The explanation of the DHCP helper maybe hasn't been too clear to the non-techie. The premise is that maintaining lists of IP addresses for hosts is administratively complex. DHCP allows a host to broadcast a request to be assigned an IP address. If the DHCP server is on the same physical segment as this host then fine, the server will respond with an address to use. If however the server is on the other side of a router (layer 3) then there is a problem. One of the functions of routers is to limit the propagation of broadcasts to other segments. So the router will not relay the DHCP broadcast request to the DHCP server and the host's request is lost. The 'helper' software will recognize the special DHCP broadcasts and forward them. That's the feature. I do not know the status of Bay software.
