    DHCP assigining incorrect scope to device

    I have a HP pc which is being authenticated via its MAC address and assigned to vlan 2 by my HP 5406zl switch. I have confirmed all this works.

    Now, when it does a DHCP discover request, the router passes it on to the DHCP server like it should. However, the server then offers an IP from the wrong scope.

    VLAN 2 has the range 10.5.140.1 - 10.5.140.126, with the ip of the VLAN/router being 10.5.140.1 and the netmask being 255.255.255.128

    VLAN 1 has the range 10.5.143.1 - 10.5.143.254, with the ip of the VLAN/router being 10.5.143.1 and the netmask being 255.255.255.0

    When I inspect the dhcp offer packet, it has the relay agent IP as being 10.5.140.1 also.

    What is going wrong?

    It doesn't seem to be having this problem anywhere else though... Just this one PC is having trouble...
