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

Yes because how to get IPs through internet from DC to site?

it's not the Internet but the client's intranet.

What is the mgmt vlan? It's configured static on the AP?
What is the w clients vlan?
