Could you pls. try to create a couple of vlan interfaces (ifconfig vlan0 create...), than configure them with the same IP addresses/masks as you suggested earlier, and show us the results of this procedure? On my 4.6-RC system, such thing just don't work, thanks God. Marko To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
