<p><em>Update 2021-12-18: It looks like the rdiff-backup port has been removed from the FreeBSD ports tree, so installing it via the port is definitely not an option anymore. Also, the method described below works on FreeBSD 13.0 as well.</em></p>
<p>In <a href="https://www.lonecpluspluscoder.com/2020/01/16/building-an-openbsd-wireguard-vpn-server-part-2-unbound-dns-setup/">part 2</a>, I reconfigured my WireGuard VPN to use an Unbound DNS server on the VPN server rather than rely on a third party server I had used for the original quick and dirty configuration.

<p>In the <a href="https://www.lonecpluspluscoder.com/2019/12/27/building-an-openbsd-wireguard-server/">first part</a>, I described how I set up the basic OpenBSD WireGuard VPN server.

It’s been running well since, but I needed to take care of some overdue maintenance tasks. Trying to log into the server this morning and I am greeted with “no route to host”. Eh? A quick check on my Vultr UI showed that the VPS had trouble booting. The error suggests a…
