Hi, I am running on Debian sid which is still "stuck" with VirtualBox 4.1.18 due to Debian's freeze while preparing for a new release. I am, however, running more recent kernels. I build my network setup myself, with the guest connected to a bridged adapter, br0, and the host routing between br0 and its eth0 with the Internet connected. NAT is done via regular iptables rules. Up to kernel 3.5.4, this has been working fine.
With kernel 3.6.0 and kernel 3.6.1, however, NAT seems to be broken. I don't see the answer packets coming in from the internet going out on the bridge: eth0: $ sudo tcpdump -i eth0 -np host 8.8.8.8 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 14:22:04.047807 IP 192.168.218.24 > 8.8.8.8: ICMP echo request, id 512, seq 2560, length 40 14:22:04.072433 IP 8.8.8.8 > 192.168.218.24: ICMP echo reply, id 512, seq 2560, length 40 14:22:09.493030 IP 192.168.218.24 > 8.8.8.8: ICMP echo request, id 512, seq 2816, length 40 14:22:09.512335 IP 8.8.8.8 > 192.168.218.24: ICMP echo reply, id 512, seq 2816, length 40 14:22:14.500339 IP 192.168.218.24 > 8.8.8.8: ICMP echo request, id 512, seq 3072, length 40 14:22:14.519901 IP 8.8.8.8 > 192.168.218.24: ICMP echo reply, id 512, seq 3072, length 40 14:22:19.507119 IP 192.168.218.24 > 8.8.8.8: ICMP echo request, id 512, seq 3328, length 40 14:22:19.526081 IP 8.8.8.8 > 192.168.218.24: ICMP echo reply, id 512, seq 3328, length 40 8 packets captured 8 packets received by filter 0 packets dropped by kernel br0: $ sudo tcpdump -i br0 -np host 8.8.8.8 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on br0, link-type EN10MB (Ethernet), capture size 65535 bytes 14:22:04.047782 IP 192.168.19.22 > 8.8.8.8: ICMP echo request, id 512, seq 2560, length 40 14:22:09.493001 IP 192.168.19.22 > 8.8.8.8: ICMP echo request, id 512, seq 2816, length 40 14:22:14.500301 IP 192.168.19.22 > 8.8.8.8: ICMP echo request, id 512, seq 3072, length 40 14:22:19.507099 IP 192.168.19.22 > 8.8.8.8: ICMP echo request, id 512, seq 3328, length 40 4 packets captured 4 packets received by filter 0 packets dropped by kernel When I use KVM VMs on the same host, NAT is fine. Is it possible that there is something wrong with my old version of virtualbox when regarding current Linux kernels? I know what will happen when I admit using virtualbox on the LKML and would like to have comments from the virtualbox community first. Is this known behavior? Any hints will be appreciated.
