	This may do the trick, but it depends on how your client
	application behaves.  From what I've seen in our logs, the
	browser isn't involved in the network-parameter-acquisition
	transaction (DISCOVER/OFFER/REQUEST/ACK), but needs a
	subsequent application-parameter-acquisition one (INFORM/ACK).

	I didn't see any DHCPINFORM request in the log fragments from
	Phibee NOC.  Are there any?  If not, then I would expect that
	the client application (browser, or whatever) simply isn't
	sending the request to the DHCP server.

	I hope this helps.
