Hi, I am trying to use VirtualBox since a while, however bridged networking never worked, even it is supposed to do so. My Host is: FreeBSD 8.0 / RELENG, 32bit, em0 ethernet I use a Knoppix LiveCD as a guest OS (also tried with debian and Windows) When I try to get an IP using DHCP the request is sent out to my router and is returned to my freebsd host. tcpdump on em0 on the FreeBSD host: 11:30:35.614121 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 08:00:27:25:17:97 (oui Unknown), length 300 11:30:35.614131 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 08:00:27:25:17:97 (oui Unknown), length 300 11:30:36.621477 IP fritz.box.bootps > 255.255.255.255.bootpc: BOOTP/DHCP, Reply, length 548 However it never appears back at my linux guest tcpdump on eth0 on the linux guest: 11:30:34.008830 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 08:00:27:25:17:97 (oui Unknown), length 300 11:30:43.004510 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 08:00:27:25:17:97 (oui Unknown), length 300 11:30:58.015919 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 08:00:27:25:17:97 (oui Unknown), length 300 There seems also to be some kind of packet duplication, as the packet sent at 11:30:34 appears twice in the tcpdump of the FreeBSD host. Any ideas how to debug this? Tobias
