Router on a stick with WAN and LAN - unable to enable and cofigure LAN at all



  • Under new pfSense 2.3 it's impossible to assign/enable new LAN interface if previously doesn't exist. This is the case where you have a box with only one NIC, and your're trying to add VLANs to it.

    When creating the new interface, it complains that a DHCP6 Server is active thus cannot be saved. But since that inteface doesn't exist yet, there's no present config on DHCPv6 page.

    Detailed steps to reproduce here: https://redmine.pfsense.org/issues/6152

    This used to work well on 2.2.6 and before.
