Yep, that worked!
Thanks for pointing that out.

I’m using Kea 1.1.0 on Ubuntu 18.04 for IPv6 only. The v4 server is not installed. It is serving addresses for the local subnet with no problem. I have a guest wireless network connected to an interface on my Cisco 1941 router. This router has a dhcpv6 relay destination of my Kea server. Tcpdump on the server shows that the server is receiving relayed DHCP requests from clients on the guest network, and the packets contain a link address which is valid in the subnet definition in the Kea config; however the server is not responding in any fashion to these requests. It’s as if they were not there at all. I have tried the “relay” IPv6 address option in the relevant subnet definition, even though it shouldn’t be necessary, but it makes no difference. I’m sure this worked for a while but now I just can’t make it work. Here is my config: { "Dhcp6": { "interfaces-config": { "interfaces": [ "em1" ] }, "lease-database": { "type": "memfile", "persist": true, "name": "/var/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 }, "preferred-lifetime": 3000, "valid-lifetime": 4000, "renew-timer": 1000, "rebind-timer": 2000, "subnet6": [ { "subnet": "2xxx:8010:631f:2::/64", "interface": "em1", "id": 2, "option-data": [ { "name": "dns-servers", "data": "2xxx:8010:631f:2::fd" }, { "name": "domain-search", "data": "my-domain.net" } ], "pools": [ { "pool": "2xxx:8010:631f:2::101-2xxx:8010:631f:2::1ff" } ], "reservations": [ { "duid": "00:01:00:01:1e:b7:90:35:f0:de:f1:00:93:b9", "ip-addresses": [ "2xxx:8010:631f:2::b" ], "hostname": "xxx-laptop1" }, { "duid": "00:01:00:01:20:54:28:1d:00:24:d7:68:ff:bc", "ip-addresses": [ "2xxx:8010:631f:2::4" ], "hostname": "xxx-laptop2" }, { "duid": "00:01:00:01:19:d5:b0:63:10:0b:a9:e5:72:04", "ip-addresses": [ "2xxx:8010:631f:2::7" ], "hostname": "yyy-laptop2" }, { "duid": "00:01:00:01:20:bd:bc:af:40:8d:5c:17:95:31", "ip-addresses": [ "2xxx:8010:631f:2::13" ], "hostname": "xxx-desktop" }, { "duid": "00:01:00:01:22:2D:F9:D5:D4:25:8B:11:73:99", "ip-addresses": [ "2xxx:8010:631f:2::17" ], "hostname": "yyy-laptop3" }, { "duid": "00:03:00:01:b4:b5:2f:0b:1c:cf", "ip-addresses": [ "2xxx:8010:631f:2::fe" ], "hostname": "printer" } ] }, { "subnet": "2xxx:8010:631f:64::/64", "id": 100, "option-data": [ { "name": "dns-servers", "data": "2606:4700:4700::1111, 2606:4700:4700::1001" } ], "pools": [ { "pool": "2xxx:8010:631f:64::101-2xxx:8010:631f:64::1ff" } ] } ] }, "Logging": { "loggers": [ { "name": "kea-dhcp6", "output_options": [ { "output": "/var/log/kea-dhcp6.log" } ], "severity": "DEBUG", "debuglevel": 3 } ] } } _______________________________________________ Kea-users mailing list [email protected] <mailto:[email protected]> https://lists.isc.org/mailman/listinfo/kea-users
