I run Wireguard at my public VPS. I run Wireguard on my clients at home. I have Wireguard on the server configured to route via iptables, the ports I desire to send that traffic to my home machines.
This is a good resource: https://www.linuxbabe.com/ubuntu/wireguard-vpn-server-ubuntu
If this pastes correctly, here is a redacted version of my server and client config:

# Client (the actual self-host local server)

#AllowedIPs = 10.10.123.0/24

I use sar for historical, my own scripts running under cron on the hosts for specific things I’m interested in keeping an eye on and my on scripts under cron on my monitoring machines for alerting me when something’s wrong. I don’t use a dashboard.
