Bring down WAN interface

[Steven-B]

Hi All,

I want to bring down the WAN interface intentionally, preferably scripted for something I would like to test in a CARP setup...
I notice that my script is actually doing what it's suppose to do, but for some reason I cannot bring down the WAN interface on the CARP BACKUP system.

Like for example: ifconfig vtnet0 down, the interface goes back up after several seconds... which is not what I want...
I also have been looking and came by configctl interface linkup stop vtnet0 but it results in the same behaviour...

Is there any way to come around this so I can manually decide what interface should be up or down?

Regards,
Steven

Coming back to my own question :), For those who are interested in this because I know a lot of people are trying to use CARP with a single ISP (DHCP/DHCPv6/...) running into some problems like I do... I am currently scripting this to CARP events so that in case of MASTER/BACKUP the WAN link on the BACKUP stays down until needed.

Bringing the interface down:
pkill -f dhclient
pkill -f dhcp6c
pkill -f dpinger

ifconfig <iface> -alias <wan-ipv4>

ifconfig <iface> inet6 <wan-ipv6> delete

configctl interface linkup stop <iface>

ifconfig <iface> down

Bringing the interface up again:
configctl interface linkup start <iface>
configctl interface reconfigure <iface>

I might post a full script etc. if wanted...

Regards,
Steven
