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

[Jeff Kletsky]

Thanks for the confirmation that "relay" is the intended way to approach 
this.

I don't seem to be able configure more than one relay *address* per 
subnet though.  The ip-address string only seems to accept a single 
address, not a CIDR- or dashed-range. If I try repeated relay 
statements, I end up with "failed to select a subnet for incoming 
packet" for all of the relays.

Is there a way to accept multiple relays for a given subnet declaration?


The notion of "positive" and "negative" selectors could use some 
clarification in the documentation. Without being immersed in the code, 
human-language versions of the clauses seem about the same:

* Client must arrive on an interface with an address in the subnet
* Client must belong to the given client-class


Thanks,

Jeff
