cAP ac as Access Point with external DHCP server

RouterOS General
1

Hi.

I have searched for and read and watched many tutorials, but none address my issue.

I need a simple setup to have my cAP ac RouterBoard as a wireless Access Point (both 2.4/5GHz), which is connected (eth1) to my Ubiquiti EdgeRouter-X ethernet port, which should serve DHCP leases to the wireless clients as well as to the wired clientes connected to the ER-X ethernet ports.

I have tried many combinations, say connecting to LAN port on ER-X and disabling DHCP server, trying to configure DHCP Relay on the cAP, setting bridges and so forth, to no avail. It’s certainly my fault but I lack the knowledge to get this to work.

The desired setup is as follows:

    10.100.1.10           <IP here?>  10.100.1.44     10.100.1.1/24 (DHP server)
[client PC] -------Wi-Fi-------[cAP ac] eth1--------- eth4 [EdgeRouter-X] eth0 -------Internet
                                                           |
                                    10.100.1.20            |
                            [Wired PC 1] eth -------- eth2-|
                                                           |
                                    10.100.1.30            |
                            [Wired PC 2] eth -------- eth3-|

Any advice on how to configure the cAP ac (address pools, DHCP relay) and the DHCP server on wired (main) router would be greatly appreciated.
