2 Wireless LANs and 2 DHCP Server

RouterOS Beginner Basics
1

Good day
I have the MikroTik RB2011UAS-2HnD-IN with RouterOS 6.1. I am very new to RouterOS.

I have a problem with DHCP address assignments. If you look at the section in red below, that is what causes the problem. When I change that to bridge-local then my router correctly assigns IP addresses from the 192.168.88.0/24 range to both Wireless LANS. I would like my router to assign IP addresses from the 192.168.6.0/24 range when users connect to wlan 2, and IP addresses from the 192.168.88.0/24 range when users connect to wlan 1. I will appreciate your assistance.

I have the following setup:
Wlan 1 - AP Bridge
Wlan 2 - virtual AP (with Wlan 1 as the master)

DHCP Server 1: 192.168.88.100 to 192.168.88.150 (interface: wlan 1)
DHCP Server 2: 192.168.6.100 to 192.168.88.150 (interface: wlan 2)

Addresses: 192.168.88.1/24 and 192.168.6.1/24

Wlan1 and wlan3 are both ports on the bridge

Routing set up for these addresses.

Pools set up for the DHCP servers.

Thank you

Good day

Thank you for your reply. I did an export compact. Here are the results (I just masked out my wifi passwords with XXXX and YYYY):

You need to remove wlan3 from the bridge. It looks like your already have and IP on wlan3 and the DHCP server setup for wlan3.

Thank you! It all works 100% now. I removed wlan3 from the bridge and now wlan3 assigns IP addresses from the 192.168.6.1/24 range.
Thank you for you help and quick replies. Now I can learn some other things, like setting up VPN and routing.
