Hello
i use kea 1.4.0P1 with sample config but kea server seems not to answer
to Cisco BNG request.
* interface eth1 is on private address : 172.21.1.50/24
* giaddr ip address talk with kea is 192.168.11.254
* 192.168.11.254 is gw for pool configured on kea
* i add static on kea to reach 192.168.11.254 and both can ping each
other (ccisco-bng ->kea and kea->cisco-bng)
Here is kea-dhcp4.conf
