[Kea-users] KEA DHCPv6 server ignores relayed solicitations

[Darren Ankney]

I don’t see any logging configured. Have a look at the logging section in
documentation. There are also a couple articles about logging on kb.isc.org.
You might get some logging without logging configured but you probably want
debug level logging setup to troubleshoot this problem.
