Just a quick comment to this “Do protocol analysis” setting.
I tried it also, but it did not help me either…
About the ethernet adapters on my pc, I am using Asus P5B Deluxe Wifi motherboard with 2 integrated 1Gbit ethernet ports.

It’s interesting. I also have an Asus P5B Deluxe (no wifi) motherboard in my desktop PC. It also has two integrated 1 Gbit ethernet ports.

Thanks for the info CobrAttila 
So maybe this could have something to do with the integrated LAN then…
I think the p5b deluxe and p5b deluxe wifi edition use the same marvell chips for ethernet connectivity.
At least the p5b deluxe wifi uses the following chips: Marvell 88E8001, Marvell 88E8056
I should have the latest ethernet drivers installed from asus support site, but I will check this to be sure.

Hey guys, can you try this rule?
Action = Allow
Protocol = UDP
Direction = In
Source IP = Any
Destination IP = The ICS adress of the host pc
Source port = 68
Destination port = 67
