Title: Disable ISC when using Dnsmasq?
Post by: dropoff on May 21, 2025, 12:58:13 PM
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...

Jonathan.

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 :-)
