DHCP does not include DHCP information for NAT network

Description
When configuring the guest's adapter for "NAT network", DHCP OFFER and DHCP ACK messages do not include any information related to DNS, even though the client (dhclient on Ubuntu 14.04 in this case) request options 6, 15, 119.
When the same adapter is changed to (plain) NAT, DNS NAME (15) and DNS NAME SERVER (6) options are suddenly included.
Creating a fresh NAT network and playing with its DNS settings did not fix the problem.
I currently work around this by adding a second (plain) NAT adapter, just for the DNS options.
While I experience it with Linux guests, it probably applies to other guest operating systems as well. The two packet traces attached to this show the messages exchanged for NAT network and plain NAT, respectively.

Most likely fixed in VBox 4.3.26.
This is probably a duplicate of #13918, a regression introduced in 4.3.24.
Please, try a test build from wiki:Testbuilds, revision 98815 or later.
