When upgrading #opnsense I would have really liked to know in advance that it would remove my DHCP static ips and remove the current DHCP server without automatically enabling the new #Dnsmasq server.

I've found this wasn't very clear in advance.

Both having to first create static routes to reconfigure as well as having to rebuild my ranges and static IPs from memory was a pity.

Having a single DHCP server do both the IPV4 and IPV6 in one overview is really nice though!
