DHCP server uddeler ikke ip-addresser

Jeg har opsat et netværk med en DHCP-server, som har ip 192.168.2.3. med et scope fra: 172.16.10.1-254 (til mine klienter).

Alle serverne er tilsluttet mit vlan 20 og klienter vlan 10.

Men min klient for ingen ip-addresse fra min dhcp.

Jeg kan pinge rundt og min dns, AD og web virker helt fint.
Kan dog ikke pinge fra min klient til noget (også selvom jeg prøver med en statisk ip på klienten).

følgende er opsat, nogen der har en idé ??
