That's strange. However, to avoid problems with broadcast/multicast packet duplication (and for other reasons), if you have multiple IP interfaces on the same LAN, you need to put them together into an IPMP group. Thankfully, this is easy to do: ifconfig e1000g0 unplumb ifconfig e1000g1 unplumb ifconfig e1000g0 plumb group ipmp0 up ifconfig e1000g1 plumb group ipmp0 up ifconfig ipmp0 dhcp ifconfig ipmp0:1 plumb ifconfig ipmp0:1 dhcp You should end up with two DHCP-assigned IP addresses on ipmp0 and e1000g0 and e1000g1 will be used to send/receive packets. You will also be able to pull the cable from e1000g0 or e1000g1 without disrupting any of your connections.
