Hi, an amateur here, so go easy. I have started using Dnsmasq for DHCP, which I am happy with, however on a restart, ISC starts up first, thereby disabling Dnsmasq.
I do not use Unbound, and Dnsmasq is set to port 53. I do not see a way to remove the ISC service, since it is not a plugin. I can log in and stop ISC and start Dnsmasq, but by this time ISC has already 'grabbed' my static allocations. If I uncheck all the entries in ISC, and reboot opnsense, I am locked out, since Dnsmasq did not start (I had to log in via the console to re-enable it). I am up to date on 25.1.7_2.
Could I change the service start-up order to overcome this?
I'm probably missing something really obvious...

Disable ISC for all interfaces, then the service will stop. You cannot mix-and-match ISC and DNSmasq DHCP.
Thankyou, I did try that, but must have missed a 'save'. It's working as expected now :-)
I am using latest opnsense (updated today) and when its rebooting isc takes over - even after saving and using dnsmasq while building my network.
Very annoying. Found this thread when googling for a way to permantly delete isc in my opnsense. Cant find any way other than disable the service which then reloads after reboot on my machine :(
You must have forgotten to disable (and save) ISC DHCP for one or more interfaces.

Could be. I will double check to save and see how it behaves in the future. Thanks again for all our help :) (I have not gotten the time to dig in to the other topic you helped me with yet 😇)
