Port forward over wireguard to VPS with static IP

This is write up is on how to port forward over wireguard. I am going to be port forwarding a mail server running MailCow on my local server, but really any service can be port forwared with some modifications to the IPTables commands in the wireguard file.

I am using a cheap Vultr VPS as my proxy server, if your intrested heres a referral link https://www.vultr.com/?ref=9019507 where I get $10 or if you plan to spend more then $35 on your account you will get $100 and I will get $35 https://www.vultr.com/?ref=9019508-8H

My Setup

Debain 10 Buster
Tunnel subnet: 10.1.1.0
Proxy-VPS Tunnel IP: 10.1.1.1

Frequency Testing

This will allow you to test a specific frequency that you hear when you do your resonance testing in Klipper and potentially track down where extra peaks are coming from. If something is rattling at a specific frequency, you can specify that frequency and feel around the printer until you track it down.

Code was adopted by zifnab from somewhere in Klipper.

Usage

You have to have [resonance_holder] in your printer.cfg.

The command is HOLD_RESONANCE AXIS=<axis> FREQ=int SECONDS=<seconds>
