DHCP question

Hi I was taught that this will not work, but I have been told it did work in the past?

What you might ask.

Well some one has set up a windows server with its network card on the subnet

10.159.0.1/24

and with a DHCP pool on the 10.159.1.0 / 24 subnet. Just the one pool.

So if a client on the same network segment as the servers nic sends a DHCP request as I understand it the server will not offer an address as it has no pool set up in the same range as its nic. (there are no helper address or relays set up on the network)

However they guy is swearing blind that it use to work.

Does that description make sence, and if so would you expect this to work or not?

Regards

    It should not work, but could be "tricked" into working if an incorrect subnet mask were used, eg. /23 or less as opposed to /24.

    Indeed, done that trick my self before, but not the case this time. I think the man is a fibber ;)

    Worked out a way to get it to work though :)

    Left the network card set o a /24 on the 10.159.0.0/24 subnet

    then in DHCP created a super scope,

    with one scope for 10.159.0.1/24 and one for 10.159.1.0/24

    disababled the 10.159.0.1 scope with in the superscope, and i will only server addresses from the second scope.

    And that is how to get a DHCP server so server a different subnet range to its own network card to clients on the same network segment.
