problem with connect mikrotik and Unifi

RouterOS General
1

I have router hap AX2 and AP of Unifi U6+ .

On Unifi I have set 3 wifi network with 3 VLAN, on mikrotik I have bridge with 4 VLAN (3 for wifi, 4 for Unifi Device), and when I connect to wifi with my device, then I don’t have IP from DHCP-server. When I run this via ether cable then DHCP work great.
What I must have to working DHCP-SERVER from Unifi WiFi?
On sniffer and tcpdump on Unifi I see ARP who-has packets, and response, but not IP, when I settings static IP then I can’t ping mikrotik from wifi devices, but on sniffer I see ICMP Request…

What I can do for working this?

Can you confirm your unifi AP wants by default to accept the mangement vlan untagged into the router and all the data vlans as tagged (over the port leading from MT)??

Will depend, its either a trunk port to the UNIFI carrying all vlans and the management vlan ( the one that the UNIFI should get its IP address from ) could be one of the existing vlans if its considered TRUSTED, or, it would need to be a hybrid port.

Ok, now it works.

I have self-hosted unifi controller and on this I must check: “Multicast Enhancement” and enable this

on mikrotik I must add new vlan:

7 R vlan111-ether1 1500 proxy-arp 111 ether1

I not tested that proxy-arp is required or not (now), maybe later.

Add this interface to bridge and then wifi devices connected to my network and works great!

Thank you!
