Hello,
I did a lot of checks to find out why fe80::1:1 is marked as duplicated on vtnet2. The only device where this address is used is indeed the opnsense installation. Further investigations brought up, that the switch is the reason. Several years ago I created an isolated port group for DMZ on it but probably forgot to save the running configuration into the startup configuration. So after a powerloss the switch no longer had that isolated port group. So the LAN and the DMZ interface could "see" each other via the switch. Oddly enough it never caused any problem until now. I now recreated that isolated port group on the switch and the duplicate mark is gone. THis time I made sure it is saved into the startup configuration.
