OpenVPN produces DCHP NAK bomb on Win 7 64bit — at Version 2

Description (last modified by JJK)

when launching OpenVPN 2.1.4 on Windows 7 64bit it sometimes results in a DHCPNAK bomb in the event log; the end result is that OpenVPN manages to connect but the routes are wrong.
I've managed to capture the traffic on the tap-win32 (tap-win64?) adapter during the connection process:

A second dump without IPv6 traffic can be found here:

A third dump for OpenVPN 2.2-RC is attached (30 KB)
