As i wrote into the topic, i'm trying to assign DHCP leases from a linux server, using a pre-configured MAC->IP table (more than 10 records), to all my WLAN clients (WPA+PSK).

But if i disable the DrayTek DHCP server i cannot see the WLAN DHCP REQUEST broadcasts on the LAN side, and no lease is given from the server to that clients.

If i enable DHCP relay agent on the Draytek the server reply with a DHCP lease with a random IP because it seems to see the DHCP request coming from the Draytek mac instead of the WLAN client MAC.

Why that?
