Built a tool to help migrate OPNsense ISC DHCP to Kea or dnsmasq.
It can migrate static mappings, DHCP options, subnets, IPv4 + IPv6, etc. from config.xml.
Made this originally for client migrations and expanded it after requests for dnsmasq support.
If anyone wants to test it (snapshot first), feedback welcome:

Are you using ISC-DHCP? It's being removed from OPNsense Core in 26.1 (due 28th January) to plugins, you may want to checkout the 26.1 release candidates before upgrading.

Replacing the keyboard on an MSI GP70 2PE, all laptops should be this easy!
No screws, clip out keyboard, unplug, plug in replacement, clip back in place.
Hands down, the easiest keyboard replacement I have ever done, and I've done a lot.

I have another video coming out at 4pm GMT today, which is an update to https://youtu.be/1Jop4u8Gnc4 which is a guide on how to use the new blacklists I mentioned, and a look at if you should upgrade - addressing any issues found over the last week.
I think OPNsense 25.7.9 is going to be released before it 🙃
How do you feel about updates? To frequent?
Did you know that you can lock OPNsense to specific firmware version to upgrade to and stay on until you change it?

Just hit 2 million views on the channel, you're all amazing - thank you for the support!
I’m planning the next round of videos for 2026 and would love your input.
What tutorials or topics do you want to see next?
More in-depth OPNsense/pfSense and FreeBSD stuff, or deeper TrueNAS or Proxmox dives?
Thinking about a “Switch to Linux” series.
Open to ideas.

For anyone who has been experiencing issues with the OPNsense Tailscale plugin after pre-auth key expiry. I've submitted a patch, should be available im v1.3 once it's been reviewed and merged.
