[Kea-users] Configuring kea for relayed subnets *not* on its own interface's address

[Francis Dupont]

A client-class in a subnet may be used only to refuse a subnet selection.
 In your case your config requires a positive selector, for instance
a relay address (relayed messages) or an interface (direct connected
clients).

PS: there is a third possibility for unicasted messages where the subnet
specification matches the client address, cf "How the DHCPv4 Server Selects
a Subnet for the Client" in the manual.
