Clients not get IP address from DHCP server

[mamadou_oury_di]

Hello

I am on a project in which I have to depoiloyer vSZ 5.1.0.0.496 and AP R510 for one our customers. Diagrams below.
But I have a problem because the clients cannot get an IP address from the DHCP server.

Any suggestion will be welcome.

Thank you in advance

Hi,

Did you configured the wlan for each side?

Hi,

The WLANs configured are for all sites.

Are you configured it tunnel mode or distribution mode?
