Ok, i've just sniffed one of my MVP's initialising and what you should see in Ethereal is:-
Initial DHCP exchange, my DHCP service is on a linksys router so nothing to do with gbpvr.
Then the MVP does a broadcast (ethernet and IP) on source port 16868 dest 16867 to discover the server.
At this point, the gbpvr machine responds with an ARP broadcast to the MVP to perform IP/MAC address resolution.
Next, the gbpvr box sends UDP packets and looking in the packet payload, contains the reference to dongle.bin (no surprise there).
When this is complete, the MVP reboots, starts a DHCP process again, then the MVP arps to find gbpvr, then sets up a TCP session and that's about it.
If you can't make sense of your capture, if you want to just start an ethereal capture, unplug and reconnect the MVP, give it a while then save the capture file, you can email it to me along with your MVP MAC address and i'll see where it's differerent.
