Hello,
I finally got my 4port opnsense firewall on a lagg LAN interface. Originally i had 1 port LAN, 1 port CARP and 1 port WAN setup having 1 port left.
But after creating a lagg interface on the free port, enabling the dhcp on it and disabling dhcp on the 1 LAN and the LAN device itself, I could add it to the LAGG interface.
But now the NAT Portforward (with the anti-lockout rulez) device is set from the original LAN device to the CARP device.
Where could I change it to the LAGG device?
