While you're looking at tcpdump, check that the client is asking for
option 52. To avoid confusing a client, the dhcp server only sends the
options the client asks for.

If it's the ISC dhclient, you want something like

    also request dhcp-option-overload;

See dhclient.conf man page in this case.

Other clients will do something similar.
