What does Kea log exactly? Does it get a packet, starts processing it
and then fails to send a reply? Or does it not get any packets at all?
You may enable logging on debug level to find that out for sure.

In general, Kea should be able to figure out the subnet to interface
matching. But you can help Kea a bit there. You can also tell Kea
explicitly that a subnet is available via certain interface:

{
  "subnet": "192.168.2.0/29",
  "interface": "igb0",
  ...
},
{
  "subnet": "192.168.3.0/28",
  "interface": "wlan0",
  ...
}

If that doesn't help, please enable debug logging and send Kea's output
when packet is sent on igb0.

p.s.
You can skip code, space and csv-format in option definitions, if you
want. Kea will figure out the code on its own if you provide correct
name and space and csv-format have default values.
