I think I've configued lagg(4) into doing what I really want, which is
bind two interfaces together and balance the traffic in and out:
kernelconf:
device lagg
rc.conf
cloned_interfaces="lagg0"
ifconfig commands:
ifconfig igb0 up
ifconfig igb1 up
ifconfig lagg0 laggproto loadbalance laggport igb0 laggport igb1
xxx.xxx.xxx.22/24
ifconfig lagg0 xxx.xxx.xxx.220/32 alias
ifconfig lagg0 xxx.xxx.xxx.221/32 alias
ifconfig lagg0 xxx.xxx.xxx.222/32 alias
ifconfig lagg0 xxx.xxx.xxx.223/32 alias
route add default xxx.xxx.xxx.1
That results in something that looks like what I wanted, which was rx/tx
shared across two interfaces on the same network with:
-bash-4.2$ netstat -rn
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif
Expire
