Indeed I've never seen that before. Speculation but perhaps it uses a random port if 67 is in use? Maybe Kea was somehow still running?
I've switched back and forth between ISC and Kea many times and never managed to trigger anything like that but....I would restart the dhcpd service. Failing that reboot.

OK, I re-installed 4 times from the downloaded image.
I finally found out about one problem and got that fixed on the last and current install.

They both serve me via DHCP, the same subnet when they are different in the settings.

You don't have your networks actually isolated then..
You can't just plug into the same dumb switch.
-
It is not a switch it is a pfSense router with different physical ports assigned to different interfaces, different DHCP servers and different subnets. So where in pfSense do I see/change the isolation??
-
@MidGe48 what do you have plugged into pfsense interfaces? Your saying you have a single device plugged into Opt1 and it gets an IP from dhcp on a lan or opt2 network?
What plugs into pfsense interfaces where you setup these networks and are running dhcp.. You can not just plug in lan, opt and opt2 into the same dumb switch.. And then plug a PC into one of the other ports.
-
I am well aware of what you say.
I have a relatively complex topology for my whole network including 3 routers and 4 switches. But what plugs in the ports of my perimeter router (pfsense) are physical networks totally isolated from each other. I don't know where you got the idea that I was converging things via a dumb switch.
Anyway, I am done for now, here.
I have other tasks awaiting and will use a workaround for the time being.
Thanks all.

totally isolated from each other. I
Clearly they are not - because there is NO possible way for you to get a dhcp address from some other network that is on different layer 2 network.
Or your network is so complex you don't know what is plugged into where, and what you think is connected to opt1 is connected to lan or opt2 or whatever network you device is suppose to get dhcp from opt1 is on

One suggestion : stay away from 10.10.10.1/24, as that one is by default used by pfBlockerng.About these networks, they are set up with a /24 each, right ?
Like : my OPT1 called PORTAL :
and dhcp :
When I check my DHCP logs, I can see :
So, on the igc0 (my LAN) (network 192.168.1.1/24) and the 192.168.1.31 is served.
on the igc1 (my OPT1) (network 192.168.2.1/24) and the 192.168.2.6 is served. -

What was the problem? I'd love to know what could possible cause dhcpd to listen on a different port like that.

Yeah - what would be the point, if dhcpd can not bind to 67, it should just fail with an error could not bind, etc.
Not like dhcpd could work if not listening on 67
