Some more findings: - Problem can be seen with Linux 3.7 in the AP (VM), too. - *Problem disappears* if the bridge device br0 on the host is set to promiscuous mode. - Sometimes, there can be seen the warning "notebook dhcpcd[2784]: eth0: bad UDP checksum, ignoring" when starting dhcpcd on the notebook with br0 / host set to promiscuous mode (nevertheless dhcpcd worked fine). I never saw this warning before. Any idea how to fix the problem w/o running the bridge br0 on the host in promiscuous mode?
