KEA DHCP - lacking features

I do notice that you dont have static ARP checked.

Yeah that for sure could be problematic - and currently static arp doesn't even work correctly using isc dhcpd.. Sure it sets them, but when your client does dhcp for it.. It switches from perm to dynamic in the arp table..

There is a thread and redmine about it.

I really wouldn't count on kea not being weird if your doing anything other than just serving IPs out of a pool..

So can I deduct that I have a run of the mill networks so kea works fine for me ? ;)

@Gertjan any network with a firewall is far from run of the mill ️ especially one running a new cutting edge kea dhcp server. Give yourself credit where credit is due.

Is there a way to get back to ISC DHCP if I clicked to migrate to KEA? If not, then I will check if any OPTION can be set directly into files, I need it for WAPD.

On that same page you can change back.

@SteveITS unfortunately I dismissed the banner and no other possible option found in the section. I'll workaround deploying another DHCP on another server while the module gets populated with more fields.

@omiwaaa this was just asked earlier today - you set it back in the same place you set it to kea..

@johnpoz thank you for giving me the opportunity to choose and force me to specify my DHCP OPTIONS

Hi,
I have 2 different subnets LAN and OPT1. I have a laptop, which has static IP address defined in both subnets, for lan the ip is 192.168.2.20, and for opt1, the ip is 192.168.3.20.

I have removed the client identifier in both subnets. Is there any work around for such scenario or I am missing something,
I have posted it in separate in topic before, hoping if somebody else ran in the same issue, but haven't heard anything
thanks,

I got the same error as you, and in my case it seemed to be that i had the same mac-addresses entered in "MAC Deny" on 2 different vlan-interfaces.
Fired up a VM and did the same settings and got the same result.

when i deleted the mac-addresses from 1 vlan-interface kea-dhcp worked again.

in this situation in the config file "/usr/local/etc/kea/kea-dhcp4.conf" the class is indeed being defined 2 times.

i assume this is a bug, but if someone else could confirm...

You want to report/confirm a bug in a feature that is listed as not supported yet, in the preview release?
