FengZhaolin "Repo: 1. The host machine runs windows server 2003 sp2. 2. Create a guest system with hosted interface. (I tested with Ubuntu 8.04 and Windows Server 2003). 3. Host and Guests use static ip addresses. 4. Unplug the network cable. 5. Plug in cable again. 6. The guest machines is not accessible from outside. An external machine can ping the host, but not the guests. The host can ping external machines and the guests. A guest can ping the host or other guests, but not external machines. The only way to solve it is to reboot the guest machine." defect closed network/hostif VirtualBox 2.1.4 worksforme Windows Windows
