Well, lucky me, I no longer need to do this as it looks like the problem was fixed in 13.0-RELEASE-p1 as part of an Errata fixed for "Kernel double free when transmitting on a divert socket". I tested with the new kernel and now running natd no longer causes a kernel panic. My one remaining beef with 13.0 relates to vultr more than anything else in that FBSD doesn't reboot when requested. It gets into some late-stage of the shutdown process and just spins on CPU. I can live with this one, but will keep an eye on it. Mark.
