Hi there;
I posted this on Questions but decided to give it a shot here.
PC:
FreeBSD 11.2-STABLE #0 r336831
16 GRam
Intel i5 8th gen
rc.conf:
wlans_iwm0="wlan0"
ifconfig_wlan0="WPA powersave"
ifconfig_re0="media 1000baseTX mediaopt full-duplex up"
ifconfig_re0="ether f8:94:c2:26:f3:54"
ifconfig_lagg0="up laggproto failover laggport re0 laggport wlan0 DHCP"
wpa_supplicant_enable="YES"
wpa_supplicant_program="/usr/local/sbin/wpa_supplicant"
cloned_interfaces="lagg0"
OBS - tried cloning re0 MAC into wlan0 and it didn't work, so i cloned
wlan0 MAC into re0 and every thing worked.
ifconfig:
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=80088<VLAN_MTU,VLAN_HWCSUM,LINKSTATE>
ether f8:94:c2:26:f3:54

groups: lagg
laggproto failover lagghash l2,l3,l4
laggport: re0 flags=5<MASTER,ACTIVE>
laggport: wlan0 flags=0<>
With these settings, host's lagg interface works seamlessly with
wired/wireless.
The problem:
I have several VMs on this machine. On everyone of them, their network
interface is configured to bridged on lagg0.
If the master (re0 wired) is active, any VM has network connectivity, If I
unplug the cable, lagg0 switches over wlan0 and the host never looses
connectivity, BUT the VMs do!
Even if boot with the cable unplugged, the host has perfect connectivity
but any started VM doesn' t.
I can't think of a reason why this is happening and google didn't help, so
decided to post here and see if anybody could share any thoughts.
Thanks,
