switch vlan missconfig

I’m missing out on something with the vlan setup. On a hAP AC running ROS 6.39.1 the goal is to use switching on port 3-5, while ports 1 and 2 are standalone. Port 5 is the master port. On port 4 and 5 I want tagged vlan1 and vlan2, while on port 3 I want vlan1 to be untagged. In my current config, port 4 and 5 is working as wanted, but port 3 is not. I think port 3 either rejects incoming untagged packets, or does not strip tag from packets. Is anyone able to see why port3 does not work as wanted?

/interface bridge
add comment=defconf name=bridge
add name=bridge-wlan

/interface ethernet
set [ find default-name=ether2 ] name=ether2-master
set [ find default-name=ether5 ] comment="wlan kjokken" poe-out=off
set [ find default-name=ether3 ] master-port=ether5
set [ find default-name=ether4 ] comment="wlan oppe" master-port=ether5

/interface vlan
add interface=bridge-wlan name=vlan1 vlan-id=1
add interface=bridge-wlan name=vlan2 vlan-id=2

/interface ethernet switch port
set 2 default-vlan-id=1 vlan-header=always-strip vlan-mode=secure
set 3 vlan-mode=secure
set 4 vlan-mode=secure

/interface bridge port
add bridge=bridge comment=defconf interface=ether2-master
add bridge=bridge comment=defconf interface=sfp1
add bridge=bridge-wlan interface=ether5

/interface ethernet switch vlan
add independent-learning=yes ports=switch1-cpu,ether5,ether4,ether3 switch=\
    switch1 vlan-id=1
add independent-learning=yes ports=switch1-cpu,ether5,ether4 switch=switch1 \
    vlan-id=2

Are noone able to see where I went wrong with this?

Dont tagg vlan1, its never a good setup. Rather change whole setup to use vlan100 and vlan200 or something like that, and bridge it with an interface haveing vlan1 untagged where you want that. and upgrade to newest ros. The vlan/switch setup is easyer to understand.

Ikke bruk vlan1 tagget. Det er veldig sjeldent noe bra. Prøv å bruke feks vlan100 og 200 på din innstallasjon inne i routeren, og bride inn vlan1 untagget der du trenger det. Skal du videreføre vlan1 fra en router til en annen, bridge vlan1 utagget med feks vlan100 før du sender det ut av routeren. Oppgrader til nyeste ros. da bruker du ikke master interface etc.
