Ticket #4103 (closed defect: fixed)
Host networking negatively influenced by VBox
|Reported by:||bauer40||Owned by:|
Description (last modified by frank) (diff)
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.
- 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.
- 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.
- Disabeling the Host-Only-Network in the Windows Network Setup let's the UDP Packet vanish in whole.
- De-Installing the VBox Host-Only Network card does not help at all.
Is there anything more I can to do isolate the problem?
