Hi all,

I have a (hopefully) simple question. I have a KEA DHCPv6 server v2.0.3 running 
on a Ubuntu 20.04 machine. I am trying to get it to respond to solicitations 
coming via an ISC DHCPv6 relay, but I see no activity from my DHCPv6 server 
when the relayed solicitations arrive. Is there any specific configuration in 
KEA needed for this to work, or can I troubleshoot it somehow? I can see the 
solicitations coming in on the correct network device using tcpdump. 
Solicitations that are not relayed are handled correctly by the DHCPv6 server.

I have a very basic configuration where this issue is happening that I am 
attaching:

{
  "Dhcp6": {
    "server-id": {
      "type": "LL",
      "persist": false
    },
    "interfaces-config": {
      "interfaces": ["enp1s0.10"]
    },
    "control-socket": {
      "socket-type": "unix",
      "socket-name": "/tmp/kea-dhcp6-ctrl.sock"
    },
    "lease-database": {
      "type": "memfile",
      "lfc-interval": 1800,
      "persist": true,
      "name": "/var/run/kea/dhcp6.leases"
    },
    "expired-leases-processing": {
      "reclaim-timer-wait-time": 10,
      "flush-reclaimed-timer-wait-time": 25,
      "hold-reclaimed-time": 3600,
      "max-reclaim-leases": 100,
      "max-reclaim-time": 250,
      "unwarned-reclaim-cycles": 5
    },
    "renew-timer": 375,
    "rebind-timer": 600,
    "preferred-lifetime": 3000,
    "valid-lifetime": 4000,
    "subnet6": [
      {
        "subnet": "fd80:501:ffff:100::/64",
        "pools": [
          {
            "pool": "fd80:501:ffff:100::10:1-fd80:501:ffff:100::10:FF"
          }
        ],
        "interface": "enp1s0.10"
      }
    ]
  }
}

Thank you,
Oskar
