Hi and thank you for your help.
I am trying to setup my hap ax3 as router and wifi access point.
It should be connected to a managed switch, where my ethernet devices are connected to.
The ports on the mikrotik should just be used for WAN and the Trunk to the managed switch for now.
I started with the default configuration, which I then slightly modified so that I can have WAN on port 5 instead of the default port1, because I want to use the 2,5G connection between the managed switch and mikrotik.
In the Network I want to have for now 3 VLANS:
guest 10.10.0.0/16 on vlan-id 10
trusted 10.20.0.0/16 on id 20
mgmt 10.100.0.0/16 on id 100
I tried to setup things up as much as I could, and am at the point where I want to get ready to remove the default network & dhcp, so that I connect only via mgmt network from my PC to the managed switch on the vlan-id 100 access port. The managed switch is tagging 10-.20- and 100 vlans on the connection port to the Mikrotik.
I tried to set the port 1 on the mikrotik as trunk(as far as I understood), but it always disconnects me(thank you for Safe mode)
I have port 3 used as a direct connection to mikrotik now aswell.
One thing of note, between the managed switch and the mikrotik there is a POE injection device to power the mikrotik, but I hope this will forward traffic as expected.
Unfortunately only the 2,5G port is POE-in.
The problem is now, that I apparently did not configure the VLANs/Trunk correctly, because I can't connect to the Mikrotik from my pc via the Mgmt network.
I will paste my config in here, cutting out some details about the wifi:
