Hello,
Does the lightweight dhcp6c build up by OpnSense, do UDP flood in some circumstances?
I'm asking the question because I'm pfSense right now (thinking to switch over) and it have the issue, they are using the client from the freebsd release, and I have the issue most of the time at boot time.
It's known that dhcp6c sometimes does an UDP flood for some reasons,(https://sourceforge.net/p/wide-dhcpv6/bugs/34/)
thanks
