I've ran tcpdump on the vm's tap device, here is what I see: 01:42:15.404754 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 52:54:00:5a:4c:8c (oui Unknown), length 548 01:42:15.405075 IP Broadcom.Home.bootps > 10.0.0.40.bootpc: BOOTP/DHCP, Reply, length 300 01:42:15.735893 STP 802.1d, Config, Flags [none], bridge-id 8000.52:54:00:6b:1b:92.8003, length 35 01:42:17.718941 STP 802.1d, Config, Flags [none], bridge-id 8000.52:54:00:6b:1b:92.8003, length 35 01:42:17.846918 IP6 fe80::fc54:ff:fe5a:4c8c > ff02::2: ICMP6, router solicitation, length 16 01:42:19.702944 STP 802.1d, Config, Flags [none], bridge-id 8000.52:54:00:6b:1b:92.8003, length 35 01:42:20.450441 ARP, Request who-has 10.0.0.40 tell Broadcom.Home, length 28 I think that issue is this: 01:42:20.450441 ARP, Request who-has 10.0.0.40 tell Broadcom.Home, length 28 I'm not sure if this is expected but looks like my dhcp server ignores it. any thoughts on the matter? Dagg.
