24.1 Legacy Series / Preventing Unbound Reload on ISC DHCP Configuration Change in OPNsense
« on: March 14, 2024, 03:39:51 pm »
I'm using ISC DHCP and Unbound DNS on an OPNsense server. Whenever I apply a configuration change in DHCP, Unbound also gets reloaded. Since I have a DNSBL with 3.7 million entries, this reload process takes about 5 seconds, causing timeouts for clients making DNS requests. How can I prevent Unbound from reloading every time there's a configuration change in ISC DHCP? Or does anyone have another idea on how to solve this problem?
