My opnsense had a static ipv6 on fibre, but now it's connected to a 5G modem instead.
I've changed the wan to dhcpv6
But still, if I go in shell, I see the old static ip
I've examined the backup xml, but the old ipv6 is not there.
I can remove it with ifconfig re0 inet6 2a02:xxx::2 delete but it reappears a little later
Where could it be hiding?
