DHCP v6 Server fails after reboot of switch

[walkerx]

I had to reboot my switches today and after doing so I found later that the DHCPv6 Server was in a stopped state.

My setup is that my OPNsense is connected directly to my modem for the internet connection and then a switch for all my local devices.

RADVD was still running and even though my connection had not gone down, I only lost the DHCPv6 service on my network and only way to get the service back was to disconnect internet and reboot the server.

Surely should not need to do this when you've rebooted a switch, seeing that OPNsense is handing out the leases
