan10 tagged frame<--> (vlan10)USG
