RB951 - use VLANs in switch and WLAN

Hi,
I’m trying to config a RB951 with this logical … I need one port trunk with 3 VLAN, 2 ports for VLAN2, 2 ports for VLAN3 and WLAN with VLAN3

TESTS …

CONFIG A - Switching
Switch 1 - Eth1 to Eth5 (Eth1 Master Port)
Eth1 trunk port with 3 VLAN: 10, 20 & 30.
VLAN 10 for management - IP 10.10.0.X
Eth2 & Eth3 with VLAN 20
Eth4 & Eth5 with VLAN 30
WLAN with VLAN 30

CONFIG B - MIX
Eth1 WAN - Trunk port
Switch 1 - Eth2 to Eth5 (Eth2 Master Port)
Eth2 VLAN 10 for management - IP 10.10.0.X
Eth3 VLAN 20
Eth4 & Eth5 with VLAN 30
WLAN with VLAN 30

CONFIG C - Routing
Eth1 Trunk port
Eth2 - VLAN20
Eth3 - VLAN20
Eth4 - VLAN30
Eth5 - VLAN30
WLAN - VLAN30

I tested with routing, switching, and mix both, but one thing work ok, and some others no. I think my config are wrong.
How is the best way to do ? ROUTING, SWITCHING, MIX.

An example will be appreciated.

Ciao.
