15.1.4 - IPv6 on WAN interface crash

[Dominian]

Just did a new install of opnsense 15.1.4 last night and as a test enabled IPv6 on the WAN interface.

This caused the system to go into a reboot loop and crash each time.

I had to unplug the wan interface, let it boot, go in via the LAN, disable IPv6 on the WAN, and then plug back in to get back up and running.

Just FYI!
