OPNSense deprecated (is deprecating?) the included ISC DHCP server and now has the Kea DHCP server as standard. I migrated to from ISC to Kea in OPNSense and it was relatively painless, and it's been working well since. No complaints here, but my setup is pretty vanilla.

I can't comment on the DNS integration, but I might look a bit deeper because it sounds useful.

Once day I will stop procrastinating and migrate my pfsense boxes over to Kea. I hope I like it.

I'll be thrilled if the expected DNS integration works and I don't get the side effects I get now from ISC.

I migrated my home router over to Kea and was distinctly unimpressed - it just carried on working 8) I do run a pretty full on pfBlocker-NG. I run quite a few other pfs too (31).

At work I have a CARP cluster of two elderly Dell servers with a lot of NICS. I have a change logged for next week.
