I am using two lagg interfaces :
lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=400b8<VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO>

laggproto lacp
laggport: igb1 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
laggport: igb0 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>

lagg1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=400b8<VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO>

I am not using ipfw nat for a while, and problem still occur.

route monitor didn`t show event that changes default router.
I  use a script in crontab to restore proper gateway, for now.
I am wandering:   is it dummynet issue, because we all using it.
My statistics of changing default gateway is follows
August 5
August 14
August 18
September 2
September 6

I will appriciate any suggestion in debugging that problem.
