I have installed and (mis-?)configured a DHCP v6 server. The server starts cleanly; it does not serve any addresses, not even the “fixed-address6 fd2f:4760:521f:3f3c::c0a8:456d” value for the host. I have clearly done something incorrectly.
DHCP6 is added to both the external and public firewalls.
Any suggestions where this has gone astray?
