This is a follow up to Two bridges sharing one port
Model : hAP AX Lite (=Device)
Goal is to have the following:
- Wifi and Ether 2 - DHCP server by router OS om Device; access to internet through WAN
- Ether 3 - DHCP client, passthrough to the WAN DHCP Server; access to internet through WAN
- Ether 4 - make sure i always retain access to the device
I followed (I hope) the instructions by @CGGXANNX and i must be missing something.
The following works:
- Ether 4 - gets an IP and can access the Device through WinBox; no internet access (as expected)
- Ether 3 - gets a correct IP from WAN DHCP server, has internet access
- Ether 2 and Wifi - No IP assigned and as such no internet
Here the config file:

Where did i miss following the instructions ? or is something else going on
Thanks,
