L2 hell with Mikrotik and VLAN tags
Henlo,
i am having quite the trouble with my RB5009 router where I'm trying to create a VLAN for my various IoT devices. All ports are under a common bridge and this VLAN should either be reached using access ports (with non-vlan-aware devices) or via an ethernet port on which a proxmox server is running (where i will tag container ports with vlan 93).
However, i believe i am missing something because while i can succesfully get an IP via proxmox on any ethernet port by using VLAN 93, non-VLAN devices on port ether5 and ether6 do not get any kind or traffic. It looks like everything is dropped directly at the port, and i don't know why.
This is my current configuration:
[admin@MikroTik] > /export
/interface bridge

Does anybody have any idea on where my mistake is?

What version of ROS? No firewall?
No ARP on the bridge? Try
/interface bridge set arp=proxy-arpIt's Mikrotik, that's why.

I've tried, ARP is enabled but even proxy-arp makes no difference
I didn't look at which switch chip that model has, but see if the chip has a VLAN table. Possible the VLAN gets handled within the chip. Understand that I don't know exactly what is wrong but I am throwing out some ideas.
Nope, the integrated switch "Marvel 88E6393X" does not seem to have any kind of VLAN setting.

For the moment I am away out of town, bare with it a little, I can help you out later with this.
VLAN is HW-Offloaded on 5009.
but as I saw your settings, you will have to drop all config, it is wrong in all ways.
In MKT you only work in the SW chip on gen CRS Switches 1 and if you use L3HW offload ( 5009 is not part of this )
Write what ports you wish to be Access with what VLAN and what ports you wish to be Trunk.

Access ports should be the one i named _iot, with VLAN 93. All other ports should be trunk or no VLAN.

@foxone
I will import this on a 5009 and modify it for you tomorrow
