Host networking negatively influenced by VBox — at Initial Version

Description

Hi Folks!

Problem on WinXP/SP3 host, same with MS Vista Business 32 Bit/SP1: After installing VBox 2.2.2, the Dell 1600n scan driver doesn't work anymore. The Network Scan driver simply does not find the printer/scanner.

De-installing VBox leads to a working setup. Thus, I can say, that the inserted network module of virtual box is not completly transparent.

Setup: A switched network with two Windows PCs, each running WireShark. The system with VBox has an additional Host-Only Network. Furthermore, there is a Dell 1600n Printer/Scanner.

Abstract: When searching for a printer/scanner, the dell software broadcasts an UDP Packet with the source address of the host, destination address=255.255.255.255, UDP Port 1124.

Error description:

  1. Searching for the printer when VBox is NOT installed: the UDP-Packet is seen on the host running VBox, and the Printer/Scanner correctly responds.
  2. Searching for the printer when VBox IS installed: the UDP Packet is sent on the physical network interface with the source IP address of the Host-Only-Network.
  3. Disabeling the Host-Only-Network in the Windows Network Setup let's the UDP Packet vanish in whole.
  4. De-Installing the VBox Host-Only Network card does not help at all.

Is there anything more I can to do isolate the problem?
