[SOLVED] ISC DHCP - KEA DHCP - LAN1 doesn't have any

[erica.vh]

Hello,
I've installed fresh the 25.7.2, and wondering what could I've done wrong (or not done) to get this:

In 'services' - 'ISC DHCPv4'  I only see LAN2 and LAN3, but not LAN1 ?

In 'KEA DHCP' - 'KEA DHCPv4' service is enabled, and all 3 LAN are selected, yet the service refuse to start, and so does 'dnsmasq DNS/DHCP'

In Dashboard - Services - dnsmasq is "stopped", a red square and a triangle to start it (click on it doesn't start it)

Any hint ?

NB: In 'ICS DHCPv4' - 'leases' , I have 4 Android devices "static" with prevention to connect unknown devices
while in 'KEA DHCP' - 'Leases DHCPv4' I have nothing, no static, no dynamic, and no option to add any

NB2: Reading further, I understand that KEA is an alternative to ICS, not a complement, and since I have only ~15~20 users, I'll stick with ICS, so I disabled KEA, which "solve" one of the three problems, dnsmasq still not started (Dahboard - Services - dnsmasq is stopped) and still no LAN1 under ICS DHCP

You either need to run Kea or ISC or Dnsmasq for DHCP services. You can't run all three at the same time, even on different interfaces. If you are going to stay with ISC, I suggest removing all interfaces from Kea/DNSmasq and then disabling Kea/DNSmasq.

Note that the recommended DHCP setup for small networks is to use DNSmasq. It is the default for the setup wizard for new installs. See here. https://docs.opnsense.org/manual/dnsmasq.html

Thank you, that did it !
Kea disabled (in my previous)
dnsmasq disabled
ISC DHCP kept (I find it more practical than dsnmasq)
All good !
